- In addition, the bone marrow contains hematopoietic stem cells, which give rise to the three classes of blood cells that are found in the circulation: white blood cells (leukocytes), red blood cells (erythrocytes), and platelets (thrombocytes).n humans, red blood cells are produced by cores of bone marrow in the heads of long bones in a process known as hematopoiesis. On average, bone marrow constitutes 4% of the total body mass of humans; in an adult weighing 65 kilograms (143 lb), bone marrow typically accounts for approximately 2.6 kilograms (5.7 lb).

Human Tissue Sample Blog 2009. Bone marrow (also known as myeloid tissue) is a red, soft, semi-solid, gelatinous tissue, which is found in the axial skeleton. It is highly vascular and enriched with many blood vessels and capillaries. Deep within the bone marrow resides a type of cell known as mesenchymal stem cells (MSCs).

Aplastic anemia Aplastic anemia is a rare disease in which the bone marrow and the hematopoietic stem cells that reside there are damaged. This causes a deficiency of all three blood cell types (pancytopenia): red blood cells (anemia), white blood cells (leukopenia), and platelets (thrombocytopenia). Aplastic refers to inability of the stem cells to generate mature blood cells. It is most prevalent in people in their teens and twenties, but is also common among the elderly. It can be caused by exposure to chemicals, drugs, radiation, immune disease, and heredity. However, in about half the cases, the cause is unknown. The definitive diagnosis is by bone marrow biopsy; normal bone marrow has 30–70% blood stem cells, but in aplastic anemia, these cells are mostly gone and replaced by fat.

Aplastic Anemia Aplastic anemia is the medical term for bone marrow failure. We treat patients with aplastic anemia at our Bone Marrow Failures Disorders Program at the Johns Hopkins Kimmel Cancer Center. The bone marrow, a spongy tissue inside the bones, is the factory for all blood cell lines -- red cells, white cells, and platelets.

Overview of blood and blood components The production and development of new cells in the bone marrow is a process called hematopoiesis. Blood cells formed in the bone marrow start out as a stem cell. A stem cell (or hematopoietic stem cell) is the initial phase of all blood cells.As the stem cell matures, several distinct cells evolve, such as the red blood cells, white blood cells, and platelets. Immature blood cells are also called blasts.he production and development of new cells in the bone marrow is a process called hematopoiesis.

Hematopoiesis Overview. 1  Hematopoiesis refers to the process that generates new, mature blood cells. 2  All such cells ultimately derive from a single progenitor cell termed the Hematopoietic Stem Cell (HSC) which undergoes a process of highly regulated division and differentiation that produces the gamut of mature blood cells.

Bone Marrow and Blood Cell Development Bone marrow is the soft, flexible connective tissue within bone cavities. A component of the lymphatic system, bone marrow functions primarily to produce blood cells and to store fat.Bone marrow is highly vascular, meaning that it is richly supplied with a large number of blood vessels. There are two categories of bone marrow tissue: red marrow and yellow marrow. Red marrow contains hematopoietic stem cells that produce two other types of stem cells: myeloid stem cells and lymphoid stem cells. 2  These cells develop into red blood cells, white blood cells, or platelets.

Hematopoietic Stem Cells Hematopoietic Stem Cells. Hematopoietic progenitor cells (HPCs) or hematopoietic stem cells (HSCs) are cells present in blood and bone marrow. HPCs are capable of forming mature blood cells, such as red blood cells (the cells that carry oxygen), platelets (the cells that help stop bleeding) and white blood cells (the cells that fight infections). Click here to see differentiation pathways. HPCs are used in the treatment of many malignant (e.g., leukemia, lymphoma) and non-malignant (e.g., sickle cell disease) diseases to replace or rebuild a patient's hematopoietic system. This type of treatment is called a bone marrow or stem cell transplant.

- Hematopoietic stem cell transplants are now routinely used to treat patients with cancers and other disorders of the blood and immune systems. Recently, researchers have observed in animal studies that hematopoietic stem cells appear to be able to form other kinds of cells, such as muscle, blood vessels, and bone.he gold standard for proving that a cell derived from mouse bone marrow is indeed an HSC is still based on the same proof described above and used in mice many years ago. That is, the cells are injected into a mouse that has received a dose of irradiation sufficient to kill its own blood-producing cells.

What is Hematopoiesis? During fetal development, hematopoiesis occurs in the liver, spleen and bone marrow. After birth and through development, the bone marrow takes over as the main site of blood cell formation, and by adulthood, the process is mostly streamlined to several main sites.rythrocytes are red blood cells that carry oxygen to different areas of the body. Hematopoiesis creates new blood cells. Hematopoiesis takes place in the liver, bone marrow and spleen during fetal development.
