In most cases, yes. The hollow blastocystâwhich is where embryonic stem cells come fromâcontains 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. Donât forget that the embryos were donated from IVF clinics.
