Figure 6. Identification of the BMECs and the effect of Dex on the viability of BMECs. (A) The immunofluorescence staining of CD31 and VWF was used to identify BMECs. (B) The effects of Dex (50, 100, 150, 200, 300 μM) on the cell viability were determined by CCK-8 assay. (C) The effects of hUCMSCs on the cell viability under 200 μM Dex stimulation were determined by CCK-8 assay. The data are presented as the means ± SD (n = 3). *p < 0.05, **p < 0.01, ***p < 0.001, compared with the Con group.
