A new year is a good opportunity to look back on the one just passed, and whether you’re a Node regular or new to us, this selection of our 2019 highlights will hopefully be of interest, particularly if you’re interested in contributing something and looking for inspiration. We are a community site for and by developmental biologists – it’s free and easy to post, just sign up here. And if you don’t already, be sure to follow us on Twitter and Facebook. Happy new year!
Top 5 most-read posts published in 2019
Congratulations to Joachim Goedhart (twice, and for the second year in a row) and Shinichi Morita for making our top 5 most-read articles this year.
We love to hear the stories behind the latest papers – these might be personal recollections or more data-focused, and can take advantage of our informality and lack of word limit. Here’s ten of my favourites from 2019:
We’re now up to 42 in the series (Arabidopsis, Ascidian, Axolotl, Bat, Butterfly, C. elegans, Capitella, Chicken, Cnidaria, Colonial tunicate, Coral, Cricket, Ctenophore, Drosophila, ES cells, Gar, Gecko, Honeybee, Hydractinia, Lamprey, Larval-microbe, Maize, Marchantia, Mayfly, Moss, Mouse, Oikopleura, Onychophoran, Parhyale, Planaria, Platynereis, Rhino beetle, Sea urchin, Shark, Siphonophore, Skate, Spider, Sponge, Termite, Turtle, Xenopus, Zebrafish). Is your model missing? Get in touch.
Art and science
Annabel’s cover image
In March we posted a fascinating account from an artist (Gemma Anderson, University of Exeter) and a cultural historian of science (Janina Wellmann, MECS, Leuphana University Lüneburg) who visited the EMBL. Their outsider perspective on how science is done is well worth the read.
In October we interviewed Annabel Ebbing (the Hubrecht Institute in The Netherlands), first author of a Development paper on C. elegans neuroblast migration. She designed a beautiful piece of worm art that made Development’s cover – we heard about what science and art meant to her.
Science on tour
We published many meeting, workshop and course reports this year:
JanuaryThe launch of the Node Network, a global directory of developmental and stem cell biologists. You may have filled out our survey in the summer – the site is nearly there now and we’d love as many people as possible to sign up for it.
March(ish)We will run a community survey all about the Node. What can we do better in the coming years? What type of content do you want to see more (or less) of? What are we missing? Look our for our survey early in the year.
April Cast your mind back to April 1st, 2010 – Gordon Brown was UK Prime Minister, Clash of the Titans (eh?) topped the cinema charts, atmospheric carbon dioxide was 389ppm…and the Node was launched, publishing its first post (the first of 2403 and counting). Ten years on and it’ll be a good time to reflect on the past and look forward to the future. We’ll probably have some cake in the office and metaphorical cake on Twitter!
Department/Location: Wellcome Trust-Medical Research Council Stem Cell Institute

A postdoctoral Research Associate position is currently available for an individual to work in the laboratory of Prof. Anna Philpott within the Cambridge Stem Cell Institute (https://www.stemcells.cam.ac.uk/research/pis/philpott). The Philpott lab has broad interests in understanding the fundamental mechanisms that determine cell fate choice and differentiation during embryonic development and in cancers, as well as how these processes are co-ordinated with cell cycle progression.
The successful candidate will undertake a project focused around transcriptional regulation of lineage fidelity during fate specification and differentiation of mouse embryonic stem cells, focusing on uncovering epigenetic and co-factor-dependent mechanisms underlying these processes. There is also an opportunity to work on parallel mechanisms of fate specification and differentiation in Xenopus embryos. Within the laboratory, we use several experimental systems including mammalian embryonic stem cells, cancer cell culture, organoid systems as well as embryos of the frog Xenopus laevis. We use many techniques including genome-wide analysis of gene expression in single and multiple cells, chromatin binding and accessibility studies and crispr genome editing, alongside diverse biochemical approaches.
The successful candidate will have a PhD, considerable experience in stem cell biology, epigenetics, molecular biology, developmental biology, or a similar field, and a proven track record in scientific publication. Prior experience in mammalian cell culture is essential. Experience of epigenetics and/or transcriptional regulation are essential, while experience of genome-wide transcriptional analysis, and in particular analysis at the single cell level, would also be an advantage. Applicants must display an ability to undertake project management, work within a multi-disciplinary team environment, have good presentation and communication skills and the ability to contribute to an environment supporting researchers at all stages of their careers.
The Wellcome – MRC Cambridge Stem Cell Institute (CSCI) is a world-leading centre for stem cell research with the mission to transform human health through a deep understanding of stem cell biology. https://www.stemcells.cam.ac.uk/ . CSCI moved to the brand new, state of the art Jeffrey Cheah Biomedical Centre building on the Cambridge Biomedical Campus in summer 2019. The University actively supports equality, diversity and inclusion and encourages applications from all sections of society.
A 3-years-PhD position is available at the Chédotal Lab at the Vision Institute in Paris.
The goal of the PhD project will be to describe the organization of the developing human eye and characterize molecular and cellular mechanisms underlying human retinogenesis. We propose to revisit eye formation combining modern and innovative single-cell molecular and 3D imaging approaches on human embryo/fetal eye samples. Data from light sheet fluorescent microscopy (LSFM), spatial transcriptomics and in situ sequencing will be incorporated into one scaffold to provide a comprehensive 3D map of human retinogenesis. The project will provide significant and detailed insights into human ophthalmology, generating the first reference map of human retina development. It will further contribute to the Human Cell Atlas initiative. The thesis will be directed by Dr Alain Chédotal.
An experience in bioinformatics and transcriptomics or 3D imaging would be a plus but is not required.
Candidates should hold a diploma or a master’s degree in Neuroscience, Developmental Biology, Microscopy or Bioinformatics
They may send their application (in a PDF-format) to Dr Alain Chédotal (alain.chedotal@inserm.fr), including a CV and contact information for two references.

