Solute permeabilities of the mouse CCD

Principal cells (x 10−5 cm s−1) Type A cells (x 10−5 cm s −1) Type B cells (x 10−5 cm s−1)
Apical Basolat Apical Basolat Apical Basolat Paracellular pathway (x 10−5 cm s−1)
Na+ 0.67 0 0 0 0 0 0.35
K+ 2.50 0.60 0.3 0.125 0 0.015 1.05
Cl− 0 0.002 6 0.50 0 0.40 0.42
HCO3 − 0 0.0004 0 0.10 0 0 0.084

‘Apical’ and ‘basolat’ denote the apical and basolateral membranes of each cell type. Basolateral chloride permeability values correspond to pHi 7.40; see Eqn (12).
