摘 要：The region between the preexisting and nascentmembranes of a cleaving Rana egg is a dense protrusionregion of nearly 40μm wide at 180°***,thisregion differentiate,into an upper part,a strip withlong, branched and randomly distributed protrusionswhich are derived largely from the preexistingmembrane,and a lower part,a band with *** 4-and 8-cel1 stages,the strip is almost vanishedand microvilli in the band is *** nascentmembrane is smooth at the 180°stage,then a rough areaappears below the smooth region and quickly *** germ agglutinin which can bind to preexistingmembrane interrupts the development of the regionbetween the preexisting and nascent ***,Brij,having the property to increase the areaof nascent membrane,does not interrupt the developmentof the region between the preexisting and nascentmembranes.
