Boiling histotripsy-induced breast cancer cell death stimulates M1 macrophage polarisation. (a) The morphological changes of macrophages from M0 to M1 like cells after co-cultured with the supernatant of the boiling histotripsy-treated breast cancer cells. A scale bar represents 100 μm. (b) Increases of M1 macrophage-related markers and decreases of M2 macrophage-related markers are shown. 50 boiling histotripsy pulses were used. (c,d) Reprogramed macrophages, from M2 to M1 like, after cultured with the supernatant obtained from the boiling histotripsy-treated cancer cells. CON = Control group (i.e., no boiling histotripsy exposure). BH = Boiling histotripsy. *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001 and ****p ≤ 0.0001.
