Description

These NSG-porcine cyokine mouse mutant mice may be useful for long-term porcine tissue and stem cell engraftment and transplantation research.

Detailed description

These mutant mice carry the Prkdc^scid and Il2rg^tm1Wjl alleles and the Tg(IL3)1Ygy, Tg(CSF2)2Ygy and Tg(KITLG)3Ygy transgenes. The Tg(CSF2)2Ygy transgene contains the porcine colony stimulating factor 2 (granulocyte-macrophage) sequence (CSF2) under the control of the human cytomegalovirus promoter. The Tg(IL3)1Ygy transgene contains the porcine interleukin 3 sequence under the control of the human cytomegalovirus promoter. The Tg(KITLG)3Ygy transgene contains the porcine kit ligand (KITL) under the control of the human cytomegalovirus promoter. The 3 transgenes were coinjected together in the original transgenic strain used to generate this mutant strain.

Development

This strain was generated by crossing 004644 mice with 005557 mice. The resulting mice were intercrossed and maintained as homozygous for the spontaneous allele and homozygous (or hemizygous, as the allele is X-linked) for the targeted mutation allele and hemizygous for the transgenes.
STOCK no. 004644 was developed with the 3 transgenic constructs, Tg(IL3)1Ygy, Tg(CSF2)2Ygy and Tg(KITLG)3Ygy/YgyJ, which were coinjected into NIH/Swiss oocytes. Transgenic founders carrying all 3 transgenes were crossed to FVB and then crossed to NOD.CB17-Prkdc^scid for 7 generations prior to intercrossing.
For STOCK no. 005557, female NOD.CB17-Prkdc^scid/J (Stock No. 001303) mice were crossed with male B6.129S4-Il2rg^tm1Wjl/J mice (Stock No. 003174). The resulting male mice heterozygous for the Prkdcscid allele and hemizygous for the Il2rg^tm1Wjl allele were crossed to female NOD.CB17-Prkdc^scid/J mice for eight generations before being made homozygous (or hemizygous) for both alleles.

Marker name: protein kinase, DNA activated, catalytic polypeptide
Chromosome: 16
Strain of origin: C.BKa-Igh^b/Icr
Site of expression: T and B lymphocytes.
Molecular note: A T-to-A transversion point mutation at a position corresponding to codon 4046 (codon 4095 in transcript ENSMUST00000023352.8) created a premature stop codon (p.Y4046*).

Allele
