1. A population of modified Natural Killer (NK) cells, comprising a reduced Signal Regulatory Protein Alpha (SIRPα) function when compared to an NK cell population having an unmodified SIRPα function, wherein said modified NK cells effectively kill a population of cancer cells that express CD47 in an in vitro NK assay.
