This abstract first appeared for US patent application 18744415 titled 'VECTORS, GENETICALLY MODIFIED CELLS, AND GENETICALLY MODIFIED NON-HUMAN ANIMALS COMPRISING THE SAME
Original Abstract Submitted
Provided herein are genetically modified cells and genetically modified non-human animals (e.g., rodents such as rats and mice) comprising: (i) a homozygous null mutation in Rag2 gene; (ii) a homozygous null mutation in IL2rg gene; (iii) a homozygous null mutation in the non-human animal FMS-like tyrosine kinase 3 (Flt3) gene, and (iv) a Flt3 ligand (Flt31) gene that comprises a non-human animal portion and a human portion operably linked to a Flt31 promoter, and optionally expressing one or more human or humanized polypeptides. Methods and compositions of making and using such genetically modified cells and non-human animals are also provided.
