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...

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
...or rarely use synthetic pesticides; and sustain or regenerate
the soil quality. Perfecto said the idea that people would go hungry if farming went organic is "ridiculous." "Corporate interest in agriculture and the way agriculture research has been conducted in land grant institutions, with a lot of influ...
Chemotherapy may enhance the effectiveness of brain tumor vaccines
...tudy. "But we found that the process by which they regenerate
makes them strong and hungry -- in a sense, they come back with a vengeance." Cancer vaccines are drugs that enlist the help of the body's immune system to fight cancer cells. "Since the introduction of a vaccine serves to boost immune function, th...

Eye muscles -- those go-getters of the anatomical world
...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. D...

Tissue engineering for craniofacial reconstruction
...transplants. 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

Researchers identify genes that allow brain cancer-causing stem cells to resist treatment
... a tumor is almost completely obliterated, it will regenerate
from the surviving cancer stem cells and be even more resistant to treatment than before. Results of studies on three established glioma cell lines and tumor tissue removed from five patients at Cedars-Sinai appear in the Dec. 2 issue of the journa...
