Scientists grow blood vessels for human surgery
Scientists can grow blood vessels in a lab for use in coronary bypass or dialysis, a promising alternative to harvesting from the patient, said a study published on Wednesday.
The process involves taking smooth muscle cells from a human cadaver and grafting them onto tubes made of the material used in making dissolvable stitches, called polyglycolic acid.
Within eight to 10 weeks, the tubes degrade and a "fully formed vascular graft" remains, said the research by scientists from Duke University, East Carolina University and Yale University.
