Age-dependent regulation of hematopoiesis by megakaryocytes.
Abstract
Recent studies have expanded the concept of the bone marrow niche beyond stromal cells to include differentiated hematopoietic progeny as direct regulators of hematopoietic stem cells (HSCs). Among these, megakaryocytes have emerged as key niche regulators of HSC function across homeostasis, stress responses, aging, and disease. This review summarizes recent advances defining how aging alters megakaryocyte-mediated regulation of hematopoiesis.

Research summary
This review summarizes how aging alters megakaryocyte-mediated regulation of hematopoiesis, identifying a specific niche mechanism involved in age-related hematopoietic decline. The paper is relevant because it addresses a root cause of hematopoietic aging, but as a review summarizing existing knowledge rather than presenting new experimental data or proposing a novel therapeutic intervention, its direct impact on lifespan extension is limited.
