Figure 7. PDGF-BB significantly increased infiltration of human synovial cells into the scaffolds.

Figure 7.

(A) Representative histologic images of core-shell nanofibers with human synovial cells: H&E, Safranin O Fast Green, DAPI, and PDGFRβ immunostaining (Mag.: 40x; scale bar: 100 μm). (B) Number of synovial cells infiltrated into core-shell nanofibers. Line= P < 0.05 between groups, *=P < 0.05 between each cell type.
