Characterization of a novel angiogenic model based on stable, fluorescently labelled endothelial cell lines amenable to scale-up for high content screening

Abstract

HMEC-based lines retain most of the angiogenic features of primary endothelial cells and yet possess long-term stability and ease of culture, making them intriguing candidates for large-scale primary HCS and HTS (of ~10000-1000000 molecules). Furthermore, inclusion of EMCs demonstrates the feasibility of using epicardial-derived cells, which normally contribute to smooth muscle, to model large vessel formation. In summary, the immortalized fluorescent HMEC and EMC lines and straightforward culture conditions will enable assay development for HCS of angiogenesis.
