Making new muscle: Researchers in Rome produce a mouse that can regenerate its tissues
...njured. This made us think it might play a role in regenerating damaged tissues." They created a strain of mouse whose muscle cells continue to produce mIGF-1 throughout its lifetime. In order to study the activity of stem cells at the injury site and to trace those cells back to their source, the authors generat...Chemical that turns mouse stem cells into heart muscles discovered by Scripps researchers
...urons in the brain are lost, may be ameliorated by regenerating neurons. And Type I diabetes -- in which beta cells are lost -- might be treated by generating new beta cells. Likewise, a damaged heart, which is composed mainly of cardiac muscle cells that the body may be unable to replace once lost, could p...UCSF finding advances insight into adult stem cells in human brain
...otentially could be used to develop strategies for regenerating damaged brain tissue - and that could offer new insight into the most common type of brain tumor. The study, conducted by investigators in the UCSF Department of Neurological Surgery, is the cover story in the Feb. 19 issue of Nature . The rese...Regeneration of injured muscle from adult stem cells
...ured tissue. They show that stem cells taken from regenerating muscle in mice lacking the Pax7 gene could not become muscle cells, and that by putting Pax7 back into stem cells taken from uninjured muscle, they can generate a population of cells that readily differentiate into muscle cells. When stem cells engin...Embryonic stem cell - based tissue engineering may help repair damaged heart muscle
NEW YORK--Embryonic stem cells may hold the key to regenerating damaged heart muscle, when transplanted within a 3-dimensional scaffold into the infracted heart, according to a new study coming out in June in the Journal of Heart and Lung Transplantation. In the study, embryonic stem cells were more successful in...Some plants may compensate for herbivore damage by stimulating nutrient release in the soil

By regenerating diseased myocardium and promoting cardiac repair, embryonic stem cells provide a unique therapeutic modality that has the potential to reduce the morbidity and mortality of this prevalent heart disease."

...roup known as echinoderms, crinoids are capable of regenerating lost body parts. Because modern day crinoids usually lose---and regenerate---their arms as a result of attacks by fish, Baumiller and Gahn reasoned that arm regeneration in fossil crinoids would be a good indicator of predator-prey interactions in th...
