claimB lymphocytes are named for being bone marrow derived, and T lymphocytes are named for being thymus derived.
claimNaive lymphocytes are small B and T lymphocytes that have matured in the bone marrow and thymus but have not yet encountered an antigen.
claimThe central lymphoid organs are the bone marrow and the thymus.
claimImmune responses are mediated by leukocytes, which derive from precursors in the bone marrow.
claimAll cellular elements of blood, including red blood cells, platelets, and white blood cells, derive from hematopoietic stem cells located in the bone marrow.
claimB lymphocytes mature in the bone marrow, while T lymphocytes mature in the thymus.
claimThe bone marrow and the thymus are classified as central or primary lymphoid organs.
claimB lymphocytes and T lymphocytes both originate in the bone marrow, but B lymphocytes mature in the bone marrow while T lymphocytes migrate to the thymus to undergo maturation.
claimWhite blood cells of the immune system derive from precursors in the bone marrow.
claimImmune system cells originate in the bone marrow, where many of them also mature, before migrating to guard peripheral tissues via the blood and the lymphatic system.

claimMature T cells leave the thymus as naïve T cells and populate organs such as the spleen, lymph nodes, bone marrow, and blood, where they may become memory T cells after antigen exposure.
claimT cells develop from hematopoietic stem cells in the bone marrow and complete their development in the thymus, a specialized organ in the chest.
claimB cells develop from stem cells in the bone marrow, where they undergo maturation and training to ensure they do not produce antibodies against healthy tissues.
claimMature B cells are located in the bone marrow, lymph nodes, spleen, some areas of the intestine, and the bloodstream.
claimNeutrophils develop from hematopoietic stem cells in the bone marrow.
Pro-Inflammatory Cytokines Overview | Thermo Fisher Scientific - US thermofisher.com 2 facts
referenceG-CSF is classified as a pro-inflammatory cytokine, is produced by fibroblasts and endothelium, binds to the CD114 receptor, targets stem cells in the bone marrow, and functions in granulocyte production.
referenceIL-1 is classified as a pro-inflammatory cytokine, is produced by macrophages, B cells, and dendritic cells, binds to the CD121a receptor, targets B cells, NK cells, and T cells, and functions in pyrogenic activity, inflammation, cell proliferation, differentiation, and bone marrow cell proliferation.

claimT cells travel from the bone marrow to the thymus via the bloodstream to mature.
procedureDendritic cells are produced in bone marrow, migrate through the blood to tissues to monitor for pathogens, and upon encountering a pathogen, phagocytose it and present pieces of it as antigens on their surface.
