Fig. 7From: Mesenchymal stromal cells secretome restores bioenergetic and redox homeostasis in human proximal tubule cells after ischemic injuryMetabolomics profile of ischemic ciPTECs in normoxia and hypoxia. Heatmaps of the key metabolites involved in fatty acid oxidation (FAO) (a, b), tricarboxylic acid (TCA) cycle (c, d), and glycolysis (e, f). Metabolite sets enrichment overview of ischemic N- ciPTECs (g) and H-ciPTECs (h), compared to sham, representing their physiological relevance. Heatmap results are shown as log2(FC) compared to the sham group. Red colors indicate increased values, while blue colors indicate decreased values. N, normoxia; H, hypoxiaBack to article page
