Two human (SKMEL28 and 1205Lu) and a murine (B16BL6) melanoma cell lines were exposed, or not, to the indicated EV from primary murine adipocytes obtained from lean mice fed a normal diet (ND) or obese mice fed a high fat diet (HFD), then FAO was measured (n =5 for B16BL6, SKMEL28 HFD EV and 1205Lu ND EV and n=6 for other conditions).
