1. What is the neural crest? Where does it arise? What is the role of EMT in neural crest cell (NCC) formation? ANSWER: The neural crest is where our neural tube forms from the neural crest arises from the ectoderm and gives rise to peripheral nervous system 2. Briefly explain the relationship of BMP and Shh signaling to NCC specification; what critical TFs do NCCs express? Why do those TFs matter? ANSWER: Neural Crest is specified at a moderate level of bmp signaling at low end (=ne...
