MSH: Cells derived from the BLASTOCYST INNER CELL MASS which forms before implantation in the uterine wall. They retain the ability to divide, proliferate and provide progenitor cells that can differentiate into specialized cells.,CSP: undifferentiated cell in an embryo which can undergo division and give rise to one or several cell types; cell line is derived from early blastocytes; for human embryonic stem cells, use HUMAN EMBRYONIC STEM CELL LINE.,NCI: Embryonic stem (ES) cells are cells derived from the inner cell mass of the early embryo that can be propagated indefinitely in the primitive undifferentiated state while remaining pluripotent.
