Histological staining images of cell-seeded microsphere-based constructs at week 6. BLANK, TGF, and DCC scaffolds were stained for H&E, Safranin-O, Masson’s trichrome, and Sudan Black. No images could be obtained from the CS group as the sections washed off the slides during the staining process. The Sudan Black staining intensities for residual polymer were higher in the BLANK and TGF groups compared with the DCC group. Scale bars: 100 μm.
