Meeting report- 2023 Young Embryologist Network Conference 

Posted by , on 12 June 2023

By Ioakeim (Makis) Ampartzidis, Courtney Lancaster, Danielle Liptrot, and Rosie Marshall

Happy Birthday YEN! 

The Young Embryologist Network (YEN) turns 15 this year. YEN serves as a vibrant platform for knowledge exchange and collaboration, with a particular emphasis on showcasing the work of early career researchers (ECRs — postdocs and PhD students). It has been 15 years full of inspiring science and what better way to celebrate than with a debrief of this year’s fantastic conference: 

Hot Off the Press: Scientific Talks

Pre- and peri-implantation development was a particular focus in the scientific talks this year, highlighting the drive to improve in vitro embryo work relating to fertility. Two of the invited speakers presented impressive work on the subject: Katsuhiko Hayashi from Osaka University kicked off the day with an impressive overview of his ground-breaking work on reconstructing oogenesis from pluripotent stem cells, which he hopes will be used to save the endangered Northern White Rhino (only two females of this species remain); Andrea Pauli from the Institute of Molecular Pathology in Austria later showed us her fascinating work on how closely related species prevent interspecies fertilisation (in the case of zebra- and medaka-fish, it’s just one protein expressed on the egg!)  

Many of the selected talks also focused on these early stages of development: Chloe He showed us how deep learning and non-invasive imaging of cleavage-stage human embryos can help us to study how cell arrangement affects blastocyst quality; Johanna Gasler demonstrated the requirement of orphan nuclear receptors on early development and zygotic genome activation in murine embryos; Lessley Sepulveda-Rincon produced apoptosis-deficient primordial germ cells in mouse chimeras to understand their functional incorporation to the mouse embryo; Zukai Liu presented the specification of extra-embryonic mesenchyme in primate development, at a genome level revealing ape-specific attributes.

Once again, YEN showcased the wide range of fascinating organisms used in developmental biology research. Michael Emmerson revealed how zebra finches can detect sound cues to alter their growth rate in utero (including expert impressions of zebra finch heat calls)! The utility of the old favourite Drosophila was once again on show, with Gloria Jansen’s impressive talk on how paternally inherited transposable elements alter penetrance of germ cell loss. O. fusiformis, a bilaterally symmetrical organism, is another neat model on which Allan Carrillo-Baltodano studies dorso-ventral patterning. Finally, zebrafish once again lived up to its reputation as a beautiful model for imaging, with Agatha Ribeiro da Silva utilising the model to study endothelial cell migration defects in heart development. 

Wrapping up the short talks was the final invited speaker, Laura Pellegrini. She is a current postdoc in Madeline Lancaster’s lab who is soon moving to King’s College London to start her own group. She showed us how choroid plexus organoids have a wide range of applications, from a drug screening system to test whether drugs can cross the blood-CSF barrier, to a model for studying viral infection of the brain. Certainly ground-breaking work and we look forward to seeing how her group progresses! 

Sammy Lee Memorial Lecture

The final talk of the day was the Sammy Lee Memorial Lecture, which was established to remember Sammy and to reflect on his contributions to developmental biology and his passion for inspiring the next generation of scientists.

Sammy was a visiting professor in Cell and Developmental Biology at University College London (UCL), whose life-changing work was responsible for outstanding advancements in reproductive health and fertility. Sammy started his scientific journey with a PhD at UCL, where he was working on nerve muscle interaction. Not long afterwards, Sammy became interested in developmental biology. This led to his work on gap junctions in mammalian embryos where he discovered a link between gap junction communication and early embryonic development. He then became a clinical embryologist in 1985, helping to perform some of the UKs first egg donations, before being appointed as the scientific director of the Wellington IVF department. Sammy’s team was the first in the UK to perform gamete intrafallopian transfer (GIFT), pioneered a method of mechanical assisted hatching in the UK to improve chances of in utero implantation and produced the world’s first virus free ICSI (intra-cytoplasmic sperm injection) baby to a HIV discordant couple.  

Fitting with Sammy’s character, the Sammy Lee Memorial Lecture was delivered by Henrik Kaessmann who entertained us with the wonders of sex chromosomes. He drew our attention to the small size of the Y chromosome which has a striking feature of chromosome wide gene decay. He then discussed gene dosage across different evolutionary lineages from mammals to birds.

