NK cells cultured in reoTCM are activated against melanoma cell targets. (A) NK cells were cultured in the presence of virus-filtered reoTCM/non-reoTCM overnight and CD69 expression determined. (B) NK cells were cultured in the presence of filtered reoTCM or non-reoTCM for 48 hours and then co-cultured with Mel-888 tumour targets prior to CD107 and intracellular IFNγ assessment. Results shown are gated on CD56+ve/CD3-ve cell populations and are representative of 4 independent donors.
