But a major obstacle has been delivering a reliable blood supply to the growing tissue.\u003cbr/\u003eNow, scientists at Stamford university claim they have a solution to the problem.\u003cbr/\u003e[Notes:Dr. Geoffrey Gurtner, Stanford University, associate professor of surgery]\u003cbr/\u003eThe new technique utilizes a lump of flesh as what can be described as a \"bio-scaffold,\" or a seeding bed for the stem cells.\u003cbr/\u003e[Notes:Dr. Geoffrey Gurtner, associate professor of surgery, Stanford University]\u003cbr/\u003eThe tissue is kept alive by pumping a blood-like liquid through the existing mass of vessels. The tissue would die quickly without this life-support system,  which keeps it healthy long enough to embed the stem cells. \u003cbr/\u003e[Notes:Dr. Jason Glotzbach]\u003cbr/\u003eThe whole mass of tissue is finally reinserted into the animal, gradually transforming into new types of cells.  And because the animal's own tissue is used, it is less likely to be rejected by the body than synthetic tissue. \u003cbr/\u003eSo far all the experiments have been restricted to rats so there is no guarantee that this technique will work in humans. But the research has overcome a major stumbling block to moving stem cell research forward.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container flex
