<p>(A) NBCe1 and NBCn1 mRNA transcripts in hSMG and HSG cells. Aquaporin 5 (AQP5) was used as a marker for acinar cells. (B and C) hSMG tissue sections were stained with NBCe1, NBCn1, and AQP5 antibodies. (Bar = 50 μm). AQP5 was used as a marker for acinar cells. White and yellow arrows indicate acinar cells and duct cells, respectively. NBCe1-B is expressed in human submandibular gland (hSMG) duct cells, whereas NBCn1 is expressed in acinar (white arrow) and duct cells (yellow arrow). (D and E) HSG cells were stained with antibodies for NBCe1 and NBCn1. (Bar = 20 μm).</p
