Description

These NOD.scid porcine IL-3-CSF2-KITLG mice express a transgene encoding porcine interleukin 3 (IL3), porcine granulocyte macrophage-colony stimulating factor (CSF2), and soluble porcine stem cell factor (KITLG), and produce porcine IL-3, CSF2 and KITLG in bone marrow and spleen.

Detailed description

Tg(IL3)1Ygy, Tg(CSF2)2Ygy, and Tg(KITLG)3Ygy encode porcine interleukin 3 (IL3), Porcine granulocyte macrophage-colony stimulating factor (CSF2, commonly designated GM-CSF) and soluble Porcine stem cell factor (KITLG, commonly designated sSCF) respectively. All three are individually driven by the human cytomegalovirus promoter. These three transgenes were co-injected and they co-segregate. RT-PCR detects transgenic expression of porcine IL-3, CSF2 and KITLG in bone marrow and spleen in NOD.Cg Prkdc ^scid-Tg(IL3)1Ygy Tg(CSF2)2Ygy Tg(KITLG)3Ygy mice. Porcine IL3, CSF2, and KITLG are present in the serum of these mice in levels that can be detected by ELISA. NOD.Cg Prkdc ^scid-Tg(IL3)1Ygy Tg(CSF2)2Ygy Tg(KITLG)3Ygy/YgyJ not only provide a system in which long-term porcine tissue and stem cell engraftment can be achieved (Abe et al, 2002) but also is a useful tool for evaluating donor-specific tolerance induction by mixed chimerism across xenogeneic barriers (Chen et al, 2000). White blood cells of NOD.Cg Prkdc^scid-Tg(IL3)1Ygy Tg(CSF2)2Ygy Tg(KITLG)3Ygy mice are CD4^-, CD8^-, CD3^-, IgM^-, CD19^- and Mac-1⁺ by flow cytometric (FMC) analysis. White blood cells of Tg(IL3)1Ygy Tg(CSF2)2Ygy Tg(KITLG)3Ygy mice sub-lethally irradiated, i.v. injected with miniature swine bone marrow cells and i.p. injected with peripheral blood mononuclear cells (PBMC) are swine myeloid CD-2⁺, class II⁺ and CD16⁺ 20 weeks post bone marrow transplant by FMC. Non-transgenic littermates had low levels of chimerism detected at 3 weeks and non-existent at 7 weeks post bone marrow transplant (BMT). At 20 weeks post BMT these transgenic mice revealed high levels of chimerism in the spleen and bone marrow cells, versus no chimerism in any tissue of non-transgenic littermates. Treated transgenic mice showed peak levels of porcine T cell chimerism at 7 weeks post transplantation. Neither B nor T cells were detectable at 20 weeks post transplantation (Chen et al, 2000).
