The mammalian salivary gland is a valuable model for analysis of the morphogenetic and differentiation events that occur during branching morphogenesis of organs. Following a period of growth and branching, epithelial cells of the salivary gland differentiate down ductal or acinar routes. What are the signalling mechanisms that control morphogenesis, differentiation and lineage choice, and how are these processes coordinated to ensure appropriate size and composition of the final organ? The FGF pathway is known to play key roles in salivary gland development, including via the activation of KIT signalling – which promotes the expansion of distal (future acinar) progenitors. Moreover, WNT signalling has been implicated in salivary gland morphogenesis, although its function is unclear. On p. 2311, Akira Kikuchi and colleagues use genetic and pharmacological approaches, both in vivo and in vitro, to demonstrate that mesenchymally derived WNT signals inhibit acinar differentiation and maintain end bud cells...
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.
