A REVOLUTIONARY jab made from stem cells found in tummy fat could soon stop osteoarthritis in its tracks. The breakthrough provides hope for the eight million people in the UK who suffer from the incurable condition and could potentially save thousands from needing joint replacement surgery. Dutch and French researchers found injecting stem cells harvested from a patients own waistline protects joints against crippling damage. It appears to be the closest experts have come to halting the disease using stem cells. A single dose of stem cells extracted from adipose tissue fat which accumulates around the stomach more than halved damage to knee joints in mice. The findings, revealed at the American College of Rheumatology in Chicago, could mark a turning point in the search for a treatment. Osteoarthritis is the most common type of arthritis in the UK. It can inflame and damage any joints, but occurs mostly in the knees and hips. Some joints become so severely worn down they require surgery. MO