It was Sammy’s wish to present a medal to a young developmental biologist on the merit of scientific communication and outstanding research. The 2023 Sammy Lee medal for best short talk was awarded to Clara Munger, who impressed the judges with her presentation about marmoset amnion specification. She told us about her work using marmoset embryonic stem cells to make spheroids in a microgel culture system, and how this system can be used to interrogate signalling pathways required for lineage specification in the post-implantation embryo. The runner-up went to a fantastic talk from Ashley Libby who discussed progenitor cell dynamics and gene regulatory networks during neural tube development.

Poster Sessions

First poster session of the day.

The day was split up by two fantastic poster sessions in the morning and afternoon, with over 30 posters being presented both in person and online. The topics ranged from sea urchin larval skeletogenesis to the identification of unwanted genetic variants in stem cell populations, having implications in evolution, developmental biology and regenerative medicine. In addition, it was excellent to see projects being presented from a range of early career researchers, from master’s students to senior postdocs. The diversity in presenters and topics incited long discussions in both poster sessions, making it difficult to coax everyone back to their seats. It will certainly be exciting to see what collaborations were spawned in these sessions, and how it will influence the direction of developmental research in years to come. 

With all the excellent projects being presented, it was surely a hard decision for the judges to award the poster prize and runner up. That being said, on observing the work of prize winner – Francisco Manuel Martin-Zamora – and runner up – Adiyant Lamba – it is evident their projects are both deserving of recognition. Francisco, a PhD student at Queen Mary University, presented his work on how epigenetics may underpin temporal shifts in the diversification of larval and bilaterian life cycles. Adiyant, also a PhD student based at the University of Cambridge, described the heterogeneities which influence early cell fate decisions between the inner cell mass and the trophoectoderm. The future of these two young embryologists is very bright! 

Perspectives: EDI Awareness in Academia 

A refreshing addition to the science-rich day was the addition of scientific perspective sessions, introduced by the committee in 2022. This year, the focus was on Equity, Diversity, and Inclusion (EDI) in science, raising awareness for the importance of embracing EDI in scientific meetings.  

This year’s perspective experts Alison Forbes, Head of Inclusion at The Francis Crick Institute in London, UK, and Rafael Galupa, a social entrepreneur and group leader at the Centre for Integrative Biology in Toulouse, France, shared their valuable perspectives on the topic. They focussed on the current state of underrepresentation in science and offered practical strategies to enhance inclusivity. When asked how ECRs can realistically improve diversity, Alison suggested to “[…] start with self-education. Read some books and listen to podcasts;” while Rafael encouraged us all to “[…] find a way to contribute that is aligned with their personality and availability”. By prioritizing EDI in scientific meetings, we collectively advance knowledge and ensure that the science we all love and care about reflects the full spectrum of human perspectives and capabilities. For a more in-depth conversation on this topic, read this interview with Alison and Rafael. 

The faces behind YEN 2023

A big shout-out to the organising committee of YEN Conference 2023, for their hard work, fresh ideas, and organising skills. This year’s chairs Foteini and Jeremie along with the fantastic team of Michelle, Sergio, Jack, Ollie, Luca, Ferran, Olivia, Oliver, Matyas, Jesus, Mint, Claudia, Irina, and Christos, celebrated the 15th birthday of Young Embryology Network with a memorable Conference. The team is composed mainly from PhD students and ECRs based in London and if you like to learn more about their journey follow them on twitter @YEN_community.

Made the Same Way: Where’s the line, where’s the limit?

Posted by , on 2 June 2023

The seventh episode of Made the Same Way, a podcast produced by the Wellcome-funded Human Developmental Biology Initiative, features sociologist and writer Marieke Bigg discussing the ethics of research with early human embryos with Mancunian poet and rapper Meduulla. The pair discuss the legacy of Anne McLaren and muse on future implications of this area of research.

At the end of the episode, the pair collaborate on an original piece of music inspired by their conversation.

“What things can we consider to be right and wrong, and who makes that decision?”

– Meduulla

About the participants

Marieke Bigg writes about bodies and culture. She holds a PhD in Sociology from the University of Cambridge, where she studied the technological transformation of human reproduction, with a focus on Dr Anne McLaren’s role in the human embryo research debates. She now writes both non-fiction and fiction about the cultural dimensions of biology and bodies. In addition to her books, Marieke writes freelance, hosts podcasts and panels, and collaborates with scientists and biologists to discuss and produce art that conjures new social worlds.

