Figure 1From: Assembly of the outer retina in the absence of GABA synthesis in horizontal cellsHorizontal cells transiently express GAD67 during early postnatal development. Retinal cross-sections from the G42 mouse in which horizontal cells (hc) and amacrine cells (ac) expressing GFP were immunolabeled for GAD67 during early postnatal development (P3 to P10) and at structural maturity (P21).Back to article page
