Hypoxic HPASMC produce transforming growth factor-β1 (TGF-β1) and insulin-like growth factor binding protein-3 (IGFBP-3). HPASMC were exposed to 1% or 21% O2 for 24 h. Cell culture media were assessed for TGF-β1 and IGFBP-3 by ELISA. Values were corrected for changes in volume and protein concentration and compared with media obtained from normoxic cells to determine fold increase. The data represent the means of 3 samples ± SD. *P < 0.05, fold increase in TGF-β1 or IGFBP-3 protein in 1% O2 vs. 21% O2.
