Embryonic stem (ES) cell lines have provided very useful models to analyse differentiation processes. We present here the development of a differentiation system using ES-like cell lines from medaka. These cells were transfected with the melanocyte specific isoform of the microphtalmia-related transcription factor (Mitf). Mitf is a basic helix-loop-helix-leucine zipper transcription factor whose M isoform is restricted to neural crest derived melanocytes and is essential for the development of these cells in vertebrates from mammals to fish. What is not clear yet is whether Mitf is a downstream factor or a master regulator of melanocyte commitment and differentiation. Expression of Mitf in the ES-like cells from medaka led to the induction of cells that, by morphology, physiology and gene expression pattern, were confirmed to be fully differentiated pigment cells. Mitf expression is therefore sufficient for the proper differentiation of medaka pluripotent stem cells into melanocytes.
Development presents…
Development is delighted to host a webinar series showcasing the latest developmental biology and stem cell research. The webinars are held each month with talks from postdocs applying for independent positions as part of our Pathway to Independence programme. Visit Development presents... on the Node to see which stimulating topics are coming up in the next few months.
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.
