10">Distributions of pAQP0 and pMP20 change with age and across human lens regions.
15">MP20 pSer170 peaks in the cortex and decreases with lens age in the nucleus.
AQP0 pSer235 peaks in the inner cortex and declines with lens age in the nucleus.
A decrease in AQP0 pSer235 in aged lenses correlates with the permeability barrier.
AQP0 pSer229 is minor, but levels remain steady into the nucleus and with lens age.
