Stem cells are cells found in all multi cellular organisms. They are characterized by the ability to renew themselves through mitotic cell division and differentiate into a diverse range of specialized cell types. The two broad types of mammalian stem cells are: embryonic stem cells that are isolated from the inner cell mass of blastocysts, and adult stem cells that are found in adult tissues.
Stem cells can now be grown and transformed into specialized cells with characteristics consistent with cells of various tissues such as muscles or nerves through cell culture.

Isn't it better to find a way to move existing stem cells found in the body to the place you want them? Far less invasive! A chemical pathway can be laid down by signaling existing cells along the route you want them to take. And an electrical charge to the source area of a known amplitude and frequency probably triggers their movement out of the originating area, much like what happens in the embryo.
stem cells carry all the genetic details and are capable of creating the specific organ. The research have practically shown that it can be achieved. Thus stem cell therapy has the potential to cure and replace the useless organs in the body of a patient.
Sorry to inform, that as of now my institute does not offer any collaborative studies in the area of pharmacology. But future is always full of hope till then we can use this platform for furthering research and advanced knowledge.
