Fig 6. Semi-quantification of aquaporin-4 labeling in 6 regions of porcine ONH region.

Values in choroid, sclera, and lamina are minimal, not significantly different from each other, while each was significantly lower than retina, myelin transition zone (MTZ), and myelinated optic nerve (MON). Mean ± standard errors. Dotted line identifies the AQP4 background level in choroid. †p < 0.05, ††p < 0.01 for difference from control choroid. *p < 0.05, **p < 0.01 for difference from lamina.