Check out some of Marieke’s writing here:

Current Fiction: WAITING FOR TED (Dead Ink Books, Oct 2022)

Upcoming Non-Fiction: THIS WON’T HURT (Hodder, Feb 2023)

Hailing from North Manchester, Meduulla is a 23 year old Zimbabwean-born Rapper, Poet and DJ paving her way through the UK rap scene. Meduulla marries her modern flows and witty lyrics with jazz inspired hip hop instrumentals to create music that reflects the present day whilst carrying a nostalgic air.

Despite having been a writer for 10 years, she only released her first single in 2021 which then led to her appearance on BBC’s The Rap Game UK as a finalist.  Her independently released single, Mish Muulla was selected as Track of the Week on BBC 1Xtra Radio, resulting in Meduulla performing at Reading and Leeds Festival in 2022. The wordsmith is a 2023 Sound and Music Seed Award recipient and her poetry won first prize in TogetherintheUK’s migrant writers competition. Her passion for using her lyricism as a force of positive change continues to be recognised by various cultural organisations.

In 2023, Meduulla will release her debut project entitled Oblongata.

You are not alone

Posted by , on 2 June 2023

Gender problems in STEM are familiar to women researchers in every corner of the world. Japan is no exception. In a culture that seeks harmony and balance with people around, where conflict is avoided at all costs, it is often difficult to express someone’s needs. Social pressure is working in very subtle ways. You have an event in a room with photos of the previous heads of the department, twenty or thirty of them, which are all men; you go to a conference and see the overwhelming majority of the keynote speakers being male researchers; you notice the appointed leaders of the diversity and inclusion groups are mostly male when the volunteer groups have hardly any. The hours researchers stay in the laboratory make you feel like you are reliving the same day again and again; the boisterous communication style and jokes and comments are too harsh for you. The passion you once had for research is slowly withering away, leaving you with the feeling of unhappiness and unworthiness, and you give up, thinking that you are not made for this work, you are not a good fit, with a question in your mind: “How did I end up here?”.

In centre of the picture there is a girl who is just graduated a university and is still wearing her graduation ceremony attire. She is looking on the row of photos of department chairs, who are all male. And is thinking about how she is fitting into the picture.

I was lucky to grow up in a bubble where science was never gendered, there were no sciences that were inherently for women or men, and there were no subjects that some genders were naturally bad at. My parents were working in science-related areas, and they would divide school subjects between them. My mother would help me with mathematics, chemistry, and biology. My father with English, physics, and music. So, it never occurred to me that there was a need for societies supporting women researchers until I moved to Japan. My intrinsic belief that science is for everyone was challenged by a different culture, where many people of both genders believed otherwise for one reason or another. The confusion and frustration led me to research the problem (what else a scientist can do!?). And what I discovered – amazed me.

The universities in Europe and North America have women in STEM organisations active on social media, organising events, inviting young women scientists, actively connecting, and searching for opportunities to widen the network. These societies are vocal and visible, making the world know they exist. They constantly push for change. There are university-based workshops, training programs, and symposiums specifically for women in research. There is this feeling of women researchers trying to unite and support each other, pave the way for future generations, and improve the working environment.

I wished something like this existed in Japan. Most of the groups I found were quite exclusive: only for students, or mainly in Japanese, with no easily accessible information on how to join and what kind of events they are planning. There was little presence on social media, and you would need to make a targeted search to find them. I rarely hear about women researchers-oriented events or workshops, and yet to hear about women researcher-oriented training university programs.

So, I searched for women researchers’ communities outside the university and found ‘’Women in Science Japan’’, the young community founded by Elizabeth Oda, Dr. Sarah K. Abe and Lauren Hartz in 2019. I looked through their website and joined on the spot. I had a chance to talk with one of the co-founders, Elizabeth, and asked her about the motivation behind creating “Women in Science Japan”:

I and my co-founders created this community to address what we have witnessed as gender inequality in Japan, both the statistics you can often hear in the media and micro- and macroaggressions women experience. We also wanted to start with students and give a voice to students in high schools and universities. Because we knew both from the literature and from our own experience that in Japan, there are many negative stereotypes around women pursuing STEM and girls are discouraged from pursuing these fields from the young age.

