Relative abundance of the various cells types along the collecting system in kidneys from control mice and mice treated with KCl, NH4Cl, or NaHCO3.

Values are means ± SE, with the number of cells counted in parentheses. Shown is a summary of cell counts in the different segments of the collecting system, 5 animals in each group were analyzed, and cells were counted. CNT, connecting tubule; CCD, cortical collecting duct; OMCD, outer medullary collecting duct; IMCDi, initial segment of the inner medullary collecting duct. Significant difference between control and treatment groups:*p**p***pKidney sections from animals receiving sucrose (control), NH4Cl, KCl, or NaHCO3 for 7 days were stained for AE1, pendrin, AQP2/calbindin D28k, and DAPI and cells counted for the various markers and distinct segments. The total number of cells counted is given in brackets, for each condition n = 5 animals were counted.
