After two fulfilling years working at the Node and Development, I have decided to move on and embark on a new adventure. That means, my job is up for grabs! I’ll probably write a more personal reflection closer to my leaving day in mid-July, but for now, I’d like to briefly talk about what this role entails and hopefully persuade some of you to apply!
If you’re interested in science communication and would like to help contribute to the developmental and stem cell biology community in a unique way, this role might be a good fit for you! You’ll still be very much in touch with the scientific community, even if you’ll no longer be running experiments. If you know anyone who might be interested, do share this opportunity with them.
Below are my main tasks:
Running the Node
Commission content: behind the paper stories, interviews, meeting reports, discussions, perspectives… anything you think the community will be interested in reading about
Provide editorial feedback on drafts from researchers
Write and produce your own content
Manage the Node’s social media channels: Bluesky, X, LinkedIn, Facebook
Maintain and develop the site: make sure the site is up-to-date, provide user support, and steer the development of the site (we are turning 15 this year and as the online environment continues to evolve, there are always opportunities to try out new things)
Working as part of the ‘Community Managers’ team
Collaborate with the two other community managers of preLights and FocalPlane: we share tips on running our sites, bounce ideas and co-organise webinars and workshops
Provide cover and support
Working as part of the Development team
Write Research Highlights: usually once a week
Conduct interviews: ‘people behind the papers interviews’, longer single-person features of scientists from a variety of career stages
Manage the journal’s social media channels: Bluesky, X, Facebook, Instagram
Help out with the Development presents… webinars: promotion, video editing of the recordings
Write press releases
Attending conferences
Go to meetings and conferences, both within the UK and abroad, mostly society/community-based meetings: represent the Node/Development, promote our work, network with people, learn about the latest science
Jamie: A bit of a mad mixture. The lab has always worked on organogenesis and self-organization in development, at the bench and at the computer. For around 20 years, we have combined natural development with tissue engineering, with a special interest in 3Rs applications as well as eventual clinical use. We were among the founders of the now burgeoning field of synthetic morphogenesis (our first publication, 2008). Many in the lab want to use it to make useful living materials; the PI has an interest in using synthetic biology ‘re-creating’ developmental mechanisms that we think we understand, in a very simple form, to check that we really do understand them (a bit like testing understanding of aerodynamics by making a paper ‘plane’). We began this by making synthetic patterning systems, and then added creation of shape. The next step is engineering agency and purpose. In addition to this, and almost by accident, we have a strong interest in pharmacoinformatics and run the global drug database for IUPHAR, the International Union of Basic and Clinical Pharmacology, and the antibiotic database for the Global Antibiotic Research and Development Partnership. Sadly, the IUPHAR meetings, which I have to attend, almost always clash with the BSDB spring conference.
From left to right: Wentong, Jane, Sneha, Elena, Natalia, Louise, Rhiannon, Jamie, Hüseyin, Simon.
Roll call (in order of length of time in the lab):
The lab gremlin, in the lab from time immemorial; spends its time corroding electrical connections, moving critical antibodies to the wrong fridge, and emptying CO2 cylinders overnight. Like magnetism, it is invisible but we know it to be present by its observable effects.
Jamie Davies, Professor and anyone’s-technician-in-a-crisis (the jobs go together); now grey-haired enough to have made most of the mistakes people make in research, so is able to help young scientists avoid them and instead discover new and exciting mistakes of their own.
Jane Armstrong, Senior Curator, who joined as a wet-lab post-doc over 25 years ago and later discovered the joy of informatics.
Simon Harding, Senior Developer, a molecular biology post-doc turned software wrangler, with the group for over a decade now.
Elena Faccenda, Curator, a pharmacology post-doc turned informatician, also in the group for more than a decade. As well as managing the database, Elena, Simon and Jane write high-profile papers together, and have each acquired h-indices higher than many full professors.
Rhiannon Beadman, a post-doc working on homeorhesis and error-correction in organ development, uses a mix of classic 1920s-style cut-and-paste embryology and up-to-date molecular techniques.
Hüseyin Gül, a PhD student of this lab turned post-doc; works on a new drug target he identified for polycystic kidney disease.
