Extended Data Fig. 1: Vascular expression of bPAC.

(a) Expression of bPAC (red, left) in two fields of view (top and bottom), compared with the tomato lectin vascular stain (green, right) in two fields of view from a different animal, showing similarity of labeled features as in Fig. 2b. Scale bar = 200 µm. (b) Images showing bPAC expression in individual cells spaced along individual vessels, analogous to Fig. 2c. Scale bars = 100 µm (top) and 200 µm (bottom).
