Figure 2: Immunofluorescent staining of angiotensin 1-7 (Ang 1-7; purple), ACE2 (red), and a nuclear marker (DAPI; blue) in kidney specimens (A, B, C). Merged images of Ang 1-7 and ACE2 (pink) staining showing the co-localization of ACE and ACE2 in the proximal tubules of a healthy control and an MCNS patient (A, C). The merged image of the proximal tubules of the diabetic nephropathy patient (B) is a completely different color from that of the healthy control (A).
