Cell uptake experiments. (A). Cell-associated radioactivity of [⁶⁸Ga]Ga-PSMA was measured after 1 h (light blue) and 4 h (dark blue). (B). Cell-associated [¹⁷⁷Lu]Lu-PSMA was measured in TNBC cells after 4 h. Cells were cultured before under normoxic (green) or hypoxic (pink) conditions. Additionally, HUVEC co-cultured for 96 h with TNBC under normoxia were measured after 4h (blue). Data are presented as mean ± SEM (n = 3). *** p ≤ 0.001; ** p ≤ 0.01; n.s. p > 0.05.
