This video demonstrates an assay to generate anti-angiogenic tumor-associated neutrophils (TANs). Upon taking a murine melanoma tumor containing pro-angiogenic TANs, the single cells are isolated using fluorescence-activated cell sorting (FACS) and treated with an inhibitor of nicotinamide phosphoribosyl transferase (NAMPT) to reduce the capacity to stimulate angiogenesis.
Protocol
All procedures involving sample collection have been performed in accordance with the institute's IRB guidelines. NOTE: The overall scheme of the protocol is shown in the Figure 1. 1. Preparation of B16F10 melanoma cell line Prepare mycoplasma-negative cells grown to a 90% confluent monolayer (approximately 10 x 106 cells/T75 flask) in complete Iscove's Modified Dulbecco's Medium (…
