Fig. 4From: Albumin alleviated esketamine-induced neuronal apoptosis of rat retina through downregulation of Zn2+-dependent matrix metalloproteinase 9 during the early developmentEffect of albumin on zinc after esketamine exposure. A Representative images show Zn2+ accumulation in retina by the fluorescent Zn2+ sensor zinpyr-1. All images were taken at the same exposure. Scale bar, 100 μm. B The summary graph quantifies the intensity of zinpyr-1 signal in the GCL (n = 4 retinas per group). *** P < 0.001 compared with non-albumin groupBack to article page
