Strain description Photo of SCG/Kj mice

The SCG/Kj mouse strain, a.k.a. SCG/ThpNkc, is an inbred strain known as a mouse model for rapidly progressive glomerulonephritis. The strain was established by sib mating of mice produced by mating between a BXSB/MpJ (BXSB) female to an MRL/MpJ-lpr/lpr (MRL/lpr) male. SCG/Kj mice develop crescentic glomerulonephritis and ANCA-associated vasculitis, which are not observed in BXSB and MRL/lpr, and die earlier than BXSB and MRL/lpr. These differences may be due to the presence of the autoimmune-promoting gene lpr (Faslpr) derived from MRL/MpJ-lpr/lpr, as well as the genetic background of BXSB/MpJ.

Method of strain maintenance

Mating should begin at 6 weeks of age because some females of the SCG/Kj strain develop glomerulonephritis and vasculitis at approximately 8 weeks of age. To maintain the incidence of the disease, we routinely test the parents' urine for protein and blood (e.g., urine test sticks, Eiken Chemical Co., Tokyo, Japan) after weaning of the pups, and among the urine symptom-positive females, we identify the females with both renal crescent formation and vasculitis development and then select pups derived from the symptomatic females for the next generation.
