The CIEA NOG mouse® was developed by Mamoru Ito of the Central Institute for Experimental Animals (CIEA) in Japan. The Prkdc scid mutation was identified by Mel Bosma of the Fox Chase Cancer Center in a C.B-17 congenic mouse population. This mutation was backcrossed onto the NOD/ShiJic strain at CIEA for at least eight generations. The Il2rg targeted mutation was developed by Dr. Kazuo Sugamura of Tohoku University by targeting the gene in ES cells derived from a 129 strain. Portions of exons 7 and 8 were replaced with a neo cassette. Targeted ES cells were injected into C57BL/6 blastocysts. Resultant chimeras were backcrossed onto the C57BL/6JJic background for at least eight generations. The CIEA NOG mouse® was developed by backcrossing the C57BL/6JJic-Il2rg line to the NOD/ShiJic-Prkdc scid line for a total of eight generations. The hIL2-NOG mouse was developed by microinjecting a transgene consisting of a DNA fragment containing human IL-2 cDNA under the control of the CMV promoter into zygotes of NOD/ShiJic-Il2rg mice. Founders were backcrossed to NOG mice to establish the hIL2-NOG line. Taconic received stock in 2014, and the line was derived through embryo transfer.