Natalia Penar, a PhD student; combines optogenetics and morphogenetic control to test hypotheses about symmetry-breaking in branching morphogenesis.
Sneha Ravi, a PhD student; uses our new patented biofabrication technique to engineer ureters and similar tubular tissues.
Louise Goossens, a PhD student who will use Sneha’s ureters to model bacteria-tissue interactions, and how they affect antibiotic resistance, in urinary tract infections.
Nick Younger, a post-doc just joining us to work on optogenetics and axioloids.
Wentong Fu, an MSc project student working on dynamics of pattern coarsening following wounding of a synthetic patterning system.
Favourite technique
Jamie: Reading developmental literature from a century or more ago; researchers then did not have our fancy tools, but they had observation, insight and imagination and their work is an unfailing source of inspiration.
Outside your own work, what are you most excited about in developmental or stem cell biology?
Jamie: Evo-devo generally. I have never worked in this area, but seeing links develop between understanding of developmental opportunities and constraints, and the areas of morphospace visited and avoided over phylogenetic evolution, is amazing and is a ‘new’ new synthesis.
How do you manage your group and your various tasks?
Jamie: I ‘manage’ with as light a touch as possible. If you give bright young people the right encouragement, they will ask interesting questions and do interesting things, many of which I would never have imagined. In recruitment, I value diversity, not just in terms of ethnicity, gender and religion, but also in terms of academic culture; my lab has included people with first degrees in philosophy, anthropology, mathematics, and engineering as well as in biological subjects, and has benefited from the different ways of thinking they bring. As for managing my own tasks, the golden rule is not to procrastinate, and to reserve time just to think; I mean actually reserve it in a calendar, with the same non-negotiability as one marks out a timetabled lecture or conference. Thinking is part of a scientist’s job, and it is entirely reasonable to demand time in which it can be done.
What’s the best thing about where you work?
Answers given by members of the lab in general include: “I like how everyone in the building helps each other…. I love my daily commute to work through the Meadows.” “It’s a space where complex problems turn into exciting challenges that motivate me to learn, experiment and grow. It’s a mix of curiosity, teamwork, and the occasional lab triumph—it’s never dull!” “The people! As a biocurator and office-based scientist, it is great to still be part of an academic research laboratory, especially one that is so supportive. Being based on a campus right in the heart of Edinburgh is pretty special as well.” “The lab is friendly and supportive — and seems to benefit from lots of different experiences.” “I enjoy the intellectual stimulation that researching for the Guide to Pharmacology brings. A huge bonus is working with competent and friendly colleagues who help you through the days when things aren’t quite going to plan.” “The best part about working here is the friendly and supportive lab environment, where you can always count on others and never feel like you are asking too much.” “The best thing is friendly atmosphere and cooperation in our lab. It makes dealing with setbacks easier, celebrating successes even more pleasant, and keeps us motivated.” “The people—everyone is approachable, motivated, and genuinely passionate about their work”.
What’s there to do outside the lab?
Answers given by members of the lab in general include: “Dancing! Edinburgh has a vibrant community for various dancing styles (my pick is Latin dances). It’s amazing for meeting new friends and staying healthy.” “I like to go for walks in the Pentland Hills followed by a well-deserved beer in one of the many pubs.” “The Meadows is a great spot to unwind and soak in some greenery or a hike up Arthur’s seat offers stunning views of the city. Plus, the area is filled with great eateries, making it easy to grab a bite between experiments” “The Scottish Highlands and Islands are all within a half-day of travel. Fantastic if you enjoy epic scenery and being outdoors.” “Being based in the centre of Edinburgh is great – there’s usually lots going on, especially during the festival. Lots of nice green spaces close by is another positive.” “There is no shortage of historical, cultural, sporting, entertainment and foody places and events to explore in the heart of Scotland’s capital city. What makes it really special is that beaches, hills and the great outdoors are within very easy reach, whether you’re a thrill seeker or just want to chill.” “I love exploring Scotland, with its endless hikes and breathtaking scenery, though it is most enjoyable on the rare occasion when the weather is not cold and wet!” “The best place to go if you find yourself outside the lab is back inside the lab again!”
