WebJun 15, 2013 · Another common consequence of transplanting nuclei from differentiated cells is the formation of partially cleaved embryos, which either die prior to gastrulation or form abnormal gastrulae. Typically, these have normal-looking blastomeres in about half of the embryo while about half are undivided. WebNevertheless, the formation of the epithelium on the surface of the embryo, after the nuclei have migrated to the exterior, can be compared to the formation of the blastula. The layer of cells thus formed on the surface of the embryo is the blastoderm. Instead of surrounding a cavity, the blastoderm envelops the mass of un-cleaved yolk.
