NCIt definition : The intercalated cell is an epithelial cell of the renal collecting tubule that is
specialized for H and HCO3 transport. These cells exist in two types, [alpha] and
[beta]. The [alpha] cell secretes H into the lumen by an apical H ATPase and a basolateral
Cl:HCO3. The [beta] cell secretes HCO3- into the lumen by an apical Cl:HCO3 and a
basolateral H ATPase.;
