[1, 0 lattice spacing of skeletal muscle during postnatal growth in mice]

1, 0 lattice spacing of extensor digitorum longus muscles of mice (ICR) during growth (2-12 weeks) were measured in situ by X-ray diffraction method. 1, 0 lattice spacing of EDL was 35.4 +/- 0.27 (mean +/- SD, N = 33) nm. No significant difference between spacings in EDL's of each aged mice was observed.
