Spinning Muscle Fibers

Nov-16-17 A new spraying method of creating muscle fibers could bring us a step closer to lab-grown organs for transplant.

One of the challenges of growing organs in the lab is the difficulty creating multi-layered structures of living cells. To overcome this obstacle, a team from EMPA developed gelatin sheaths for the cells, which protect them during the electrospinning process. The gelatin-encased cells were injected into to the scaffold using a process called electrospraying, resulting in a multi-layered structure embedded with living cells that could grow to form muscle fibers.
