Fig. 2From: Mesenchymal progenitor cells from non-inflamed versus inflamed synovium post-ACL injury present with distinct phenotypes and cartilage regeneration capacityPhenotypic characterization of synovial MPCs. Flow cytometry was employed to quantify the expression of the MPC+ (CD105, CD90, CD73, CD44) and MPC− (CD45, CD11b) cell surface markers (A). The relative expression of each marker was quantified within each group and compared between groups (B). No differences in any marker were observed between ACL-I groups. Adipogenic (C), osteogenic (D) and chondrogenic (E) differentiation was assayed by qPCR expression using lineage specific markers. n.s. = not significant; *p < 0.05Back to article page
