Robust humanized mouse models are critical for studying human hematopoietic stem cell (HSC) engraftment and immune system reconstitution. GemPharmatech developed a novel triple-engineered NCG-mTslp-hIL6-mFlt3 KO mouse model by introducing human IL-6, expressing mouse TSLP, and knocking out mouse Flt3 to optimize human immune development. Following human CD34+ HSC transplantation, the model exhibited significantly enhanced reconstitution of T cells, B cells, NK cells, and dendritic cell subsets, accompanied by improved lymphoid tissue development. Administration of human FLT3L further boosted immune cell expansion. This advanced model provides a superior platform for immunology research and preclinical evaluation of immune-based therapies.
