Hu-CD34+ NSG-SGM3 are NSG-SGM3 (NOD.Cg-Prkdcscid Il2rgtm1Wjl Tg(CMV-IL3, CSF2, KITLG)1Eav/MloySzJ, Stock No. 013062) mice engrafted with human cord blood-derived CD34+ hematopoietic stem cells. NSG-SGM3 mice combine the features of the highly immunodeficient NOD scid gamma (NSG) mouse platform with transgenic expression of human IL3, GM-CSF (CSF2) and SCF (KITLG) cytokines for improved development of human myeloid lineages and regulatory T cell populations. hu-CD34+ NSG-SGM3 mice exhibit superior, stable engraftment of diverse hematopoietic lineages for immunology and immuno-oncology research.

Similar to other immunodeficient strains, maintaining NSG-SGM3 mice in high health status (specific pathogen-free) vivaria promotes overall colony health. The fertility of hu-CD34+ NSG-SGM3 mice has not been tested. The engrafted human immune system is not heritable and would not be transmitted by breeding. A small percentage of hu-CD34+ NSG-SGM3 may develop macrophage activation syndrome (MAS). Please see our FAQ below for more details.
