However, each time the cells d...e telomeres get short enough, maybe the cells cant regenerate any more and maybe thats why you start to see this change, said Dr. Spechler. Perhaps the esophagus ...Stanford researchers find culprit in aging muscles that heal poorly
...h showing that the ability of muscle stem cells to regenerate tissue depends on the age of the cells' environment (including the age of the blood supplying the tissue), not the age of the stem cell. Although Rando's research focused on the repair of acute trauma to muscles, he suspects that the same sort of p...W.M.

Building on previous research ...between the age of stem cells and their ability to regenerate themselves, Dr. Wagers hopes to discover a method to slow down or reverse the natural process of agi...UD scientists invent novel hydrogels for repairing, regenerating human tissue
...azing organ, Schneider said. It has the ability to regenerate itself quite easily. If almost 70 percent of it is lost to disease and removed, that remaining 30 percent can grow back, affording a functional liver. We want to use the hydrogels to deliver hepatocytes to the liver, he noted. These could be used to ...Organic farming can feed the world, U-M study shows

...s of the limbs. There is evidence that eye muscles regenerate much faster than skeletal muscle of the limbs. This may be a key to why the eyes have a greater ability to withstand the onslaught of muscular dystrophy. Another very important aim of Dr. McLoons research is to find new drugs to treat strabismus.

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. For this reason, it is exciting to consider the prospect ...Cells passed from mother to child may be first step in developing new treatments for type 1 diabetes
...m. "We think the maternal cells may be helping to regenerate damaged tissue in the pancreas," Nelson said. She said investigators are excited about new possible approaches to treat Type 1 diabetes raised by their findings. For example, if maternal microchimerism results in cells that make insulin, a mother's s...Common blood pressure drug treats muscular dystrophy in mice
