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 struLATER 发表于 2025-3-24 03:20:39
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 foAirtight 发表于 2025-3-24 07:33:37

, and , Studies on the Differentiation of the Neural Crest in the Avian Model, the neural tube is closing, the neural crest cells leave their original position and undergo extensive migrations through the developing embryo, settle to various homing sites where they give rise to a large diversity of different cell types. Therefore, the ontogeny of the neural crest constitutesMIRE 发表于 2025-3-24 15:07:16

Marilyn Monk. Auch die wirt schaftliche Bedeutung sollte dabei berücksichtigt werden, sonst kommt ein Teil der investierten Material- und Lohnkosten nicht zur Auswirkung. Nicht selten wird der Gebrauchswert falsch ausgelegt und mit anderen Begriffen verwechselt. H. SOMMER definierte ihn sehr klar verständl
