Growth of lung cancer cells in three-dimensional microenvironments reveals key features of tumor malignancy

Abstract excerpt

Cultured human lung cancer cell lines have been used extensively to dissect signaling pathways underlying cancer malignancy, including proliferation and resistance to chemotherapeutic agents. However, the ability of malignant cells to grow and metastasize in vivo is dependent upon specific cell-cell and cell-extracellular matrix (ECM) interactions, many of which are absent when cells are cultured on conventional...
