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.

For organ transplantation, stem cells from persons own body can also be used. They are less susceptible to rejection by the patient’s body. However, if stem cells from a donor have to be used for organ transplants, embryonic stem cells are a better option.

There are several ethical issues involved around stem cell research. People against it say that we are killing the embryos for our purpose. However, the fact is that if we don’t use them, they are gonna die anyways!!!! So why not take permission from the parents and make gud use of their embryos!!!!

    This is a good piece of information! Where I can find more information on how stem cells are preserved?

    Hi Anurag,
    Usually stem cells are preserved by cryo preservation. That is they are kept at very low temperatures.
    For more information on stem cells you can visit NIH’s site. It is US govt site. Here is the link
