Umbilical Stem Cells May Help Recover Lost Vision for Those With Corneal Disease

CINCINNATI—New research from the University of Cincinnati may help in the recovery of lost vision for patients with corneal scarring.

Winston Whei-Yang Kao, PhD, professor of ophthalmology, along with other researchers in UC’s ophthalmology department found that transplanting human umbilical mesenchymal stem cells into mouse models that lack the protein lumican restored the transparency of cloudy and thin corneas.

Mesenchymal stem cells are “multi-potent” stem cells that can differentiate into a variety of cell types.

These findings are being presented Dec. 8 in San Diego at the 49th Annual Meeting of the American Society of Cell Biology.

Source of invasive bladder cancer found

Philip Beachy, PhD, professor of biochemistry and of developmental biology, said they’ve learned that, at an intermediate stage during cancer progression, a single cancer stem cell and its progeny can quickly and completely replace the entire bladder lining.

With their model in place, the researchers then conducted two main experiments in the mice: In the first experiment, they looked to see what would happen in animals exposed to BBN when the sonic-hedgehog-expressing cells were marked with a distinctive fluorescent color. In the second, they used genetic techniques to selectively kill those same cells in animals prior to exposure with BBN.

Stem Cells Show Promise in Repairing a Child’s Heart

Those suffering from a damaged heart can be treated with their own heart cells. According to a recent research, heart stem cells from children with congenital heart disease can rebuild the damaged heart in the laboratory. The findings apparently have great significance in the health zone.

While conducting the research, cells were achieved from patients ranging in age from a few days after birth to 13 years. These patients were previously subjected to routine congenital cardiac surgery. The number of heart stem cells appears greatest in neonates, that reduce with progression in age. Majority of

Stanford creates first PhD program in stem cell science

Stanford University’s Faculty Senate today approved the creation of what officials believe is the first PhD program devoted solely to stem cell science in the nation and, perhaps, the world. The new doctoral program in stem cell biology and regenerative medicine is also the first interdisciplinary doctoral program created by the School of Medicine in recent years.

School officials say the fact that the university is taking the rare step of creating a new doctoral program acknowledges the growing importance of stem cell research in the realm of biomedical science. The senate’s initial approval

Kidneys grow continuously in adults

Researchers at the Stanford Institute for Stem Cell Biology and Regenerative Medicine and the Sackler School of Medicine in Israel have shown how the kidneys constantly grow and have surprising ability to regenerate themselves, overturning decades of accepted wisdom that such regeneration didn’t happen. It also opens a path toward new ways of repairing and even growing kidneys.

“These are basic findings that have direct implications for kidney disease and kidney regeneration,” says Yuval Rinkevich, PhD, the lead author of the paper and a postdoctoral scholar at the institute.

The findings were published online May 15 in Cell Reports.
