Gas exchange adequacy of microvessels. (A) Representative image of cell culture media after 6 days of culture with and without microvessels. (B) Absorbance of phenol red in cell culture media and (C) absorbance ratio (560 nm/505 nm) of phenol red in cell culture media. (D) Expression of HIF1α levels in THP-1, Jurkat, MDA-MB-231 and Fibroblast cells cultured with PDMS microvessels relative to control samples cultured without microvessels. Data are presented as mean ± SD. Experiments were performed in at least 4 replicates.
