To study human T cell differentiation and development, a Hu-SCID mouse model was set up. RAG2-/-/gc-/- double KO mice, which have no T, B and NK cells, are used as immunodeficient mice, in which human fetal hematopoietic stem cells or tissues (from fetal thymus, liver, spleen, bone, cord blood or mobilized peripheral blood cells), are transplanted. Stem cells or precursor cells can be transduced with a gene of interest. Subsequently, the fate of the injected cells can be followed in the HIS-mouse (human immune system mouse) and the role of the gene can be studied.
Since substantial numbers of human cells are present this HIS-mouse can be used to test vaccines and drugs.
