WebOct 1, 2000 · Even though Shh can induce all ventral cell types, the generation of certain sets of interneurons in the dorsal-most region of the ventral neural tube does not depend on Shh signalling 29. WebIn particular, the notochord is able to induce the differentiation of the floor plate (fp), and they both represent a continuing source of ventralizing signals within the neural tube. The notochord is also important for somite differentiation, where Shh concentration gradients differentially pattern dorsal–ventral somitic fates.
