No other cell offer perform the same functions as stem cells. new(prenominal) cells in the body have limited functions and they do not replicate.
Stem cells are discordent form other cells because they have a special signal that other cells do not. These signals are produced by the cell?s genes, which are located on the cells DNA. The genes act as a messenger and send specific instructions about the cells function. Scientists are studying how these genes differ on each stem cell an! d if the signal can be altered. By studying this, the scientists are learning how to learn the cells signals. If scientists can learn how to control the stem cells, they may be...
