Hedgehog Signaling Pathway in Invertebrates | Mechanism and Role in Development

The video tutorial explains the role of hedgehog proteins in invertebrates, focusing on their involvement in embryological development, cell patterning, and differentiation. It introduces the concept of graded signaling, where different concentrations of hedgehog proteins activate specific genes. The tutorial also covers organ and tissue-specific gene inductions, the mechanism of hedgehog pathway activation, and the resulting intracellular signaling that leads to gene induction. The lesson emphasizes the importance of protein concentration in determining the signaling pathway's outcome.
