EMT Reporter Cell Lines

New Tools for Metastasis Studies

11/15/2018

Epithelial-mesenchymal transition (EMT) describes a cellular process during which differentiated epithelial cells lose their epithelial features and gain mesenchymal properties. EMT has been implicated in the invasion-metastasis cascade hallmark of cancer; cells undergoing EMT display an ability to promote metastasis and elevated drug resistance. Therefore, an in vitro EMT reporter cell model is a valuable tool for dissecting EMT molecular pathways and screening therapeutic compounds. ATCC recently created novel EMT reporter knock-in cell lines by using CRISPR/Cas9 genome-editing technology. These EMT reporter cells faithfully recapitulate the endogenous EMT marker expression; in response to treatment, the reporter cells undergo EMT, enabling real-time monitoring of dynamic EMT intermediate states in live cells. Further, we present application data indicating that pathway- specific inhibitors can block EMT in a dose-dependent matter.
