Calcium-induced dehiscence of cortical granules in Xenopus laevis oocytes
Journal Article

· J. Exp. Zool.; (United States)
Microinjection of 0.1 ..mu..g of Ca/sup + +/ into Xenopus laevis oocytes induces breakdown of the cortical granules. The cortical granules disappeared in both full grown (Stage VI) and small growing (Stage IV) oocytes. Microinjection of Mg/sup + +/, K/sup +/, or Na/sup +/ had no effect on cortical granules in either Stage IV or Stage VI oocytes. Small quantities (0.03 ..mu..g) of Ca/sup + +/ induced dehiscence of the cortical granules only in proximity to the injection site.
