Table 1. Intracellular accumulation of ¹⁴C-FIAU and ³H-FAU in HSV-tk expressing and control MH3924A cells grown in culture.

Cell retention measured as percent of incubated dose/10⁵ cells and converted into selectivity index.

	MH3924A	MH3924A-stb-tk+	Selectivity index	P value
	% of incubated dose/10⁵ cells		Selectivity index	P value
FIAU	0.285	7.261	25.5	<0.0001
FAU	0.002	0.075	34.5	<0.0001
