WebMay 7, 2024 · A stem cell, found in embryos (embryonic stem cell) and adults (somatic stem cell), is an immature, non-specialized cell that can differentiate into one or more specific functioning or regenerating cell types. This makes them of use in the treatment of degenerating diseases. Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. These daughter cells become either new stem cells or specialized cells … See more Researchers hope stem cell studies can help to: 1.
