Figure Lengend Snippet: In vitro cytocompatibility and immunomodulatory effects of different samples on macrophages. (A) Representative images of RAW264.7 cells cultured for 48 h on different substrates, stained for actin filaments (red) and nuclei (blue). (B) Immunofluorescent staining of M1 marker CD86 and M2 marker CD206 after 48 h under LPS stimulation. (C–D) Quantitative analysis of CD86 and CD206 fluorescence intensity. (E–H) Secretion levels of TNF- α , IL-1 β , IL-6, and IL-10 determined by ELISA after 1 and 3 days of culture. (I–L) Relative mRNA expression levels of TNF- α , IL-1 β , IL-6, and IL-10 determined by RT-qPCR. Error bars represent means ± SD for n = 6, ∗ p < 0.05, ∗∗ p < 0.01.
