The numbers of β-gal or PkcΔGG positive cells that contained TH-IR, in rats sacrificed at 1 month after co-injection of pTHlac/gC – bdnf and pHSVpkcΔGG/gC – bdnf into the midbrain
	Numbers of positive cells		%	Numbers of positive cells		%
Rat	β-gal-IR	TH-IR	Costained	Flag-IR	TH-IR	Costained

1	201	184	92	129	89	69
2	183	171	93	110	82	75
Average			93 ± 1			72 ± 3

This experiment was performed as in Table 1, except the rats were perfused at 1 month after gene transfer.