The Node is turning 15 this year. If you’ve ever visited the Node to read, write and interact with the global developmental and stem cell biology community – thank you for your support!
We would really appreciate any feedback you have about the Node, to make sure the community site is still relevant and useful for you, our community members.
Please spare around 5 minutes to fill in our survey.
This is part of the ‘Lab meeting’ series featuring developmental and stem cell biology labs around the world.
Where is the lab?
Li-Kun: My lab is located in Kobe, Japan. My lab initially belonged to RIKEN Center for Developmental Biology, which subsequently reformed to become the RIKEN Center for Biosystems Dynamics Research.
Li-Kun: My lab aims to understand how blood vessels are built and shaped into a hierarchical tubular network of arteries, veins and capillaries of optimal connections and size. We are particularly interested in endothelial cell mechanobiology – how physical forces and mechanical properties govern their shapes and behaviours to drive distinct steps of vessel morphogenesis, from sprouting angiogenesis to vessel remodelling. We are also keen to elucidate the interplay between endothelial cells and the perivascular environment such as haemodynamic forces (shear stress and pressure) at the apical surface and mural cells on the abluminal surface. In the long term, we aim to uncover whether altered endothelial cell mechanobiology contributes to endothelial dysfunction and vascular anamolies. To address these questions, we employ a spectrum of methodologies such as zebrafish genetics, high resolution time-lapse confocal microscopy, optogenetics, pharmacology, quantitative image analyses, scRNA sequencing and mathematical modelling.

Lab roll call
Li-Kun Phng: We are an internationally diverse lab, and the current lab members are listed from oldest to newest here.
Emi Taniguchi: I have been a lab assistant since 2016. I am doing administrative work and zebrafish system care in the lab. Also, I check the condition of our zebrafish daily to keep them healthy.
Igor Kondrychyn: I am a Research Scientist and am currently working on a project investigating the role of aquaporins in embryonic hematopoiesis.
Yan Chen: I am a postdoctoral researcher investigating vascular remodelling during zebrafish development, with a focus on how endothelial cells regulate vessel size and structure. My research explores how endothelial cells undergo rearrangement and shape changes, particularly through actin-driven constriction, to fine-tune vessel dimensions. Using zebrafish models, molecular genetics, and live imaging, I aim to uncover the cellular mechanisms underlying vascular remodelling.
Haymar Wint: I am a postdoctoral researcher, and my research interest lies in investigating the role of microtubules in mediating endothelial cell responses to fluid shear stress, unveiling its role in vascular development and remodeling.
Mingzhao Hu: I am a PhD student enrolled at the Department of Biological Sciences at Osaka University. I am interested in understanding how mural cells impact vascular remodeling using genetics and high-resolution time-lapse imaging.
Jason da Silva: I am a research technician. I carry out general lab duties and am working on creating knock-in zebrafish lines.
Rajrishi Kumar: As a technical staff member in the lab, I contribute to research on developmental biology and vascular morphogenesis, with a focus on sprouting angiogenesis and mechanobiology using zebrafish as a model organism. My work involves maintaining zebrafish lines, performing genotyping, and assisting with experiments that dive into the molecular and biophysical aspects of blood vessel formation. Along the way, my science toolbelt’s been getting a glow up with hands-on experience in genetic manipulation, molecular biology, and advanced imaging techniques.
Favourite technique, and why?
Li-Kun: Undoubtedly light microscopy – the higher the resolution the better – as it allows us to peer into the dynamics of vascular cell behaviour, enabling us to understand the process of vessel morphogenesis.
Apart from your own research, what are you most excited about in developmental and stem cell biology?
Li-Kun: I am presently fascinated with the growing prominence of ion channels, osmotic gradient and hydrostatic pressure in regulating tissue morphogenesis.
How do you approach managing your group and all the different tasks required in your job?
