Figure S3. EGFR silencing in HPAECs decreases their angiogenic ability and increases cell death.

HPAECs were transfected with either siEGFR or siCTL and were exposed to normoxia (left panel) or hypoxia (right panel) for 24 h. (A, B) Angiogenesis was assessed by tube formation assay (A), and apoptosis was measured by flow cytometry (B). (C) Egf, Egf-Hb, and Tgfa were measured in the lungs of hypoxic mice. Data are shown as mean. **P < 0.01.
