Philadelphia-Negative MPN: A Molecular Journey, from Hematopoietic Stem Cell to Clinical Features

Area of Science:

• Hematology
• Oncology
• Stem Cell Biology

Background:

• Philadelphia-negative Myeloproliferative Neoplasms (MPN) are a diverse group of hematopoietic stem cell disorders.
• MPNs are associated with varying risks of thrombotic events and progression to acute myeloid leukemia.
• Recent advancements in molecular diagnostics, including JAK2 mutation detection and next-generation sequencing, have deepened our understanding of MPNs.

Purpose of the Study:
