Hyperoxia impairs preterm ECFC growth and VEGF treatment increases growth in room air and hyperoxia. A: Growth curves of preterm ECFCs in room air or hyperoxia (40–50% oxygen) with or without recombinant human (rh)VEGF (25 ng/ml). Cells were grown in the following conditions for 6 days: room air without VEGF (RA-V; •); room air with VEGF (RA+V; ▪); hyperoxia without VEGF (HO-V; ○); and hyperoxia with VEGF (HO+V; ⧫). B: ECFC numbers on day 6. Hyperoxia reduced preterm ECFC growth, and VEGF treatment significantly increased ECFC growth in both room air and hyperoxia. Error bars represent SE. *P < 0.05, **P < 0.01. n = 4.
