Calcium Mobilization Systems During Neurogenesis.

Neuroepithelial cells have Ca(2+) mobilization systems that are activated by acetylcholine via muscarinic receptors and by extracellular ATP via P(2U) purinoceptors. The Ca(2+) mobilization occurs during neurogenesis and diminishes in parallel with the declining of mitotic activities of the neuroepithelial cells. Capacitative Ca(2+) influx also occurs with the Ca(2+) mobilization.
