Understanding the processes that lead to tissue damage in MS is crucial to our focus on reversing this damage to regain function through nervous system and myelin repair. information submitted for this request. When a scar develops, collagen fibers repair damaged skin and close any open areas. The fibrotic scar tissue shores up the damage but it cannot replace the function of the lost hepatic tissue. Therapeutic cloning, also called somatic cell nuclear transfer, is a technique to create versatile stem cells independent of fertilized eggs. One type of collagen (made from purified cow collagen) is injected beneath the skin.

This is a newer technique. 7272 Greenville Ave. Sometimes, the injections help to decrease the size of the scar and soften the scar tissue. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body.
