Fig. 1From: Gain of CXCR7 function with mesenchymal stem cell therapy ameliorates experimental arthritis via enhancing tissue regeneration and immunomodulationCXCR7 is upregulated in MSCs during the induction of osteogenic and chondrogenic differentiation. a Cell surface co-expression of the antigens, CD44, CD73, CD90, and CD105 in MSCs. b Differentiation potential of MSCs in osteogenic, chrondrogenic, and adipogenic lineages using Alizarin red, Alcian blue, and oil red O staining, respectively. The mRNA levels (c) and cell-surface expression (d) CXCR7 in MSCs incubated with osteogenic or chondrogenic induction medium for 48 h. Data are means ± SD (n=9). *P < 0.0001 compared to the normal (untreated) groupBack to article page
