...fered heart attacks, and see if the new tissue can heal the damage. This work is being conducted by Francesco Migneco, M.D., a research fellow with the Artificial Heart Laboratory.

Controlling not only what types of cells differentiate from stem cells, but also gaining spatial control of stem cell differentiation, are important capabilities if researchers are to engineer replacement tissues that...Pittsburgh-based team engineers muscle, bone cell differentiation with aid of ink-jet printer

... novel insight into the brain's natural ability to heal might ultimately have clinical implications for the treatment of brain damage, according to the researchers.

... DNA employs some chemical reactions of its own to heal itself. But when DNA sustains too much damage, it can't replicate properly. Badly damaged cells simply die -- the effect that gives sunburn its sting. Scientists also believe that chronic damage creates mutations that lead to diseases such as skin ca...New study finds genetic link between women and heart disease
... disease. Inflammation is necessary to repair and heal nicks to the lining of blood vessels, which occur daily. The variant form of the LTC4S gene however, leads to an excessive inflammatory response at the site of blood vessel injury. As a result, people who inherit this gene variant dont repair damag...Carnegie Mellon researcher proposes development of artificial cells to fight disease

Because the cell is an amazingly efficient system already, LeDuc and his team of researchers plan to use its microscopic package of tightly organized parts to improve medical treatment in diseases that exist in the body.

...o natural, does that mean we should let our bodies heal themselves and not try and interfere with modern medicine? A: Absolutely not.
