what's new about origin cells ?

Question

as i heard , scientists had found that cells that make bodies organs can make new organs in body when we put them in our body , is it true ??

Answer 1

Like Mr. Cannabis above, I think what you mean by 'origin cells' are actually usually called 'stem cells'.

Stem cells can come from two sources: from the embryo or from adult tissues.

Since we each developed from a single cell, the fertilized egg, it is obvious that if cells can be taken from early embryos, they will probably have the potential to become any organ. And this has been demonstrated experimentally many times.

However, it is not clear how we can control the process to specifically replace a damaged cell type, tissue or organ. So, although there is a lot of promise, no doctor is able to replace a damaged kidney or liver, for example, with embryonic stem cells.

In the case of adult stem cells, there is even less known. There seem to be cells capable of repairing organs in adults, but it is not clear how effective they will be or whether we can even collect enough of them to be very useful.

These are complicated technical issues with lots of ethical considerations to take into account, but there is certainly a lot of information available if you want to learn more.

Just remember: although these cells show great promise for curing diseases and healing the sick, many of these cures may still be years away in the future.

Answer 2

Partly true, but not every kind of cell, only the ones that have not developed into particular tissue yet, so called stem cells, for example from our bone marrow or from blood of the umbilical cord.
