uuddlrlrab sends along this quote from a report in Nature: "The Stanford researchers used liposuction to extract a couple liters of fat from the bellies of four overweight individuals aged 40 to 65. They then treated the tissue to remove all the gooey, globular fat, leaving behind a collection of fat tissue stem cells. Unlike standard techniques, which require about a month to culture skin biopsies to populations large enough for the reprogramming process, the fat tissue was ready to go after two days of pretreatment. What's more, the cellular reprogramming took only two more weeks and was 20-times more efficient than when converting fibroblasts using the same technique. 'We basically shave off six to eight weeks compared to what the other guys are doing with fibroblasts,' says [Stanford's Joseph Wu], who is now working to find safer ways to reprogram fat without using viruses."
