Group	Genotype of pups	Diet pregnant mothers placed on	Diet pups placed on	No. of pups examined (M+F)
A	WT	control	control	9 (6+3)
B	asj	control	control	10 (5+5)
C	asj	control	High Mg	11 (6+5)
D	asj	High Mg	control	13 (6+7)
E	asj	High Mg	High Mg	12 (6+6)

¹⁾ The pregnant mothers were placed on either control diet or magnesium-supplemented diet (high Mg diet) during pregnancy and nursing. The pups, at 4 weeks of weaning, were assigned to either control diet or high Mg diet for additional 10 weeks. The mice were sacrificed at the age of 14 weeks for mineralization analysis. WT, wild type; M, male; F, female.
