White blood cells, red blood cells, and platelets are all forms of blood cells that can originate from an immature cell. Hematopoietic stem cells can be detected in the bone marrow and peripheral blood. Also known as a blood stem cell. To manufacture and replenish the blood system, hematopoiesis — the synthesis of blood cells components – occurs during embryonic development and throughout maturity. Hematopoiesis research can assist scientists and doctors better understand the processes that lead to blood diseases and tumours. Hematopoietic stem cells (HSCs) can also be utilised as a model system to study tissue stem cells and their function in ageing and cancer. By contrast, definitive hematopoiesis occurs later in development, and at different times in different species.
The production of lymphocytes, one of the five types of white blood cells, is known as lymphopoiesis (WBC). Lymphoid hematopoiesis is the more formal name for it. Lymphomas and lymphoid leukemias are examples of lymphoproliferative illnesses caused by disruption in lymphopoiesis. Lymphocytes belong to the lymphoid lineage, which differs from the myeloid and erythroid lineages of blood cells.