Li-Kun: My job entails juggling research, administrative work and some teaching. It was a steep learning curve starting my lab in Japan without knowing the language. Thankfully, I am lucky to have a very capable assistant who helps me deal with work-related matters in Japanese within and outside the institute, allowing me to focus on the science. A major goal is to provide a good research environment (in terms of infrastructure and opportunities) that is conducive to scientific excellence and efficiency. I firmly believe that communication is crucial not only in keeping up-to-date with scientific progress and shaping research direction, but also in identifying and tackling problems (be it scientific or personal) that surface. As such, I meet researchers every two weeks, encourage open communication in our weekly lab meetings and foster team spirit over meals and lab outings. I also like to enliven the lab atmosphere by hosting visitors from abroad, which at the same time promotes exchange of ideas and technology as well as fostering collaborations. Another important aspect of my job is to ensure that we stay abreast with current developments in our field and to disseminate our work to the scientific community. In Japan, the JSPS-funded ‘Mechanical Self-transformation of Living Systems’ consortium (https://multicellular-mechanics.org/research) has been a vital platform for networking with scientists in the fields of biomedical sciences, engineering and physics. Beyond Japan, I attend internationally conferences and meetings but this is limited by family commitments. The plus side is that I spend more time with my lab members to develop and complete projects!
What is the best thing about where you work?
LKP: Core funding from RIKEN! And being able to pursue curiosity-driven research.
EM: I enjoy working in multi-cultural environment with the members come from different countries. So far, I have met the lab members from 15 different countries.
IK: Friendly atmosphere.
YC: One of the best aspects of working in our lab is the supportive and collaborative environment. Communication flows easily within our team and across research groups. We also have access to an excellent microscopy facility, where the friendly staff provide invaluable support.
HW: One of the best things about working at RIKEN BDR is its highly international environment, where researchers from diverse countries come together to collaborate. And, our lab’s warm, supportive, and well-structured team environment accelerates scientific progress, and makes work both productive and enjoyable.
MH: I’m the only student in our lab, so that I often receive helpful suggestions and feedback from other members, who have full experience in this field.
JDS: Everyone is nice and the atmosphere is very relaxed.
RK: The best part? The people and the place. Sure, RIKEN’s state-of-the-art facilities and cutting-edge instruments are great for high quality research, but it’s the environment and community that make it truly exceptional. From lab members to admin staff, everyone is incredibly friendly, communicative, and genuinely helpful. And then there’s our team leader, high energy, inspiring, and somehow always present when you need a hand, a nudge, or a fresh perspective. Oh, and bonus points for the stunning sea view from the lunch area. Yes, science with a seaside vibe!
What’s there to do outside of the lab?
LKP: I would typically like to recharge my batteries by not doing anything, but this, unfortunately, is not possible because I have two young ones at home to entertain. Kobe is sandwiched between the mountain and the sea, and so we often venture to the beach or forests to appreciate nature. In Spring, we enjoy hanami (cherry blossom viewing); in Autumn, momijigari (viewing of the vibrant autumn colours of maple leaves); in Winter, warming ourselves up by going to onsen (hot springs). And of course, we love trying out new cafes and restaurants.
EM: I like to travel not only in Japan but also to other countries to learn about cultures and ideas created by each region that has original geographical and historical factors.
IK: Relaxing outdoors (if no rain), cycling and listening to music while drinking wine.
YC: Outside the lab, Japan offers a perfect blend of nature, culture, and city life. Depending on the season, I enjoy hiking in the nearby mountains, visiting historical temples and shrines, or exploring the diverse food options. There are also many festivals throughout the year, offering a chance to experience traditional culture. Within the lab, we often celebrate small victories, birthdays, and milestones with group dinners and relaxed afternoon tea gatherings.
HW: Outside the lab, I enjoy exploring Japan’s rich culture and natural beauty. I visit historical sites, experience seasonal festivals, and try different local foods. Sometimes, I join social gatherings with colleagues or participate in local events to experience Japanese traditions firsthand.
MH: Outside of the lab, we often have a food-themed adventure to explore the local food, from Ramen restaurant to open-air bar. I also spend time in nature to increase feelings of happiness and pay attention to the changing seasons. I really enjoy cherry blossom in spring and Momiji viewing in autumn!
JDS: Kobe is close to the sea and to mountains so there are a lot of scenic places to visit. There are hundreds of restaurants to try around Kobe too. It’s also easy to visit other cities in Japan by public transport.
