Summary of PAS-positive staining

	WT (6–8 mo)	Gaa−/− (6–8 mo)	WT (12–15 mo)	Gaa−/− (12–15 mo)
Dorsal horn	0/4	2/4	0/4	4/4*
Intermediate gray	0/4	4/4*	0/4	4/4*
Ventral horn	0/4	4/4*	0/4	4/4*

The periodic acid Schiff (PAS) stain imparts a pink color in neurons considered positive (e.g., Fig. 1). The table depicts the proportion of Pompe (Gaa^−/−) and wild-type (WT) mice showing positive PAS staining in specifically defined regions (e.g., 4/4 indicates that 4 of 4 mice examined showed PAS positive neurons). Proportions were examined by Fisher's exact test.
