Quizplus · Accepted Answer

Umbilical cord blood contains stem cells that can be used to treat a variety of diseases, including Parkinson's disease. These stem cells have the potential to develop into various types of cells in the body and can be used to replace damaged or diseased cells. Human embryos are another potential source of stem cells, but the use of embryonic stem cells is controversial and subject to ethical debate.