Charles Darwin’s famous finches from the Galapagos Islands
In this episode of Genetics Unzipped Kat Arney explores the myths and misconceptions behind two of the most iconic images in evolutionary biology: the much-parodied March of Progress – a series of human ancestors walking across the page, portraying the inexorable journey from monkey to man – and the famous finches of the Galapagos islands, which are supposedly the inspiration for Charles Darwin’s theory of natural selection.
Where did these infamous images come from, and do they really show what everyone seems to think they do?

The Lyons Lab at Scripps Institution of Oceanography (a department at U.C. San Diego) is recruiting a full-time Postdoctoral Scholar to support research projects funded by an NIH MIRA award. The Lyons Lab (www.lyonslab.org) focuses on cell type differentiation and morphogenesis with a particular interest in how these processes evolve. The postdoc will contribute to our lab’s goal to build the first comprehensive developmental gene regulatory networks (GRN) controlling early events in molluscan development (e.g. germ-layer segregation, organizer signaling, and gastrulation). GRN analysis (both experimental and synthetic) will be carried out in the marine slipper snail Crepidula. The postdoc can take advantage of a growing tool kit for functional genomics in Crepidula, as well as a new marine transgenics facility for maintenance of stable lines. In collaboration with Dr. Lyons the postdoc will be responsible for leading an independent project of mutual interest that aligns with the postdoc’s career goals.
The postdoc will join a motivated group of students, staff, and postdocs who are broadly interested in cell and developmental biology of marine organisms. Additionally, the Lyons Lab offers a broad range of other systems for comparative developmental studies among molluscs and echinoderms, and provides a highly interdisciplinary and collaborative environment within our group, and with other labs at the Scripps Institution of Oceanography (https://scripps.ucsd.edu/), with U.C. San Diego’s main campus (https://ucsd.edu/), and with other institutions in the greater San Diego Area.

A 2 year post-doctoral position is available starting early 2020 to study transcriptional control of neurogenesis in Xenopus and mouse. The research will be conducted in the laboratory of Developmental Genetics (http://gendev.ulb.ac.be/bellefroidlab/) of the Université Libre de Bruxelles (ULB) Neuroscience Institute (UNI) (https://uni.ulb.ac.be/) in Gosselies (30 km south of Brussels).
Balancing neural progenitor cell (NPC) self-renewal and neuronal differentiation is essential for generating cells in correct numbers and diverse types during neural development. As such, neurogenesis is tightly regulated by a complex array of transcription factors that work in concert to coordinate NPC maintenance, proliferation and differentiation. Our focus is on the Dmrt3 and Dmrt5 transcription factors that we have identified as critical regulators of cortex development and on Prdm12 that we found to be required for the development of pain-sensing neurons.
Our aim is to better understand how these transcriptional regulators function in vivo by identifying genome wide their direct targets and interacting partners. As most remains to be discovered about the mechanism of action of these transcription regulators, results of this project should uncover novel essential aspects of corticogenesis and nociceptor development and functioning.
We are looking for highly motivated candidates with an experience in mouse genetics, cell and molecular biology techniques (ChIP-seq, RNA-seq, AP-MS,…) and preferentially a background in neuroscience. Interested candidates should send a letter of motivation (before end of February) describing past research experiences and full CV to:
Eric Bellefroid (ebellefr@ulb.ac.be), together with the name and e-mail address of 2 references.
