Fig. 2 — Retinal vascular density and acellular capillaries among groups. Retinal flat-mount digestion showed vascular density was improved after BMSC or Conbercept injection. Acellular capillaries (arrows) appeared in OIR-blank and OIR-DMEM but reduced in OIR-BMSC and OIR-CON. Quantification revealed significant improvement in the groups receiving BMSC or Conbercept injection (P17). *, P < 0.05 versus OIR-blank; n = 9; Bar = 20 μm
