Published	01/14/2024	Leukocytes (WBCs) are divided into {{c1::mononuclear}} cells and {{c2::granulocytes}}
Published	01/14/2024	{{c1::Macrophages}} differentiate from circulating blood monocytes
Published	01/14/2024	Hematopoiesis occurs via a stepwise maturation of CD-{{c1::34}}+ hematopoietic stem cells
Published	01/14/2024	The CD34+ hematopoietic stem cell may differentiate into a(n) {{c1::myeloid}} or {{c2::lymphoid}} stem cell
Published	01/14/2024	Myeloid stem cells may differentiate into {{c1::erythroblasts}}, which mature into RBCs
Published	01/14/2024	Myeloid stem cells may differentiate into {{c1::myeloblasts}}, which mature into granulocytes
Published	01/14/2024	Myeloid stem cells may differentiate into {{c1::monoblasts}}, which mature into monocytes
Published	01/14/2024	Myeloid stem cells may differentiate into {{c1::megakaryoblasts}}, which mature into megakaryocytes
Published	01/14/2024	Lymphoid stem cells may differentiate into {{c1::B lymphoblasts}}, which mature into naive B cells and then plasma cells
Published	01/14/2024	Lymphoid stem cells may differentiate into {{c1::T lymphoblasts}}, which mature into naive T cells and then CD4+/CD8+ T cells
Published	01/14/2024	A normal WBC count is approximately {{c1::5}} - {{c1::10}} K/μL
Published	01/14/2024	A low WBC count (< 5K) is called {{c1::leukopenia}}
Published	01/14/2024	A high WBC count (> 10K) is called {{c1::leukocytosis}}
Published	01/14/2024	Which immune cell has the cell surface protein CD34? {{c1::Hematopoietic stem cells}}
Published	01/14/2024	The typical normal values for a WBC differential (per USMLE) are:Neutrophils (~ {{c1::60}}%)Lymphocytes (~ {{c1::30}}%)Monocytes (~ {{c1::6}}%)Eosinop…
