Table 1.

Wet weights of rat UGM alone, wild-type and PSMA-transgenic prostate tissue recombinants after 8, 16 and 24 weeks of kidney grafting in intact male nude host mice treated with testosterone and estradiol. There was no difference in wet weights of wild-type and PSMA-transgenic tissue recombinants. Wet weights of both tissue recombinants declined significantly with serial grafting.

	rUGM only	Wild-type tissue recombinants		PSMA-transgenic tissue recombinants
8 weeks	19.2 ± 4 mg (11)	103.2 ± 5.2 mg (9)		90.2 ± 7.4 mg (20)
16 weeks	30.4 ± 5.2 mg (7)	70.8 ± 11.4 mg (10)		59.6 ± 6.5 mg (26)+
24 weeks	19.7 ± 3.9 mg (8)	57.3 ± 8.3 mg (27)+		62.8 ± 8.7 mg (32)*
