Ratios of AQP1-positive DTL and ATL profiles in transverse sections at 500 and 2,000 μm below the outer medullary-inner medullary boundary for kangaroo rat (n = 3 males, 3 females) and Munich-Wistar rat (n = 4 males). Kangaroo rat values are not significantly different from each other. Munich-Wistar rat values are significantly different from kangaroo rat values at each level and from each other at the two levels (two-way ANOVA/Scheffé tests, P < 0.05). These data are included in Fig. 4.
