Samples	Cells
	HUVE		HME
	Cell no.	% increase	Cell no.	% increase
Control	69,900 ± 1,000	100	49,900 ± 1,400	100
Angiogenin	93,000 ± 4,000	133	57,900 ± 1,400	116
bFGF	197,000 ± 3,600	282	67,700 ± 1,600	136
bFGF plus angiogenin	255,000 ± 5,000	365	80,800 ± 1,100	162

HUVE and HME cells, at 7 × 10⁴ and 5 × 10⁴ per 35-mm dish, were stimulated by angiogenin (1 μg/ml), bFGF (2 ng/ml), or a mixture of the two.
