Fig 1: Nlrp3 deletion does not alter the surface marker expression but promotes the osteogenic differentiation of MSCs. (a) Flow cytometry analyzed WT MSCs and Nlrp3 KO MSCs for surface markers (CD45, CD34, CD29, CD44, CD49e, and Sca-1). (b) Osteoblasts were stained by Alizarin Red S. (c) Adipogenic staining by Oil Red O. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
