Mouse severely disabled by a condition similar to multiple sclerosis (MS) could walk less than two weeks following treatment with human stem cells.
When scientists transplanted human stem cells into MS mice, they expected no benefit from the treatment. They thought the cells would be rejected, much like rejection of an organ transplant.
Instead, the experiment yielded spectacular results.
Within a short period of time, 10 to 14 days, the mice could walk and run. Six months later, they showed no signs of slowing down.
A team led by Peter Schultz, Scripps Family Chair Professor and member of the Skaggs Institute for Chemical Biology at The Scripps Research Institute, has been awarded a $4.3 million grant from the California Institute for Regenerative Medicine (CIRM) to research stem-cell-based therapies to treat multiple sclerosis.
Because stem cells can change or differentiate into many different cell types (such as nerve cells, muscle cells, and skin cells), they hold the life-changing medical potential to provide a source of cells to replace those permanently lost by a patient.
The Scripps Research project focuses on restoring the myelin sheath—a protective covering that

UC Irvine scientists have shown for the first time that neural stem cells can rescue memory in mice with advanced Alzheimer’s disease, raising hopes of a potential treatment for the leading cause of elderly dementia that afflicts 5.3 million people in the U.S.
Mice genetically engineered to have Alzheimer’s performed markedly better on memory tests a month after mouse neural stem cells were injected into their brains. The stem cells secreted a protein that created more neural connections, improving
An international team of scientists led by researchers at The Scripps Research Institute has developed a straightforward technique to determine the ethnic origin of stem cells.
The team’s analysis of a variety of human embryonic stem cell lines currently in use in research laboratories around the world found that these cells originated largely from Caucasian and East Asian populations, with little representation from populations originating in Africa. In response to these results, the scientists used skin cells from an individual of West African Yoruba heritage to create a new stem cell line, the first to carry the genetic profile of

Sheng Ding, the leader of a group of researchers at the Scripps Research Institute of the La Jolla University in California, spoke about using chemistry-related techniques to obtain pluripotent stem cells from a miniscule section of skin at Milan University in a conference on stem cells.
Experts were able to cause some skin cells in mice to regress to their embryonic state by injecting four proteins into an adult mouse without performing any sort of DNA manipulation. A technique that, according to their idea, could be safer than techniques based on genetic manipulation. The
