Table 1.

Number of TNF-IR cells in the stimulated column under the microarray vs. unstimulated columns outside the microarray within layers of the Sctx. The data are expressed as mean ± SEM for 5 rats.

IMMUNOREACTIVITY IN SCTX LAYERS		TREATMENT
		STIMULATED	UNSTIMULATED
TNFα-IR	Primary Sctx-II–III	12.3 ± 4.1*	7.9 ± 2.8
	Primary Sctx-IV	22.7 ± 5.9*	13.6 ± 5.0
	Primary Sctx-V	28.3 ± 3.2	30.5 ± 5.2
