Fig. 1From: Placental extract suppresses the formation of fibrotic deposits by tumor necrosis factor alpha and transforming growth factor beta-induced epithelial–mesenchymal transition in ARPE-19 cellsEffect of placental extract on the viability of ARPE-19 cells. Cell viability was measured using the SRB assay. ARPE-19 cells were incubated with varying concentrations (0.4, 2.0, and 4.0 mg/mL) of placental extract, for 96 h. a pPE and b ePE treatments. Data are expressed as mean ± SD of three independent experiments performed in triplicateBack to article page
