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. WebJul 24, 2024 · In our zebrafish model, overexpressing of N1aICD specifically in osteoblasts induced high bone density and caused thicker spinal bones and narrower neural/hemal canals in a gender-specific manner.
