(Ivanhoe Newswire) -- As debilitating as disease can be, finding paths that could possibly lead to a cure is quite rewarding. Researchers at Harvard Medical School and the Harvard School of Dental Medicine have found that by mimicking a rare genetic disorder in a dish, they can rewind the internal clock of a mature cell and drive it back into an adult stem-cell stage. This new "stem cell" can then branch out into a variety of differentiated cell types, both in culture and in animal models....

Researchers in the United States have developed a medical model for regenerating bladders using stem cells harvested from a patient's own bone marrow. The research, published in Stem Cells, is especially relevant for paediatric patients suffering from abnormally developed bladders, but also represents another step towards new organ replacement therapies. The research, led by Drs Arun Sharma and Earl Cheng from the Feinberg School of Medicine at Northwestern University, focused on bone marrow...

(Ivanhoe Newswire) "“ Umbilical cord stem cells may be useful in the treatment of rheumatoid arthritis (RA), according to in vitro experiments done on animals. The researchers show that mesenchymal stem cells (MSCs) taken from the umbilical cord blood can suppress inflammation and weaken collagen-induced arthritis. "Very little is known about umbilical cord MSCs, and there has been no previous report about their use in the treatment of RA. MSCs can exert profound immunosuppression,...

Bioengineers from the University of California, San Diego have achieved the "Triple Crown" of stem cell culture "“ they created an artificial environment for stem cells that simultaneously provides the chemical, mechanical and electrical cues necessary for stem cell growth and differentiation. Building better microenvironments for nurturing stem cells is critical for realizing the promises of stem-cell-based regenerative medicine, including cartilage for joint repair, cardiac cells for...

Gadonanotubes (GNTs) developed at Rice University are beginning to show positive results in a study funded by a federal stimulus grant through the National Institutes of Health (NIH) last year. The study has determined GNTs are effective in helping doctors track stems cells through the body by making them 40 times better than standard contrast agents used in magnetic resonance imaging. Contrast agents help doctors spot signs of disease or damage in MR images. Researchers at Rice and the Texas...

Many scientists aspire to take control over the stem cell differentiation process, so that we can grow organs and implants perfectly matched to each patient in the future. Now research in the Journal of Tissue Engineering, published by SAGE-Hindawi, explains how engineering the topography on which stem cells grow, and the mechanical forces working on them, can be as powerful an agent for change as their chemical environment. Stem cells respond to the stiffness, chemistry and topography of the...

Biomedical researchers at the University at Buffalo have engineered adult stem cells that scientists can grow continuously in culture, a discovery that could speed development of cost-effective treatments for diseases including heart disease, diabetes, immune disorders and neurodegenerative diseases. UB scientists created the new cell lines "“ named "MSC Universal" "“ by genetically altering mesenchymal stem cells, which are found in bone marrow and can differentiate into cell...

Aging disrupts the balance between bone formation and bone destruction, resulting in osteoporosis, which is characterized by reduced bone mass and increased risk of fracture. Recent data have suggested that this imbalance is a result of a decrease in formation of bone forming osteoblast cells from mesenchymal cells upon aging. Instead, these cells form more fat cells. Insight into this age-related switch in cell type generation has now been provided by a team of researchers, led by Hiroshi...

For most people, wisdom teeth are not much more than an annoyance that eventually needs to be removed. However, a new study appearing in the September 17 Journal of Biological Chemistry shows that wisdom teeth contain a valuable reservoir of tissue for the creation of stem cells; thus, everyone might be carrying around his or her own personal stem-cell repository should he or she ever need some. Groundbreaking research back in 2006 revealed that inducing the activity of four genes in adult...
