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.

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.
