Resumen de Parkinson's stem cell breakthrough
Jun Takahashi at Kyoto University, Japan, and colleagues wondered whether they could treat monkeys with a disease like Parkinson's using induced pluripotent stem cells, which are made by coaxing blood or skin cells into becoming stem cells. The team generated stem cells from three people with Parkinson's and four without the disease. They then transformed these into dopamine-producing brain cells. All the monkeys who received injections of these cells showed a 40% to 55% improvement in their movements, matching results from previous experiments with embryonic stem cells. Monkeys who had a control injection minus the cells didn't improve.
