Researchers have already shown that adult bone marrow cells guided to become heart-like cells can repair heart tissue in people, and more research is ongoing. De la Torre P, et al. Embryonic stem cells can also grow irregularly or specialize in different cell types spontaneously. In some instances, the organism can continue to live with the aid of medical treatment, for example, replacement of insulin or by organ transplantations. Dermabrasion may be used to minimize small scars, minor skin surface irregularities, surgical scars, and acne scars.
