The adhesion and proliferation of MSCs on three composites. SEM images (4 hours after seeding): (a) PLGA-nHA, (b) PLGA-MSN, and (c) PLGA-MSN/nHA; SEM images (24 hours after seeding): (d) PLGA-nHA, (e) PLGA-MSN, and (f and g) PLGA-MSN/nHA; (h) the cell adhesion rate measurement; (i) the viability and proliferation of cells on the composites were measured by WST-1. The MSCs were marked with red arrows. compared to the other groups, and .
