Fig. 4

a Schematic of the normothermic perfusion system for diagnostic assessment of fresh untreated (control), 24-h UW preserved (24 h), VMP loaded-unloaded (VMP), VS55 loaded-unloaded (VS55), and vitrified and nanowarmed (V–N) rat kidneys. b Cumulative urine output over the course of perfusion. c Creatinine clearance. d Alterations in renal artery flow. e Oxygen consumption rate. f Venous pH. g Vascular resistance. h Lactate production. i Glucose consumption. Data are mean ± s.d. n = 4 per condition. Statistical comparison between nanowarmed kidney and other treatment groups at minute 40 using ANOVA and Tukey HSD (Games–Howell if unequal variance) post hoc tests. *P < 0.05, **P < 0.01, ***P < 0.001; NS, not significant. Full statistical treatment in Supplementary materials. Source data are provided as a Source Data file. OCR oxygen consumption rate; V–N, vitrified and nanowarmed.
