stem cell clinic - An Overview
The zygote, which can be the cell resulting from the fertilization of the oocyte by a spermatozoon, is totipotent. Various successive cell divisions make the morula, with 32–sixty four totipotent cells. After that phase, it develops in to the blastocyst, which is made up of a hollow ball of cells. Peripheral cells (the trophoblast) from the blast
