K− c-Src completely ablates tumor formation in nude mice in 10T½ clones

Cell line	Tumor volume,* mm3
EGFR8	295  ± 124
EGFR/K+9	1,592  ± 598
EGFR/K−	0†

^*Mean tumor volume ± SEM of eight individual sites was measured at day 52 after subcutaneous injection. 

^†EGFR/K− represents the mean tumor volume of two individual clones, EGFR/K−₄₁ and EGFR/K−₅₆.
