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
Scripps Research Institute scientists have offered new hope for parents whose children suffer from the rare genetic disorder ‘cystinosis’ by showing through an experiment on mice that stem cell transplantation can successfully correct the defect (…)
In the study, the researchers used bone marrow stem cell transplantation to address symptoms of cystinosis in a mouse model (…)
In the new study, the researchers found that transplanted bone marrow stem cells carrying the normal lysosomal cystine transporter gene abundantly engrafted into every tissue of the experimental mice (…)
“The results really surprised and encouraged us. Because the defect is present in every cell
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.
