Research summary

This study explores the development of a humanized rat model by engrafting human CD34+ hematopoietic stem cells (HSCs) into immunodeficient rats. The research aims to establish a robust platform for studying human immune responses and diseases within a rat model, which offers advantages over existing mouse models due to its larger size and physiological similarities to humans.

Key outcome of the study

The humanized rat model demonstrated successful engraftment of human CD34+ cells, leading to the development of functional human immune cells. This model provides a valuable tool for preclinical research, including the evaluation of immunotherapies and the study of human-specific pathogens.

Mouse model

The study utilized an immunodeficient rat model developed in collaboration with genOway. These rats were genetically engineered to lack functional T, B, and NK cells, creating a permissive environment for the engraftment and development of a human immune system. The model allows for the differentiation and maturation of human immune cells, enabling the study of human-specific immune functions and disease processes.
