Probably the most well-known and most controversial type of stem cell is derived from a blastocyte, a ball of 150 to 200 cells that forms at the very beginning of embryo development.
This includes totipotent cells (which appear after fusion of gametes) and unfertilized ova into which a cell nucleus has been inserted or whose division has been stimulated by parthenogenesis and the blastocyte.
Embryonic stem cells are pluripotent and derived from blastocyte.
