Quantitation of vascular sprouting inhibition by anti-PECAM1 antibody.^a

Day	Day 4			Day 8			Day 11

Treatment	No tx	Iso tx	PE tx	No tx	Iso tx	PE tx	No tx	Iso tx	PE tx
No sprouts	38,39	35,32	37,31	27,28	29,28	38,34^*	26,28	19,23	28,29
Sprouts <250 µm	51,48	53,57	55,51	38,39	41,39	42,45	29,28	33,27	23,28
Sprouts >250 µm	10,14	12,11	14,12	35,33	30,33	20,21^**	45,44	48,50	47,43

EBs were treated with 0 (No tx), 10 µg/ml of an isotype control Ab (Iso tx) or 10 µg/ml of anti-PEACAM1 antibody (PE tx) and the number of sprouts quantitated at days 4, 8, and 12 as follows: the number with no sprouts, the number with sprouts <250 µm, and the number with sprouts >250 µm. The experiment was repeated twice. All values were compared to the no treatment control by Student's T test (*, p<0.05,**, p<0.01).
