Fig. 6: Expression of channel proteins in salivary glands under various conditions.

a Expression of acinar (AQP5, shown as white arrow) and ductal (Na+/K+-ATPase) in control (mock radiated), irradiated, and irradiated + transplanted (2 mM Ca2+) salivary gland tissue sections and b confocal images showing expression of TRPC1 channels in control (mock radiated), irradiated, and irradiated + transplanted salivary gland issue sections. Images were taken using ×40 objective and scale bar = 50 μm.
