Fig. 1From: LPS-preconditioned mesenchymal stromal cells modify macrophage polarization for resolution of chronic inflammation via exosome-shuttled let-7bCharacterations of LPS pre-MSCs. a Representative photomicrographs of UC-MSCs and LPS pre-MSCs in culture displaying similar spindle shaped morphology. Scale bar 100 μm. b LPS pre-MSCs differentiation into adipocytes and chondrocytes. c Immunophenotype of LPS pre-MSCs by flow cytometry. d After appropriate LPS stimulation, UC-MSCs apoptosis didn’t show clearly change by flow cytometry analysis of Annexin V and 7-AAD staining. Data are presented as the mean ± SEM of three separate experimentsBack to article page
