Nanofiber Spheres Carrying Cells Injected Into Wounds to Grow Tissue

Image
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.

Developing this nanofiber sphere as a cell carrier that simulates the natural growing environment of the cell is a very significant advance in tissue repair, says Peter Ma, professor at the University of Michigan School of Dentistry and lead author of a paper about the research scheduled for advanced online publication in Nature Materials. Co-authors are Xiaohua Liu and Xiaobing Jin.
