Fig. 1From: Nerve Growth Factor Prevents Both Neuroretinal Programmed Cell Death and Capillary Pathology in Experimental Diabetes Effect of diabetes on programmed cell death in the retina Histochemical labeling of DNA fragmentation in vertical cryostat sections (7 µm) using the Apoptag kit. Sections from nondiabetics (a) do not show PCD, while sections from diabetics (b) show PCD in the ganglion cell layer (arrowhead) and in Muller cell-containing inner nuclear layer (arrow).
