Summary of effects of VEGF pretreatment on subsequent ATP (100 uM)-induced [Ca2+]i bursts in intact UA Endo from luteal phase and pregnant sheep. The incidence of [Ca2+]i bursts was determined for 40 or more individual cells per field in replicate data sets from n = 6–8 ewes. Average percentages of cells responding with each successive burst in vessels without or with VEGF165 pretreatment are shown for nonpregnant luteal (top) and pregnant (bottom) UA Endo. Data are means ± SE of UA Endo from 6 to 8 ewes. *P < 0.05, compared with no VEGF pretreatment.
