Expression of VEGFA isoforms 121, 165, and 189 in cultured human airway basal cells. a PCR amplification of VEGFA isoforms in basal cells (n = 4). Lanes 1–4: examples of four independent basal cell cultures. VEGFA-121, VEGFA-165, and VEGFA-189 are expressed. Lane 5: negative control (no DNA added). b–d TaqMan analysis of VEGFA isoform expression in basal cells (n = 3) compared to complete airway epithelium (n = 3) using isoform specific probes. b VEGFA-121, c VEGFA-165, and d VEGFA-189
