It begins in the early stages of embryonic In children, haematopoiesis occurs in the marrow of the long bones such as the femur and tibia. In adults, it occurs mainly in the pelvis, cranium, vertebrae, and sternum.

Extramedullary Hematopoiesis . This is the term used for blood cell production that occurs outside of the bone marrow. It can be seen in chronic anemia, with the production of blood cells in the liver, spleen and sometimes in the lymph nodes. In other scenarios, there may be malignant hematopoietic cells located in areas outside of the bone marrow.

These serve as progenitor cells for all the different cell types found in the blood. When hematopoiesis occurs outside the marrow, it is termed extramedullary hematopoiesis. Extramedullary hematopoiesis can occur in many sites, but the most common sites, where we expect to see it under physiologic conditions, is the spleen (red pulp) and liver (portal areas). hematopoiesis [he″mah-to-poi-e´sis] the formation and development of blood cells.

The hematopoietic system, which comprises all the cellular components of the blood, is one of the earliest organ systems to evolve during embryo development. Hematopoietic stem cells (HSCs), which are rare blood cells residing in the bone marrow of the adult organism, are the founder cells that give rise to the entire regulation of hematopoiesis in detail. In humans, fetal hematopoiesis first takes place in the yolk sac and then relocates to the fetal lever. Finally, adult hematopoiesis is translocated to the bone marrow (BM). HSC then resides in the BM and hematopoiesis occurs throughout lifetime in humans (Wasnik et al., 2012).
