Effect of pore size of the RSF scaffold on BMSC behaviors. The first row is the SEM photographs of RSF scaffolds with large, medium, and small pore sizes. The second row is the HE staining of BMSCs on corresponding scaffolds after 21-day osteogenic differentiation. The third row is the immunohistochemistry (IHC) staining of OCN (one of the osteogenic biomarkers) after 21-day osteogenic differentiation. Asterisks indicate RSF scaffolds.