RK: I am new to the area, but outside of the lab I usually go for a run or play basketball. Here in Kobe, there are great cafes, cozy izakayas, and lively karaoke spots where we can relax after a long day. The city is also surrounded by mountains, offering plenty of hiking spots with scenic views of both the city and the ocean. And of course, we are in Japan, a hub for shopping and entertainment, so there is always something to do. Also, if you are feeling too adventurous, there are plenty of options for onsens to enjoy a hot spring experience.

In this ‘Featured image’ post, we find out more about the story behind Allan Carrillo-Baltodano’s image, which was one of the runners-up in the competition.
Dancing actinotroch Allan Carillo-Baltodano Actinotroch larva of a phoronid worm with phalloidin shown in yellow and acetylated tubulin in magenta. Imaged with a Zeiss LSM 800 at 10 x magnification.
What is your background?
I did my undergrad at the University of Costa Rica, in Costa Rica. Early on, I biased my interests towards invertebrate zoology, and ended up doing an undergrad thesis on marine zooplankton of coral reefs. It was back then when I saw the beauty of marine invertebrate larvae. I have been studying evolution and development (EvoDevo) of marine invertebrates since — first, during my PhD in Néva Meyer’s lab at Clark University in Massachusetts (USA), and currently as a postdoc in Chema Martín-Durán’s lab at Queen Mary University of London in UK.
What are you currently working on?
I study how body plans of marine annelids develop, and try to understand how different modes of development in these and other animals could have evolved.
Can you tell us more about the story behind the image that you submitted to the image competition?
The image shows a larva of a phoronid worm. The larva is commonly known as actinotroch, and it is very conspicuous among other members of the zooplankton community because of the tentacles surrounding the head. To swim the larva propels itself using cilia (shown in the image in magenta) concentrated in a ciliary band on the posterior part of the larva. The big hoodie you see at the top will open slightly so that food can be captured in the mouth. One of the wonderful things of the plankton is that if you are lucky, you can find any stage of development of these and many other amazingly weird invertebrates.
What is your favourite technique?
I like mostly confocal microscopy, although if a sample is nice enough, you can get some very beautiful images with DIC microscopy as well.
What excites you the most in the field of developmental and stem cell biology?
The breakthrough in technologies has really opened the door for many of us who like to study development in unusual research organisms. In combination with the EvoDevo field being more open and the growing interest in comparative biology across many species and many scales, we are creating a great environment for anyone to make new discoveries.

In this ‘Featured image’ post, we find out more about the story behind Julia Peloggia de Castro’s image, which was one of the runners-up in the competition.
Who’s active? The image depicts a zebrafish embryo at 9 hours post-fertilisation on a lateral view. Cells are stained with MitoTracker, which labels active mitochondria, and cell membranes are labelled in cyan with a EGFP transgenic membrane tag. Image was taken using a 20x objective on a spinning disk confocal microscope.
What is your background?
I got my bachelor’s degree at the University of São Paulo, in Brazil. I majored in Biological Sciences with a focus on genetics and molecular biology. I then pursued my PhD at the Stowers Institute for Medical Research in Kansas City (USA), where I studied zebrafish development and phenotypic plasticity under the mentorship of Dr. Tatjana Piotrowski. I am now a postdoctoral fellow at University of California, Los Angeles (USA) working with Dr. Heather Christofk.
What are you currently working on?
My current interests are in developmental metabolism, and how maternal metabolic states impact mouse embryonic development.
Can you tell us more about the story behind the image that you submitted to the image competition?
This image shows a zebrafish embryo after a few hours of development. One of my favorite things about zebrafish is how fast they develop, giving us the opportunity to watch it —and image it— in real time. This particular image was taken late at night in the laboratory while I was testing a reagent and optimizing imaging parameters before running a larger experiment later that week. The result was definitely worth staying late for!
What is your favourite technique?
I really appreciate any type of microscopy. From the foldscopes to confocal and electron microscopes. Looking at cells never gets old!
What excites you the most in the field of developmental and stem cell biology?
I think this is a very exciting moment in developmental biology research. The last decade has brought many technical revolutions and more fields are bridging towards developmental biology, generating new questions and new ways to approach them. This makes me think we are poised to discover new biological principles soon.
