Stem cells are the new focal point of the rich and famous. Hollywood A-listers are reported to be spending tens of thousands of dollars each year on expensive therapies offered by private longevity clinics that promise to regenerate the ageing body.Stem cells have long been regarded as one of the great hopes of regenerative medicine.
It is not hard to find evidence of the potential dangers. Just last year, reports emerged of patients in the US losing their sight after receiving a stem cell treatment for a degenerative eye condition at a private clinic in Florida. Some clinics claim to offer injectable stem cell therapies that boost collagen and give the face a more youthful appearance. But scientists say there is little published evidence that this is either safe or effective.
“You’re looking to get rid of the disease and then replace the blood system with some fresh stem cells,” he says. “It’s tried and tested and proven to work.” “These cells travel around the body and when they discover a place that needs repair, they’ll change into the cells that you want for repair, so they might become cartilage cells or liver cells,” he says.
Various clinical trials are now taking place in the UK in which this same approach is being tested as a possible treatment for. Other trials are investigating whether new drug therapies can help combat conditions such as age-related muscle wasting by stimulating muscle stem cells and making them more active.
