I-SceI-induced gene replacement at a natural locus in embryonic stem cells.

abstract：:Transfection of C3H/10T1/2 cells with a c-myc gene resulted in the acquisition of responsiveness to transforming growth factor type beta. Cells transfected with an activated H-ras gene or an H-ras and c-myc gene, however, exhibited a transformed morphology and spontaneous soft-agar growth, a phenotype induced reversib...
