FMC does not significantly impact cell death or mitochondrial substrate-supported respiration in BRECs. (a, b) FMC (0% FBS, 24 h) does not significantly increase cell death. Basal media is comprised of only MCB131 media without the addition of growth factors or supplements (m8537). Positive control (Pos ctl): 50°C for 10 min. (c) Time course of cell death assay. (d) Respiratory activity of BRECs cultured in control or FMC media after 24 h, **p<0.01, ***p<0.001, Data are represented as mean ± SEM. Scale bar, 10 µmol/l O2. Ctl, control
