Fig. 5From: Tumor cell-derived conditioned medium induced pro-tumoral phenotypes in macrophages through calcium-nuclear factor κB interactionLL-2-CM decreased cytosolic calcium in BMDMs. BMDMs cultured with or without LL-2-CM were stained by cytosolic calcium probe Fluo-4-AM. The short-term alteration of cytosolic calcium within 6 h was detected by fluorescent plate reader A. The long-term alteration of cytosolic calcium after 48 h was detected by FCM B. P values were calculated by Student’s t-testBack to article page
