FIG 7.

(A) HE staining of gastroc from the matched hom DMSXL mice (6-week-old males), produced by the vehicle- or TG-treated DMSXL females. The matched WT littermates, produced in the vehicle-treated families, were analyzed as a control. The scale bar is 50 μm. Note the presence of small fibers in the gastroc from hom DMSXL mice, produced by the vehicle-treated females. (B to D) The gastroc weights, determined as a percentage of whole body weight (B), the average cross-sectional fiber areas (C), and the average numbers of fibers per ×10 view (D) were compared in gastroc from 6-week-old hom DMSXL mice (males) produced by DMSXL females treated with the vehicle or TG during gestation. Two mice per group were analyzed. The fiber area and the number of fibers in the vehicle-treated mice were corrected to the gastroc weight. NS, nonsignificant change.
