H-2 Haplotype No Data  
ES cell line CCE/EK.CCE [129S/SvEv-Gpi1]  
Background strain No Data  
 1 Appearance No Data  
Genotype No Data  
Strain development Developed by Motoya Katsuki, Institute of Medical Science, University of Tokyo. CCE/EK.CCE ES cells were used. The mutant mice were backcrossed to C57BL/6 by Naohiro Hashimoto, National Center for Geriatrics and Gerontology.  
Strain description dystrophin (Dmd) gene knockout mice. The exon 52 was replaced with a neo cassette. Mutant mice show hypertrophic skeletal muscles. Homozygous female and hemizygous male mutants are viable and fertile. The mice are difficult to start breeding at 8-10 weeks (12-16 weeks is better).  
Colony maintenance Homozygote (female) x Hemizygote (male) [or Crossing to C57BL/6JJcl]
