Loading ...Stem cell research is done on stem cells to study various diseases. Stem cells are undifferentiated cells which can change into any specialized cell in body. Stem cells are also used these days for organ transplants.
Stem cells for research are taken from spare embroys that remain after in vitro fertilization (IVF). In IVF many ova are fused with sperms to form embryos.. and some of them are implanted in the uterus.
The spare embryos are used for stem cell research. They can also be used for organ transplantation.
