Effects of H₂O₂ on bovine PAEC and RPMEC growth. (A) Bovine PAEC (BPAEC) were treated with varied concentrations of H₂O₂ for 48 h in medium containing 2% FBS. (B) BPAEC were treated with 1 μM H₂O₂ for 48 h in medium containing 0 or 2% FBS. (C) RPMEC were treated with varied concentrations of H₂O₂ for 48 h in medium containing 2% FBS. The number of cells was determined by Coulter counting. Values represent means ± SE, n=3. ^∗Values differ from the 0 μM H₂O₂ control at p<0.05.
