Figure Lengend Snippet: A Flow cytometry analysis revealing the proportion of CD163-positive cells in the SVF (n = 5). B Setup of the separated pellet co-culture system. Groups including ADSC, M2Φ, and SVF were established, with each administered cell type in membrane plates and OA chondrocytes in 15 mL tubes. A control group was established with no cells in membrane plates and only OA chondrocytes in 15-mL tubes. C Gross photographs and safranin-O staining of the resulting pellets in each group. D Comparison of pellet size among each group (n = 5/group). E Analysis of TGF-β, IL-10, and MMP-13 levels in the supernatant following coculture with ADSC, M2Φ, and SVF and the chondrocyte (n = 5/group). SVF, stromal vascular fraction; M2Φ, M2 macrophages; ADSC, adipose-derived stromal cell; TGF-β, transforming growth factor-β; IL-10, interleukin-10; MMP-13, matrix metalloproteinase 13
Article Snippet: The samples were incubated overnight at 4 °C with a conjugated primary antibody against F4/80 (1:100; orb466169-FITC, Biorbyt), conjugated primary antibody against CD163 (1:200; BS-2527R-A594, Bioss), and primary anti-mouse antibody against hNA (1:500; ab191181, Abcam).
