Figure Lengend Snippet: The regulatory effects of CaHA/PLGA microspheres on macrophages and ADSCs in vitro. (A, B) CLSM images and RFI of CD86 and CD206 expression in RAW264.7 cells co-cultured with microspheres for 2 days (n = 3). (C–F) Relative mRNA expression levels of inflammation-related genes TNF-α, IL-6, TGF-β1, and FGF-2 in RAW264.7 cells (n = 3). (G, H) Sirius red staining images and quantitative analysis (n = 3) of collagen deposition of ADSCs co-cultured with CaHA/PLGA microspheres for 3 and 7 days. (I–K) Relative mRNA expression levels of TGF-β1, FGF-2, and PDGF-A in ADSCs after 3 and 7 days of co-culture with CaHA/PLGA microspheres (n = 3). ∗ p < 0.05; ∗∗ p < 0.01; ∗∗∗ p < 0.001; ∗∗∗∗ p < 0.0001; ns , not significant.
Article Snippet: CD86 polyclonal antibody (1:200, 13395-1-AP, Proteintech), CD206 (1:200, 18704-1-AP, Proteintech), and TNF-α recombinant antibody (1:200, 80258-6-RR, Proteintech) were used as primary antibodies, incubated overnight at 4 °C.
