Growing stem cells on polymer scaffolds could be an effective strategy for manufacturing replacement tissues—a piece of bone to repair a defect or a fracture, for instance (SN: 3/6/04, p. 155: Available to subscribers at Body Builders). However, keeping the cells alive on the scaffold long enough to differentiate into specific cell types and to form new tissue remains a challenge.
