A major obstacle that scientists faced in new stem cell treatments has been tried to overcome and the obstacle is rejection by the immune system.

It might be possible that immunosuppressive drugs are not used by experts while treating patients with donor stem cells as these drugs are harmful and apart from this, early-stage cells turning into cancerous tumors might also be avoided but the new research has been conducted only in mice.

A range of tissues is what stem cells are capable of taking shape of and these are also known as mother cells. The possibilities are from brain to bone for those that are extracted from embryos that are early stage. Development pathways are limited for adult stem cells that are not developed fully.

It has been figured out by scientists that how adult cells can be reprogrammed into induced pluripotent stem or iPS cells so that embryonic stem cells properties can be given to them.

Medicine can expect a revolution with various kinds of stem cells as for most of the stubborn diseases, treatments will be found.
