Myeloproliferative Neoplasm Animal Models

Myeloproliferative neoplasm (MPN) animal models accurately re-capitulate human disease in mice and have been an important tool for the study of MPN biology and therapy. Transplantation of BCR-ABL transduced bone marrow into irradiated syngeneic mice established the field of MPN animal modeling. Genetically engineered MPN animal models have enabled detailed characterization of the effects of specific MPN-associated genetic abnormalities on hematopoietic stem and progenitor cells (HSPCs). Xenograft models have allowed the study of primary human MPN-propagating cells in vivo. JAK2V617F, the most common molecular abnormality in BCR-ABL negative MPN, has been extensively studied using retroviral, transgenic, knock-in and xenograft models.
