Embryonic stem cell
Type of pluripotent blastocystic stem cell
Embryonic stem cells (ESCs) are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage 4โ5 days post fertilization, at which time they consist of 50โ150 cells. Isolating the inner cell mass (embryoblast) using immunosurgery results in destruction...
