In mammals, there are four (4) main types and sources of stem cells being Embryonic, Foetal, Infant and Adult:
(i) Embryonic Stem Cells are isolated from the inner mass of blastocyst being the early embyogenesis of mammals; and
(ii) Foetal Stem Cells are isolated from the umbilical cord, when the foetus is born and not aborted; and
(iii) Infant Stem Cells are isolated in high numbers from the blood from infants under the age of three (3); and
(iv) Adult Stem Cells are isolated mainly from bone marrow and to a lesser extend from the blood.
