JPC proliferation within collagen/HA (1:2) composites. Collagen/HA composites in a ratio of 1:2 were prepared with (-pep) or without E7 BMP-2 peptides. JPCs were cultured within the composites under normal (Co) and osteogenic (Ob) conditions for 4–28 days (at least three independent experiments). Metabolic activities after these time points are illustrated. * p < 0.05.
