Master gene controls healing of skin in fruit flies and mammals

...ies a master gene called grainyhead that activates wound repair genes in the cells surrounding an injury in the cuticle of a fly embryo. These wound repair genes then regenerate the injured patch of cuticle. In a separate study published in the sam...

Heart repair gets new muscle

... body deal with injury better than others. A flesh wound or muscle tear might hurt, but, assuming you are otherwise healthy, both will heal. The prognosis for a heart attack, on the other hand, is not so clear-cut. It has long been thought that cardiac cells (cardiomyocytes) lack the capacity for self-ren...

...nea is a foreign body, it doesn't "heal" the way a wound would and become a part of the body. There could be complications over time, such as thinning of the tissue surrounding the implant or the development of glaucoma due to preexisting imperfections in the draining mechanics of the eye, according to Afs...

U-M scientist to talk about tissue engineering at AAAS

...e the hip. That approach has problems both for the wound at the donor site and for the site where it is implanted. In addition to discussing the sometimes-messy real world applications of tissue engineering, Krebsbach plans to talk at AAAS about the potential for combining seemingly unrelated therapies to...
