Effects of 24 h growth factor starvation on proliferation of mouse E14 striatal cells

	Growth factors at DIV 0		Growth factors at DIV 1
	cell no.	cluster no.	cell no.	cluster no.
EGF	42.5  ± 15.1	34.0  ± 3.5	51.2  ± 20.4	32.0  ± 5.8
FGF-2	99.7  ± 23.5	81.5  ± 23.6	113.7  ± 36.9	100.0  ± 34.2

Striatal cells were plated onto a poly-l-lysine–laminin substrate. The indicated growth factors were added either at the time of plating (DIV 0) or 24 h after plating (DIV 1). Values represent means ± SEM of total counts obtained from two different experiments.
