During organogenesis, Sonic hedgehog (Shh) possesses dual functions: Shh emanating from midline structures regulates the placing of bilateral structures at early stages, whereas organ-specific Shh locally regulates organ morphogenesis at later phases. rules of the number and position of MTs. Lineage analysis of hedgehog (Hh)-responsive cells, and analysis of gene manifestation in KO embryos suggested… Continue reading During organogenesis, Sonic hedgehog (Shh) possesses dual functions: Shh emanating from
