In Utero Stem Cell Transplants, Enzyme Replacement May Offer New Treatments for Deadly Metabolic Disorders

Administering stem cell or enzyme therapy in utero may be a path to alleviating some congenital diseases that often result in losing a pregnancy, according to a new study in mice by UC San Francisco researchers, who showed that stem cells can enter the fetal brain during prenatal development and make up for cells that fail to make an essential protein. Each year, about 24,000 women […]

DNA Misfolding in White Blood Cells Increases Risk for Type 1 Diabetes

It’s known that genetics, or an inherited genome, is a major determinant of one’s risk for autoimmune diseases, like Type 1 diabetes. In human cells, a person’s genome—about six feet of DNA—is compressed into the micrometer space of the nucleus via a three-dimensional folding process. Specialized proteins decode the genetic […]

Establishment of a cat genome analysis platform

Cats share around 250 types of genetic diseases with humans, and they are seen as a next-generation animal model for diseases. During his days as a veterinarian, Project Professor Watanabe saw many animals succumb to diseases, including genetic diseases which were incurable. He presses forward with his research on cat […]

Diabetes in mice cured rapidly using human stem cell strategy

Researchers have converted human stem cells into insulin-producing cells and demonstrated in mice infused with such cells that blood sugar levels can be controlled and diabetes functionally cured for nine months. The findings, from researchers at Washington University School of Medicine in St. Louis, are published online in the journal […]
