WebThe hollow blastocyst—which is where embryonic stem cells come from—contains a cluster of 20-30 cells called the inner cell mass. These are the cells that become embryonic stem cells in a lab dish. The process of extracting these cells destroys the embryo. Don’t forget that the embryos were donated from IVF clinics. WebSo, in a blastocyst, there's this little grouping of cells down in here, referred to as the inner cell mass. And this is a really special little bunch of cells that go on to become the embryo. So, these are called stem cells. And what they can do as stem cells is they can specialize into several other cell types.
