Table 1. Colony formation of PrEC, LNCaP and PC cells in soft agar in the presence of PL.

Cell types Treatment No of colonies s.d.
PrEC No treatment 0 ±0
LNCaP No treatment 154 ±7.5
LNCaP PL (0.75 mg ml−1) 17 ±4
LNCaP PL (1.0 mg ml−1) 5 ±2
PC3 No Treatment 208 ±1.8
PC3 PL (0.75 mg ml−1) 106 ±8
PC3 PL (1.0 mg ml−1) 68 ±5

The cells were cultured in soft agar in the absence or presence of different concentrations of PL for 2 weeks. Every 3 days, fresh growth medium containing PL was added into the cultures. s.d.: standard deviation over five independent experiments.
