Stem Cell Therapy is a modern biotechnology that uses stem cells that come from different parts of one’s body and are of different kinds such as embryonic, adult, and tissue-specific, just to name a few. Stem cells are premature cells that have the ability to divide themselves into various kinds of cells in the body. Moreover, they are able to regenerate and mend damaged tissues from which they came from. There are several views on this biotechnology. Some researchers such as Paul…
