Transforming potential of BCR-ABL-GFP vs. BCR-ABL-GFP + N17 H-Ras

Cells	Assays	BCR-ABL-GFP*	BCR-ABL-GFP + N17 H-Ras*	GFP vector*
NIH 3T3	# of foci	117 +/- 16†	11 +/- 2	-
Bone marrow	# of colonies	16 +/- 0.6	0.33 +/- 0.33	-

* Retroviral titers were matched.

†Results are shown as the mean ± SD of three independent experiments.
