Basic Information
Description
Immunodeficient B-NDG mice were generated by deleting the IL2rg gene from NOD-scid mice. This mouse model has the highest degree of immunodeficiency and is most suitable for engraftment and growth of human tumor cells or tissues.

B-NDG hTHPO mice are well suited for human immune system engraftment
Human CD34+ cells(0.15M) were intravenous implanted into homozygote B-NDG hTHPO and B-NDG mice (female, 6 week-old, n=20). B-NDG mice were treated with 2gry-irradiation, B-NDG hTHPO mice were not irradiated. Representative flow cytometric analysis of PBMCs from mice after engraftment with human CD34+ cells. B-NDG hTHPO mice show a higher percentage of survival rate compared with B-NDG.Non-irradiated B-NDG hTHPO mice showed no difference in the percentage of human CD45+ cells compared to B-NDG mice. The results showed that the human HSC (hematopoietic stem cells) engrafted humanized mice model was successfully constructed.

Non-irradiated B-NDG hTHPO mice showed no difference in the percentage of human multi-lineage cells compared to B-NDG mice, including T ,B, NK, myeloid cells,monocyte and neutrophils. The results showed that the human HSC (hematopoietic stem cells) engrafted humanized mice model was successfully constructed.
