Agar colony formation by CEF infected with LEF-1 fusion constructs

Infecting construct	Colonies per 104 cells
	Exp. 1	Exp. 2
Vector (RCAS)	0.4	1.7
LEF-1	(70)*	(70)*
LEF-1-VP16	79	200
LEFΔN-VP16	8.3	15
LEFΔN-βcat	64	60
LEFΔN-βΔN	53	53

^*Colonies induced by LEF-1 remained very small (see Fig. 5 Lower).
