Nanofiber Spheres Carrying Cells Injected Into Wounds to Grow Tissue
ScienceDaily (Apr. 17, 2011) — For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, but the cells live on to form new tissue.
A new approach to inject cells to form new tissues. Of course, we are still faced with the problem of whether or not the cells will be rejected (immune response), but we are one small step closer to getting them into the damaged tissue.
