Figure 6. CD14 deficiency led to partial TLRs stimulation in MSCs.

(A) Human PBMC and different sources of MSCs were stained with CD14 and isotype control and analyzed by flow cytometry. CD14, black; isotype control, gray. (B) Murine peritoneal macrophages and BMSCs were also treated like (A). (C) Murine peritoneal macrophages and BMSCs were stimulated with LPS (1 μg/ml) for different times. And the molecular signals were analyzed by Western blot.
