Hematopoietic precursor cells: promyelocyte in the center, two metamyelocytes next to it and band cells from a bone marrow aspirate. At the cellular level, the main functional component of bone marrow includes the progenitor cells which are destined to mature into blood and lymphoid cells.
How are stem cells used in bone marrow transplants?
In a bone marrow transplant, hematopo ietic stem cells are removed from a person and infused into another person ( allogenic) or into the same person at a later time ( autologous ). If the donor and recipient are compatible, these infused cells will then travel to the bone marrow and initiate blood cell production. Transplantation from one person to another is conducted for the treatment of severe bone marrow diseases, such as congenital defects, autoimmune diseases or malignancies. The patient's own marrow is first killed off with drugs or radiation, and then the new stem cells are introduced. Before radiation therapy or chemotherapy in cases of cancer, some of the patient's hematopoietic stem cells are sometimes harvested and later infused back when the therapy is finished to restore the immune system.

Why is bone marrow important?
Bones are the entire skeletal system of the body that is constantly providing us support and the marrow has an important role in the circulation of blood and the blood health along with our immune system. Especially after the age of 30, the strength of the bone starts to weaken and if proper care is not taken then with weakening bones the bone marrow also fails to function properly and support the body. One must take care and stay healthy and bone health is as important as any other part of the body.

What is the cytochemistry of acute leukemia?
Cytochemistry. To distinguish between reactive processes and chronic myeloid leukemia, leukocyte alkaline phosphatase is determined in fresh smears of blood. To distinguish between different types of acute leukemia, the peroxidase and esterase reactions are carried out (pp. 97 and 99), and iron staining is performed (p. 109) if myelodysplasia is suspected.
Is lymphocyte count a quantitative or qualitative assessment?
Qualitative and Quantitative Assessment of the Remaining Cells. Lymphocyte counts may be slightly raised in reactive processes, but a significant increase suggests a disease of the lymphatic system. The exact classification of these disease follows the criteria of lymphocyte morphology (Fig. 16). If elevated lymphocyte counts are found only in one preparation or within a circumscribed area, physiological lymph follicles in the bone marrow are likely to be the source. In a borderline case, the histology and analysis of lymphocyte surface markers yield more definitive data.

What is the condition where bone marrow doesn't produce enough blood cells?
Aplastic anemia. Aplastic anemia occurs when bone marrow doesn’t produce enough new blood cells. It occurs from damage to the stem cells of bone marrow. This makes it harder from them to grow and develop into new blood cells.
How do white blood cells work?
There are several types of white blood cells. They all work to help your body fight off infections. Newly produced blood cells enter your bloodstream through vessels called sinusoids. As you age, your red bone marrow is gradually replaced with yellow bone marrow.

What is the function of yellow bone marrow?
Yellow bone marrow is involved in the storage of fats. The fats in yellow bone marrow are stored in cells called adipocytes. This fat can be used as an energy source as needed. Yellow bone marrow also contains mesenchymal stem cells. These are cells that can develop into bone, fat, cartilage, or muscle cells.
Where are stem cells found?
Hematopoietic stem cells that are found in red bone marrow can develop into a variety of different blood cells, including: Red blood cells.

Overview
Structure
The composition of marrow is dynamic, as the mixture of cellular and non-cellular components (connective tissue) shifts with age and in response to systemic factors. In humans, marrow is colloquially characterized as "red" or "yellow" marrow (Latin: medulla ossium rubra, Latin: medulla ossium flava, respectively) depending on the prevalence of hematopoietic cells vs fat cells. While the precise mechanisms underlying marrow regulation are not understood, compositional chang…

The normal bone marrow architecture can be damaged or displaced by aplastic anemia, malignancies such as multiple myeloma, or infections such as tuberculosis, leading to a decrease in the production of blood cells and blood platelets. The bone marrow can also be affected by various forms of leukemia, which attacks its hematologic progenitor cells. Furthermore, exposure to radiat…
Fossil record
The earliest fossilised evidence of bone marrow was discovered in 2014 in Eusthenopteron, a lobe-finned fish which lived during the Devonian period approximately 370 million years ago. Scientists from Uppsala University and the European Synchrotron Radiation Facility used X-ray synchrotron microtomography to study the fossilised interior of the skeleton's humerus, finding organised tubular structures akin to modern vertebrate bone marrow. Eusthenopteron is closely related to t…
