Muscle fiber cross-sectional areas. Fiber cross-sectional areas (means ± SE) are presented for control and IUGR fetal semitendinosus and biceps femoris muscle sections. Control, open bars; IUGR, black bars. A: Type I fibers (MyHC-I positive); B: Types I or IIa fibers (MyHC-I/IIa positive); C: Type II fibers (MyHC-II positive); D: Type IIx fibers (MyHC-IIx positive) were determined by immunostaining. All sections were counterstained for desmin to determine total fiber numbers. *Differences (P < 0.05) between control and IUGR groups within each muscle.
