In an aging population, the social impact of osteoarthritis (OA) can dramatically increase to become the most common musculoskeletal disease. However, at present, therapies are limited to palliative treatments or surgical ...
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 ...
