WebSonic hedgehog (Shh) is required for the induction of ventral cell types along the dorsal–ventral axis of the entire neural tube. To induce several distinct cell types, Shh functions as a morphogen; distinct cell types are induced at specific concentrations of Shh, which is distributed as a gradient away from its sites of synthesis, the ... WebThe sonic hedgehog (SHH)–patched (PTCH) pathway functions in normal embryonic development of the brain, musculoskeletal system, and hair follicles, and in normal post-natal control of hair follicles. Dysregulation of the pathway has been implicated in a variety of neoplasias, including those of skin and brain. Based on the knowledge that generalized, …
