Figure 1 Persistent tubulointerstitial damage in thrombotic microangiopathy (TMA) rats at day 17. ETB receptor-deficient TMA rats showed severe tubulointerstitial damage (A) compared to wild-type TMA rats (B) at day 17 (PAS, ×200).

Figure 2 Osteopontin (OPN) expression by damaged tubules in TMA rats at day 17. ETB receptor-deficient TMA rats (A) show greater expression of the tubular injury marker, osteopontin, compared to wild type TMA rats (B). Representative OPN-positive tubules are indicated by arrows (×200).

Figure 3 Disruption of the peritubular capillary network in TMA rats at day 17. JG-12 staining demonstrated greater peritubular capillary density in wild type TMA rats (B) than in ETB receptor deficient TMA rats at day 17 (A; ×200). Double-staining with PCNA (black) and JG-12 (brown) revealed occasional proliferating peritubular capillary endothelial cells (inset, ×400).
