钙离子载体 A23187 促进海鞘 Boltenia villosa 卵中的卵质分离和橙色新月体形成。当鸡蛋暴露于 A23187 梯度时，在对应于离子载体最高浓度的区域中诱导形成橙色新月形。该结果与细胞内钙的局部增加使海鞘胚胎中的细胞质定位极化的假设一致。
Calcium ionophore A23187 promotes ooplasmic segregation and orange crescent formation in eggs of the ascidianBoltenia villosa. When eggs were exposed to a gradient of A23187 the orange crescent was induced to form in the region corresponding to the highest concentration of ionophore. This result is consistent with the hypothesis that a local increase in intracellular calcium polarizes cytoplasmic localization in the ascidian embryo.
