...ports horses to their former glory. "Our aim is to regenerate the tendon structure that does not repair spontaneously," says Galli. Once scar tissue is formed, it hinders the animal’s recovery. "If you intervene, with cell transplants, within one week, you can repair the lesion," Galli notes. Like horses, hum...Tissue engineering for craniofacial reconstruction

Tissue engineers attempt to repair or regenerate damaged tissue by using engineered tissue substitutes that can sustain functionality during regeneration and eventually integrate into the host tissue. The traditional tissue-engineering paradigm combines isolated cells with appropriate bioactive age...Scientists re-grow dental enamel from cultured cells
...the hardest tissue produced by the body. It cannot regenerate itself, because it is formed by a layer of cells that is lost by the time the tooth appears in the mouth. The enamel spends the remainder of its lifetime vulnerable to wear, damage, and decay.

...bilizing the structure of adult stem cells as they regenerate and divide into daughter cells. "Normal basal epithelial tissue produces nestin, but basal epithelial tumors produce a tremendous amount of nestin, which likely represents an abnormal expansion of the basal epithelia." DiRenzo said. "If it is in...Liver regeneration may be simpler than previously thought
...iver is one of the few organs in the body that can regenerate from as little as 25 percent of its tissue," says Seth Karp, assistant professor of surgery at Harvard Medical School, Boston, and main author of the study.

"Our findings provide additional evidence that cAMP plays an important role in axon growth and suggest that these receptors are likely to play a major role in regulating cAMP production in nerve cells," says Saeki, an associate pro...The sturdier sex? -- Study by Pittsburgh scientists finds female stem cells work better
