Additional file 3: of Retinal ischemia induces α-SMA-mediated capillary pericyte contraction coincident with perivascular glycogen depletion

Figure S3. The action of CBX was not mediated by inhibition of pericytic pannexin-1 channels. One hour after ischemia, pericytes (arrow) were yet not labeled with propidium iodide (PI) (A) whereas retinal Hoechst positive parenchyma cells were (B), suggesting that the action of CBX at the dose used was not mediated by inhibition of pericytic pannexin-1 channels. Scale bar in A = 10 μm; in B = 50 μm. (TIF 8380 kb)
