This could have important implications for those suffering from Parkinson's and Alzheimer's. If the process can actually be perfected to the extent that production costs are reduced and the quality of the eventual product is improved, then this would be a legitimate research goal. The simplicity of the technique, though still inefficient, makes this plausible. But there are still questions that need to be answered. One critical question concerns the lifespan of Dolly.
All cells have a built in senescence or death after so many cell divisions.
Dolly began with a cell from a ewe that was already six years old. A normal lifespan for a ewe is around 11 years. Actually most cell divisions are used up during embryological development. Dolly's cells may peter out even earlier. My guess though is that since Dolly's genes were reprogrammed from mammary cell functions to embryological functions, that the senescence clock was also reset back to the beginning.
