Figure Lengend Snippet: Effects of bare and coating-modified groups on SMCs proliferation. (A–C) Representative fluorescence images of HUASMCs cytoskeleton (red) and nucleus (blue) after 24 and 72 h of different treatments, including untreated control group, bare group, MgF 2 -coated group, MgF 2 /PU-coated group, and MgF 2 /PU/PTV-coated group (A), along with quantitative cell viability assessments at 24 h (B) and 72 h (C). (D–E) Relative mRNA expression levels of α-SMA (D), VCAM-1(E), as determined by qPCR analysis. One-way ANOVA followed by Tukey's multiple comparison test was performed to determine statistical significance. Data are presented as mean ± SD, with p -values <0.05 considered statistically significant (n = 3). ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001.

Figure Lengend Snippet: SMCs Shift phenotypic transition to synthetic type from contractile type orchestrated by ECs. (A) , LPS increased the migration ability of SMCs. When SMCs were co-cultured with ECs, the increased migration induced by LPS was alleviated.

Meanwhile, ECs could enhance the expression of SM22 and α-SMA in SMCs in normal condition. (B1 and B2) . Quantification of B is shown in B1 and B2, **: P<0.01, SMC Control vs SMC LPS, ##: P<0.01, #: P<0.05, SMC LPS vs CULSMC LPS; CULSMC Control vs CULSMC LPS, @@: P<0.01, SMC LPS vs CULSMC LPS; &: P<0.05, SMC Control vs CULSMC Control.

Figure Lengend Snippet: LPS induced a higher higher level of PDGFR-β and IQGAP1 in SMCs in both the single and co-culture systems. (A) , LPS induced the level of p-PDGFR-β expression in SMCs in both single and coculture system, but when SMCs were co-cultured with ECs, both control and LPS group experienced the relative lower p-PDGFR-β protein expression than that in single culture system. With LPS stimulation, p-PDGFR-β levels in co-culture SMCs were remarkably lower than those of single-culture SMCs. Quantification of A is shown in A1; **: P<0.01, SMC Control vs SMC LPS, #: P<0.05, CULSMC Control vs CULSMC LPS, @: P≤0.05, SMC LPS vs CULSMC LPS; (B) , the change of IQGAP1 expression was mediated by LPS, Quantification of B is shown in (B1) ; **: P<0.01, SMC Control vs SMC LPS, #: P<0.05, CULSMC Control vs CULSMC LPS, @@: P<0.01, SMC LPS vs CULSMC LPS.
