Two murine myelofibrosis models driven by excessive JAK2 activity (nude mice bearing Ba/F3-JAK2 cells)
“Two proof-of-concept studies were conducted in murine models of myelofibrosis whose pathology is driven by excessive JAK2 activity, recapitulating the dysregulated JAK/STAT pathway described in human myelofibrosis.”
