Peritubular capillary density (PTCD), evaluated after CD31 staining. IRI resulted in decreased PTCD at 48 h and 6 weeks, respectively. Native (non-transfected) EPCs increased the PTCD at 6 weeks but not earlier. Transfected cells however prevented the loss of capillaries completely (48 h and 6 weeks) (magnifications in b-d × 40; Data in a as mean +/− SEM; *: p-values between different groups of the ‘48 h cohort’ < 0.05 – the bracketed lines indicate comparisons between two groups; #: p-values between different groups of the ‘6 weeks cohort’ < 0.05 – the bracketed lines indicate respective comparisons)
