Fig. 3. Cellular co-localization of ACE-1/IL-1β and ACE-1/MCP1 in the kidney.

Central transverse sections were prepared from old wild type (O-WT) female mice and subjected to immunofluorescence staining of a ACE-1 (red) and IL-1β (green) or b ACE-1 (red) and MCP1 (green). Enlarged images were selected from outer medulla. Scale bar = 0.5 mm for upper panels in (a, b) and 0.1 mm for lower panels in (a, b).