Elizabeth says that one of the reasons most people join “Women in Science Japan”, and the one she thinks is very important for the future of the community and hopes to improve – is a mentorship program. That was one of my reasons for joining too. Even without talking about being an international researcher in a country that doesn’t speak your native language and has completely different social structures, finding your way in a field that wasn’t designed for you is difficult. I often feel that mentoring comes naturally to male researchers, whereas women researchers need it even more but receive it very rarely and are expected to figure out many things on their own. The community evolved, and apart from students, it started to focus more on early-career women. Elizabeth notes that it was important to create a space where members can be vulnerable, authentic, and empowered, without the fear of retribution, discipline or ostracisation, to feel heard and to have someone else say, “You are experiencing that too? I thought it was just me.”

The reality is that gender inequality is a systemic problem that an individual person can’t solve, so the idea was to create a culture that is more aware of the issues, willing to discuss the issues, face the issues, and hopefully raise these issues outside of the Women in Science Japan community.

Women in Science Japan now unites scientists, educators, women working in start-ups and the corporate world, and students at high schools and universities. Geology, biology, engineering, IT – all fields of science are welcome. And it is beautiful. It is invigorating to have such diversity, to be with people from all walks of life, with different backgrounds and different life stories. It is empowering and inspiring to hear what fellow members have overcome and where they are heading. It is not easy to be vulnerable and share your story, but if the person decides to do it – it is a treasure, a path for growth for both the person sharing and the person listening.

Women in Science Japan offers various activities: career-related events, mentorship mentioned earlier, casual events, and the book club (!). Elizabeth says that the book club is one of the things she is proud of. The book is chosen by members interested in joining the club and is related to gender inequality, science, and Japan. Currently, the book club is reading “How to Be an Inclusive Leader: Your Role in Creating Cultures of Belonging Where Everyone Can Thrive” by Jennifer Brown, which touches on diversity, equity, and inclusion. Being a part of the book club is a fantastic experience for me. The same text often generates different responses in different people, and this experience is the diversity in action. It is eye-opening to hear what people think and how the same words are heard differently because of the different backgrounds. Reading the book together, rather than alone, creates deep conversations, challenges to see the text from different angles and helps to navigate difficult questions.

I think we can only overcome our hardships and glass ceilings by holding each other’s hands and supporting and helping each other. This is one of the things Women in Science Japan is trying to achieve, a support system to help members to navigate complicated work situations or decisions, get feedback, provide clarity about career paths, and create a network that helps to build their businesses or solve work-related problems, or for international members to settle in Japan. And I wanted to use my chances to speak to the world and encourage women researchers to unite, to join communities like “Women in Science Japan”, to create new communities of like-minded people, say for women scientists in developmental biology or tissue engineering, or working on a specific problem. To be visible, vocal, advocate for your needs, become more confident, and create a welcoming future for the new generations of women in science. Or make a safe space for sharing your thoughts, finding your way, and knowing that you are not alone.

Five silhouettes of women, each one represents a different group of women, each of them is holding a sign. Signs are: smart, ambitious, our future, love science, a leader. In the centre it is written: 'You are not alone'.

You are very welcome to join “Women in Science Japan” if you are currently working in science-related areas in Japan.

But if you are in countries other than Japan, here are some links that can get you started on your journey of finding a safe space. (Thank you to my fellow correspondents, The Node community manager, and my friends for helping me with this list.)

* Thank you to my friend Monica for the advice on illustrations.

In sixth episode of HDBI’s podcast, Made the Same Way, scientist Katie Long explores the topic of human brain development with spoken word artist Harmony.

At the end of the episode, Harmony creates an original spoken word piece based on their conversation.

If we look at every single person’s brain, most of these wrinkles will be in the same place.”

-Katie Long

About the participants

Katie’s lab has been at King’s College London since 2019, and their research focuses on how the human neocortex develops with the correct size, shape and organisation. To address this they use an interdisciplinary approach using human fetal cortex tissue models to look at the cellular and mechanical mechanisms that drive the development of the human neocortex, including the formation of the folds present on the surface of the neocortex, and how dysregulation of these functions can lead to neurodevelopmental disorders. They also use our human fetal tissue culture models to investigate the effect of injury on the developing human brain.

In her spare time, Katie likes to get outdoors and she is a keen cyclist and runner.

Harmony is a spoken word artist who has been interested in the arts since she watched her first movie.
