Structure and Function of Cadherins,ins mediate homophilic interactions and are thought to be responsible for the selective cell-cell adhesion or cell sorting that is necessary to position different cell types during development (Takeichi, 1988). Cadherins also play a fundamental role in maintaining the integrity of multicellular stru

An Elevation of Internal Calcium Occurring Via L-Type Channels Mediates Neural Induction in the Ampthe ectoderm (target tissue). The mechanism of neural induction has been the subject of many investigations more than 60 years (Saxén, 1989; Duprat et al. 1990; Westenbroeck et al. 1990). Although the natural inducer still remains unidentified, numerous, apparently unrelated, substances have been fo
