Mean ± SE maternal saphenous and uterine vein serum E₂ levels and placental, maternal, and fetal body weights on day 60 of gestation in baboons untreated or treated daily on days 25 to 59 (term, 184 d) with E₂ (25 µg/kg body weight/d SC) or on days 25 to 59 with E₂ (25 µg/kg body weight/d) plus VEGF DNA delivered by CEU/MB to PBP on days 25, 35, 45, and 55.
