Although we touch upon asymmetric cell divisions in the early C. We focus on asymmetric cell divisions that occur during the development of the Caenorhabditis elegans and Drosophila nervous systems. Recent studies have indicated that a combination of intrinsic and extrinsic mechanisms specify distinct daughterĬell fates during asymmetric cell divisions. Interaction between a progenitor cell and its environment canĪlso influence cell polarity by directing spindle orientation and the asymmetric distribution of developmental potential toĭaughter cells. Interactions between daughter cells or between a daughterĬell and other nearby cells could specify daughter cell fate. Positional information and opportunity for cell–cell interactions. In metazoans, a dividing’s cell’s social contex provides a wealth of Extrinsic mechanisms involve cell–cell communication.
