Background & Aims: Intratumor heterogeneity is a common feature of colorectal cancer (CRC). Here. we analyzed whether mesenchymal-like CRC cells promote the progression of epithelial-like CRC cells via paracrine mechanisms. Methods: Six CRC cell lines that show an epithelial phenotype were treated with conditioned media (CM) from CRC cell lines that show a mesenchymal phenotype. https://www.infonoticiasgandia.com/product-category/disposable-lids/
