The Independent takes a look at TriStem and their claimed retrodifferentiation technology. "A London-based biotech company says it can take an adult human cell from a patient and use it to create a stem cell. If ongoing medical trials being conducted in India to substantiate these claims prove successful, the whole issue will be turned on its head." We'd all like this to work, but it's best to wait for confirmation from the wider scientific community before getting too excited. The ability to create stem cells on demand from a patient's own tissue would certainly be a large step forward for regenerative medicine - although it still leaves the issue of how to deal with age-related damage to DNA.
