Embryonic stem cells are cultured cells obtained from the Undifferentiated inner mass cells of an early stage human Embryo (sometimes called a Blastocyst, which is an Embryo that is between 50 to 150 cells). Embryonic stem cell research is "thought to have much greater developmental potential than adult Stem Cells," according to the National Institutes of Health.
