Beyond compensation: Organized pathological hematopoiesis in the myelofibrotic spleen.

Organized pathological hematopoiesis occurs in the myelofibrotic spleen, involving complex cellular and stromal remodeling, challenging the idea of simple compensation.

• Why it matters: Understanding how hematopoiesis is reorganized in disease states like myelofibrosis is crucial for developing targeted therapies, as the spleen becomes a key site of abnormal blood cell production.
• What they did: Two studies analyzed the spleen in myelofibrosis, with Austin et al. characterizing cellular states and Dugué et al. mapping the spatial and temporal changes in the stromal niche.
• The result: Findings reveal a structured, remodeled hematopoietic environment in the spleen, providing insights into disease progression and potential intervention points for myelofibrosis.
