Fig. 2From: Water-pipe smoking promotes epithelial–mesenchymal transition and invasion of human breast cancer cells via ERK1/ERK2 pathwaysWPS stimulates epithelial–mesenchymal transition (EMT) of breast cancer cell lines, MCF7 and BT20. We note that treatment for 3 days with 200 μg/ml of WPS solution induces morphological changes from “epithelial-like” (control) cells into “fibroblast-like” (mesenchymal) phenotype, which is known as EMTBack to article page
