Stem cell: Stem cells are undifferentiated cells that have the potential to develop into many different types of cells in the body. They are distinguished from other cells by their ability to self-renew and differentiate into specialized cell types such as muscle cells, nerve cells, and blood cells. There are two main types of stem cells, embryonic stem cells and adult stem cells. Embryonic stem cells are derived from embryos that are just a few days old, while adult stem cells are found in various tissues throughout the body, such as bone marrow, fat, and blood vessels. Stem cells have the potential to be used for a wide range of medical applications, including regenerative medicine, disease modeling, drug discovery, and transplantation. However, their use is also controversial due to ethical concerns surrounding the use of embryonic stem cells and the potential for misuse in unregulated markets. Research on stem ...
