Hematopoiesis & Cells
This pluripotent cell, found in the bone marrow, is the common progenitor of all red blood cells, white blood cells, and platelets.
What is the hematopoietic stem cell?
This ancient medical concept is defined by the four Latin symptoms: calor (heat), dolor (pain), rubor (redness), and tumor (swelling).
What is inflammation?
These are the most abundant white blood cells; they are short-lived "infantry" that capture and kill microorganisms, often dying to form pus.
What are neutrophils?
These star-shaped tissue residents determine when innate immunity needs reinforcement by carrying pathogen cargo to lymphoid tissues to initiate an adaptive response
What are dendritic cells?
These large "commander" cells detect infection, phagocytose pathogens, and secrete cytokines to recruit other leukocytes.
What are macrophages?
These giant cells reside permanently in the bone marrow and produce platelets by releasing membrane-bound packets of cytoplasm.
What are megakaryocytes?
