Adhesion and proliferation of rMSCs on the shell and core scaffolds. (A) Cell adhesion and proliferation on the shell scaffolds were demonstrated by SEM (A1 and A2), hematoxylin and eosin (H&E) staining (A3) and fluorescence staining (A4–A6). (B) Cell adhesion and proliferation on the core scaffolds were demonstrated by SEM (B1 and B2), H&E staining (B3) and fluorescence staining (B4–B6). Blue = DAPI staining for Nucleus. Red = scaffold (autofluorescence of genipin). Red arrows: cells. Scale bar = 100 µm.
