Yolk inclusions, lipids and polysaccharides found in the chicken embryo blastoderm cells are utilized during the latent period of embryogenesis. The yolk outside the blastoderm is not utilized. A delay in the development of the embryo of first days of incubation is related to a switching over the metabolism from utilizaiton of intracellular nutrient material to assimilation of the extracellular yolk. In the course of morphogenetical movements of the embryo, in the process of gastrulation, took place an increased biosynthesis in the blastoderm cell membranes.
鸡胚胚盘细胞中发现的卵黄包涵体、脂质和多糖在胚胎发生的潜伏期被利用。胚盘外的卵黄未被利用。孵化初期胚胎发育的延迟与新陈代谢从利用细胞内营养物质转变为吸收细胞外卵黄有关。在胚胎形态发生运动过程中，在原肠胚形成过程中，胚盘细胞膜的生物合成增加。
