Stem cell implants can fix broken bones

LONDON: Researchers have pioneered a new technique combining bone stem cells with a degradable rigid material to encourage real bone to regrow.

The material developed by the Universities of Edinburgh and Southampton is a honeycomb scaffold structure that allows blood to flow through it, enabling stem cells from the patient's bone marrow to attach to the material and grow new bone. The plastic slowly degrades as the implant is replaced by newly grown bone.
