Collaborative Cross mice (CC mice) are series of inbred mice strains generated from hybrid strains of mice with different genetic background which used for human complex diseases and genetic diversity diseases studies. Genetic diversity of CC mice can reflect different mouse subspecies, the single nucleotide polymorphism is four times than traditional inbred mice. CC mice are more and more widely used in the field of life science and medical research. Based on information retrieval of CC mice, we introduced the related information resources of CC mice origin, database, application tools, and research results, to promote CC mice resources to be used widely in China.
