Atrial natriuretic peptide signal pathway upregulated in stomach of streptozotocin-induced diabetic mice

Figure 3 Flow cytometric analysis of ANP-positive cells among gastric mucosal cells. The percentage of ANP-positive cells was determined by flow cytometry with FITC-conjugated goat anti-rabbit IgG. A: Relative fluorescence intensity of gastric mucosal cells in the control and diabetic groups. M1 indicates the proportions of ANP-positive cells that displayed positive FITC labeling. The inserted fluorescent image is a single ANP-positive cell that had a positive fluorescent signal in its cytoplasm (× 400); B: ANP-positive cells among the gastric mucosal cells (10⁴ cells per sample) in control and STZ-induced diabetic mice (n = 3, ^aP < 0.05 vs control).
