Table 2.

Percentage of Cells Expressing Voltage-Gated Potassium Currents

		K_A	K_DR	K_IR			K_A	K_DR	K_IR
NG2	Control	25% (8/32)	75% (24/32)	0% (0/32)	O4	Control	100% (8/8)	100% (8/8)	75% (6/8)

	3d SCI	59% (19/32)	100% (32/32)	0% (0/32)			83% (12/14)	100% (14/14)	100% (14/14)

Not all cells displayed all voltage-gated potassium currents. There was an increase in the percentage of NG2 cells expressing KA and KDR after injury. No NG2 cells expressed KIR. There was a decrease in the percentage of O4 cells expressing KA after injury, and an increase in KIR. Eighty-eight cells were analyzed: N = 32 NG2 cells (control), N = 32 NG2 cells (injured), N= 8 O4 cells (control), N = 16 O4 cells (injured).
