Notch-Blocking Drugs Kill Brain Cancer Stem Cells, Yet Multiple Therapies May Be Needed

Friday, February 26th, 2010
Working with mice, Johns Hopkins scientists who tested drugs intended to halt growth of brain cancer stem cells a small population of cells within tumors that perpetuate cancer growth conclude that blocking these cells may be somewhat effective, but more than one targeted drug attack may be needed to get the job done...

Stem Cell Therapy Removes Cell Receptor That Attracts HIV

Friday, February 26th, 2010
UCLA AIDS Institute researchers successfully removed CCR5 a cell receptor to which HIV-1 binds for infection but which the human body does not need from human cells. Individuals who naturally lack the CCR5 receptor have been found to be essentially resistant to HIV...

Stem Cells Restore Sight In Mouse Model Of Retinitis Pigmentosa

Friday, February 26th, 2010
An international research team led by Columbia University Medical Center successfully used mouse embryonic stem cells to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa. This strategy could potentially become a new treatment for retinitis pigmentosa, a leading cause of blindness that affects approximately one in 3,000 to 4,000 people, or 1...
