Fig. 2.

Representative images of ZnT3⁺ neurons located in OSP of porcine jejunum. All images are composites of merged images taken separately from the blue, red, and green fluorescent channels. a ZnT3 (red) neuron labeled for NOS (green) but SOM (blue)-immunonegative (two small single arrows), and ZnT3 (red) neuron labeled for SOM (blue) but NOS (green)-immunonegative (two single arrows). b ZnT3 (red) neuron labeled for VAChT (green) and VIP (blue)-immunopositive (two small double arrows). c ZnT3 (red) neuron labeled for SP (green) and VIP (blue)-immunonegative (small arrow).
