Additional file 1: Fig. S1. MOCK and hEPO-KMSC characterization. Flow cytometry analysis of cell surface marker expression on cells. Red lines indicate CD29, CD44, CD45 and CD73 expression. Black lines indicate isotypic controls. Fig. S2. Fluorescence microscopy of frozen obstructed kidney tissue sections showing red CellTracker™-labeled MPs colocalized within the interstitium. White arrows indicate red CellTracker™-labeled MPs. Fig. S3. RT-PCR analysis of hEPO mRNA expression. Compared to hEPO-MPs, MOCK-MPs failed to induce hEPO mRNA expression. (PPTX 1940 kb)
