Human neural crest (NC) cells are the precursors for a wide range of ectodermal and mesenchymal cell derivatives. Due to the inherent difficulties associated with early human embryonic studies, it is currently unclear exactly when NC cells are specified and from what. Differentiation of human embryonic stem cells represents an excellent in vitro system to study NC induction; however, current protocols often involve cell conglomerates and/or undefined media, making it difficult to tease apart the key signalling events that drive induction. Now, on p. 398, Martín García-Castro and colleagues report a highly efficient, defined protocol for human NC induction and use this system to identify a population of cells, which they call ʻpre-neural plate borderʼ cells, that represent the earliest known stage of NC specification. WNT-induced molecular markers are used to characterise this population, which the authors show is specified distinct from ectoderm and mesodermal fates. The authors further...
The Company of Biologists Workshops
For the last 15 years, our publisher, The Company of Biologists, has provided an apt environment to inspire biology and support biologists through our Workshops series. Read about the evolution of the Workshop series and revisit JEB's experience with hosting the first Global South Workshop.
Call for papers – Lifelong Development: the Maintenance, Regeneration and Plasticity of Tissues
Development invites you to submit your latest research to our upcoming special issue – Lifelong Development: the Maintenance, Regeneration and Plasticity of Tissues. This issue will be coordinated by Guest Editors Meritxell Huch (Max Planck Institute of Molecular Cell Biology and Genetics, Germany) and Mansi Srivastava (Harvard University and Museum of Comparative Zoology, USA), working alongside our team of academic Editors. Submit your articles by 30 May 2025.
Meet our 2025 Pathway to Independence (PI) fellows
We are delighted to announce our third cohort of PI fellows - researchers whom we will be supporting as they transition from postdoc to Principal Investigator. Read about the eight talented fellows chosen, whom we're excited to be working with as they navigate the job market.
A case for broadening our view of mechanism in developmental biology
In this Perspective, B. Duygu Özpolat and colleagues survey researchers on their views on what it takes to infer mechanism in developmental biology. They examine what factors shape our idea of what we mean by ‘mechanism’ and suggest a path forward that embraces a broad outlook on the diversity of studies that advance knowledge in our field.
