Table III. Slit2 enhances migration of trunk, not vagal, neural crest cells.

	Control	Slit2
	μm	μm
Trunk	133 ± 3.8	161 ± 4.2	21%a
Vagal	132 ± 7	125 ± 6	−6%

Neural tubes were cultured overnight on fibronectin. Values correspond to the average distance traveled by the neural crest cells away from the neural tube explant ± SEM. For trunk, there were a total of >100 neural tubes per condition in 12 separate experiments. For vagal, there were 12 neural tubes per condition in three separate experiments.
