Latency of tumors growing from clones transfected with TSP-1 antisense

Clone	TSP-1 level	μg TSP-1 per μg secreted protein	Latency, days
HT1080 (parent)	high	0.14	23 ± 2
HT-13	intermediate	0.034	15 ± 3*
HT-16	intermediate	nd	13 ± 4*
HT-18	low	0.0037	9 ± 1*
HT-23	low	0.0016	8 ± 2*

nd, visually similar to HT-13 but not specifically quantitated. 

*Significantly different from parental HT1080, n of 3 or 4, P < 0.02.
