Caption : fig. s1. ecg intervention on raw264.7 cells at different stages of ox-ldl induction. (a) the effect of ecg on the viability of raw264.7 cells. (b) oil red o staining was used to determine lipid accumulation in ox-ldl-induced raw 264.7 cells at different times after ecg intervention, magnification ×40. (c) quantitative analysis of oil red o staining results. (d) determination of tc content in the cell supernatant. all data are expressed as means ± s.e.m. ##p < 0.01 or ###p < 0.001 compared with the control group (n=3). **p < 0.01 or ***p < 0.001 compared with the corresponding time ox-ldl, i.e. ecg-12/48 vs ox-ldl-12/48.
