The human body contains unspecialized stem cells. They have the capacity to regenerate and differentiate into every type of cell in an organism. Both embryo and adult tissues contain stem cells. They have different stages of specialisation. Each stage lowers the potential for development, producing unipotent stem cells instead of pluripotent ones, which can differentiate into a greater variety of cell types.

• Adult stem cells
• Adult cells altered to have properties of embryonic stem cells
• Perinatal stem cells
