Stem cells (red) on polycaprolactone-based microcarriers. Bone tissue engineering is theoretically now possible at a large scale. A*STAR researchers have developed small biodegradable and biocompatible supports that aid stem cell differentiation and multiplication as well as bone formation in living animal models. Mesenchymal stem cells self-renew and differentiate into fat, muscle, bone, and cartilage cells, which makes them...
