SCF shRNA ameliorates degeneration of retinal ganglion cells (RGCs) in diabetic retinopathy (DR) mice. Day-30 after STZ administration, mice were injected intravitreously with AAV5-packed SCF shRNA (“shSCF-AAV5”, at 0.1 μL) or AAV5-packed scramble shRNA control (“shC-AAV5”, at 0.1 μL). After another 60 days, NeuN-positive RGCs in GCL were detected (A and B, scale bar = 50 μm). The listed human tissues were homogenized and mRNA and protein expressions of SCF and c-Kit were examined (C-E). “Mock” refers to mice administered with citrate buffer. “GCL” is the ganglion cell layer; “ONL” is the outer nuclear layer; “INL” is the inner nuclear layer. * P< 0.05 (A and B). * P< 0.05 vs. “Ctrl” tissues (C-E).
