Elusive pancreatic progenitor cells found in mice
01-25-2008 · EurekAlert!Researchers in Belgium have significantly advanced the discovery of a pancreatic progenitor cell with the capacity to generate new insulin-producing beta cells. If the finding made in mice holds for humans, the newfound progenitor cells may represent "an obvious target for therapeutic regeneration of beta cells in diabetes," the researchers report in the Jan. 25 issue of the research journal Cell, a publication of Cell Press.

- Mass. General researchers identify master cardiac stem cell
11-22-2006 · EurekAlert!
Researchers from the Massachusetts General Hospital Cardiovascular Research Center have discovered what appears to be a master cardiac stem cell, capable of differentiating into the three major cell types of the mammalian heart. In a report to appear in the journal Cell, receiving early online release, they describe identifying these progenitor cells in mice, cloning them from embryonic stem cells, and showing that cloned cells can differentiate into cardiac muscle, smooth muscle or endothelial cells.

- Immunosuppressive drugs are a double-edged sword to type 1 diabetics
09-04-2007 · EurekAlert!
Type 1 diabetes occurs when immune cells destroy pancreatic insulin producing beta-cells. It was hoped that islet transplantation would provide a cure for the disease, however, transplant success is short-lived and accompanied by significant side effects. New data indicate that the immunosuppressive drugs used to prevent islet transplant rejection suppress beta-cell regeneration in diabetic mice, raising the possibility that identifying immunosuppressive drugs that do not inhibit beta-cell regeneration might lead to successful regenerative islet transplantation.

Just as many scientists had given up the search, researchers have discovered that the pancreas does indeed harbor stem cells with the capacity to generate new insulin-producing beta cells.

- Loss of stem cells correlates with premature aging in animal study
06-06-2007 · EurekAlert!
Researchers at the Abramson Family Cancer Research Institute of the University of Pennsylvania have found that deleting a gene important in embryo development leads to premature aging and loss of stem cell reservoirs in adult mice. This gene, ATR, is essential for the body's response to damaged DNA, and mutations in proteins in the DNA damage response underlie certain types of cancer and other disorders in humans.

- Stem cells show promise for treating Huntington's disease
09-25-2007 · EurekAlert!
Paying close attention to how a canary learns a new song has helped scientists open a new avenue of research against Huntington's disease -- a fatal disorder for which there is currently no cure or even a treatment to slow the disease. Scientists used gene therapy to guide the development of endogenous stem cells in the brains of mice affected by a form of Huntington’s, generating new medium spiny neurons -- the cell lost in Huntington's disease.

12-07-2007 · Massachusetts Institute of Technology (MIT)
MIT researchers have successfully treated mice with sickle-cell anemia in a process that begins by directly reprogramming the mice's own cells to an embryonic-stem-cell-like state, without the use of eggs.

- Team of scientists develops non-invasive method to track nerve-cell development in live human brain
11-08-2007 · EurekAlert!
A team of scientists including researchers at Cold Spring Harbor Laboratory have identified and validated the first biomarker that permits neural stem and progenitor cells to be tracked, non-invasively, in the brains of living human subjects. This important advance could lead to significantly better diagnosis and monitoring of brain tumors and a range of serious neurological and psychiatric disorders.

- Replacing the cells lost in Parkinson disease
12-03-2007 · EurekAlert!
Parkinson disease is caused by the progressive degeneration of dopamine brain cells. Replacing these cells is considered a promising therapeutic strategy. Although DA cell-replacement therapy by transplantation of human fetal mesencephalic tissue has shown promise, limited tissue availability means other sources of these cells are needed. A recent study has described one new source for DA cells that provided marked benefit when transplanted into mice with a PD-like disease.

- Pittsburgh-based team engineers muscle, bone cell differentiation with aid of ink-jet printer
12-10-2006 · EurekAlert!
A team of researchers from Carnegie Mellon University and the University of Pittsburgh has created and used an innovative ink-jet system to print "bio-ink" patterns that direct muscle-derived stem cells from adult mice to differentiate into both muscle cells and bone cells. The results, which could revolutionize the design of replacement body tissues, will be presented Sunday, Dec. 10 at the 46th annual meeting of the American Society for Cell Biology in San Diego.
