Explain how human embryonic stem cells, adult stem cells and skin cells taken from the same person would be the same and how they would be different? Explain what causes the differences you describe.

Embryonic stem cells - Totipotent - can develop into any (all) type of tissue. Adult stem cells - Pleuripotent - can develop into many (not all) types of tissue. Skin cells - Non potent differentiated cells - can develop as skin tissue only. It is due to level of differentiation. Embryonic stem cells are undifferentiated. Adult stem cells are slightly differentiated. Skin cells are fully differentiated cells.
