Stem Cells- Types and Therapeutics
Abstract Even before tissue engineering and regenerative medicine took shape, scientists have known about the fact that animals like the star fish were capable of regenerating missing body parts. Although, humans share this ability, humans cannot regenerate a missing finger or toe. Instead, the human body constantly regenerates skin cells, blood cells, and tissues. In the 1950s, experiments were conducted by scientists to identify the source of tissue and cell regeneration in humans. Experiments conducted with the bone marrow revealed the existence of certain powerful cells called stem cells that aided in tissue regeneration. In 1998, James Thompson of the University of Wisconsin-Madison became the first scientist to isolate and use human embryonic stem cells.
