Emergency myelopoiesis raises neutrophil supply during infection or inflammatory demand
Bone marrow survival niches maintain long-lived plasma cells and durable antibody output
Bone remodeling and marrow niches are coupled through osteoblast, osteoclast, stromal, and hematopoietic signaling

Immune niche
Tissue Ecology
Bone marrow is the immune system's production and memory-support organ. Stromal niches, cytokines, sympathetic tone, iron metabolism, and inflammatory demand determine leukocyte output, antibody durability, and emergency myelopoiesis.
