Lineages
Blood cells are divided into three lineages: Erythroid, Lymphoid, Myeloid. Granulopoiesis is hematopoiesis of granulocytes.
All blood cells are divided into three lineages.
- Erythroid cells are the oxygen carrying red blood cells.
- Lymphoid cells are the cornerstone of the adaptive immune system. They are derived from common lymphoid progenitors. The lymphoid lineage is primarily composed of T-cells and B-cells. (white blood cells)
- Myeloid cells, which includes granulocytes, megakaryocytes, and macrophages, are derived from common myeloid progenitors, and are involved in such diverse roles as innate immunity, adaptive immunity, and blood clotting.
