Strain Code 01C04 [C3H/HeJCr]
Origin and Characteristics
Received by NCI from Jackson Laboratory in 1983. The C3H parent strain was developed by LC Strong in 1920 from a cross of a Bagg albino female with a DBA male followed by selection for high incidence of mammary tumors. C3H/HeJ mice are used as a general purpose strain in a wide variety of research areas including cancer, immunology and inflammation, sensorineural, and cardiovascular biology research. A spontaneous mutation occurred in C3H/HeJ sometime between 1960 and 1968 at lipopolysaccharide response locus (mutation in toll-like receptor 4 gene, Tlr4 lps) making C3H/HeJ mice endotoxin resistant while the other C3H strains are endotoxin sensitive.
