EDS was used to eliminate differentiated LCs in the isolated primary cells in this study. As shown in Figure S1, a part of primary cells dead when incubated with different concentrations of EDS (0, 0.5, 0.75, and 1.0 mg/mL). The dead cell percentage was approximately 23%, which showed that the percentage of differentiated LCs was approximately 23%, and the purity of primary isolated porcine SLCs was over 77% (Figure S1, S2). Then qRT-PCR results showed that the expressions of Nestin and CYP17A1 were statistically significance in 1.0 mg/mL EDS treated group than control group, which predicted that 1.0 mg/mL was the best treatment concentration of EDS in this study (Figure S3). At the foundation of this result, immunofluorescent analysis was used to detected the expression of CYP17A1 in the primary cells before and post EDS treatment. As shown in Figure S4, the percentage of CYP17A1-positive cells was approximately 25% before EDS treatment, which was consistent with the dead cell percentage. Meanwhile, the membrane structures of CYP17A1-positive cells were broke after EDS treatment, predicting that EDS could be eliminate porcine differentiated LCs in this study (Figure S4).
