Upregulation of Transient Receptor Potential Canonical Type 3 Channel via AT1R/TGF-β1/Smad2/3 Induces Atrial Fibrosis in Aging and Spontaneously Hypertensive Rats

Figure 1

Atrial structural remodeling measured by H&E staining from WKY 4m-o, WKY 24m-o, SHR 4m-o, and SHR 24m-o rats. Representative H&E staining: (a) magnification ×4, (b) magnification ×400, and (c) magnified the blue grid from (b).
