Quantification of CD31+ sprouting angiogenesis. Percentage of day 7 (a) or day 14 (b) EBs with either CD31+ sprouts or CD31+ sheets. Average CD31+ sprout length from day 7 (c) or day 14 (d) EBs, normalized to Scr1 values. Bars are means ± S.E.M. (Scr1 and Scr2, scrambled siRNA sequences; KD1 and KD2, knock-down siRNA sequences; n = 10 and 12 for controls, n = 15 and 9 for knockdowns).
