UC Davis stem cell researchers awarded $53 million

UC Davis Health System researchers who are working to speed therapies to patients suffering from critical limb ischemia, osteoporosis and Huntington’s disease received approval today for three separate research grants from the state’s stem cell agency totaling more than $53 million. Each of the research studies that can now begin at UC Davis are specifically designed to lead to U.S. Food and Drug Administration approval of human clinical trials using stem cells and regenerative therapies.

At today’s meeting of the California Institute for Regenerative Medicine (CIRM) in San Francisco, the agency’s 29-member governing board approved five other grant

The Role of Hiwi in Stem Cell Maintenance and Sarcomagenesis

Sarcomas are cancers of connective tissues, such as bone, adipose and cartilage, and are thought to arise from the aberrant development of the mesenchyme. As such, mesenchymal stem cells are thought to be the cell of origin for sarcomas. Genetic or epigenetic lesions at particular points during the differentiation of a mesenchymal stem cell into its terminal mesenchymal cell type are able to give rise to specific subtypes of sarcomas.

Recently, a number of reports have identified elevated expression of the human Piwi homolog–called Hiwi–in a variety of human cancers, including gastric cancer, pancreatic cancer, gliomas and, most relevant for

Enhancing the regenerative capacity of stem cells

tem cell scientists scored what at first appeared an easy win for regenerative medicine when they discovered mesenchymal stem cells several decades ago. These cells, found in bone marrow, can give rise to fat, bone, and muscle tissue, and have been used in hundreds of clinical trials for tissue repair. Unfortunately, the results of these trials have been underwhelming. One problem is that these stem cells don’t stick around in the body long enough to benefit patients.

But Harvard Stem Cell Institute (HSCI) scientists at Boston Children’s Hospital aren’t ready to give up. A research team led by Juan Melero-Martin

Stem Cell Therapy is Reality

The mesenchymal stem cells found in the bone marrow can give rise to bone, fat, and muscle tissue, and have been used in hundreds of clinical trials for tissue repair.

Unfortunately, the results of these trials have been underwhelming, the main problem being that these stem cells do not stick around in the body long enough to benefit the patient.

Researchers have now found that transplanting mesenchymal stem cells along with blood vessel-forming cells naturally found in circulation improves results.

USA/South Korea Stem Cells to Restore Sight and Hearing

Stem cells that could restore sight and hearing have been discovered in an experiment that has been performed successfully in animals. But according to two teams of scientists, it is an important step which will lead to future applications in humans.
A team from the Chonnam National University of South Korea was able to restore hearing in guinea pigs whose hearing was destroyed by chemical substances, using mesenchymal stem cells taken from human bone marrow. Other researchers at SUNY Upstate Medical University of Syracuse in the United States were able to restore sight in frogs using skin stem
