Bone marrow adipose tissue (BMAT), sometimes referred to as marrow adipose tissue (MAT), is a type of fat deposit in bone marrow.It increases in states of low bone density, such as osteoporosis, [1] [2] anorexia nervosa/caloric restriction, [3] [4] skeletal unweighting such as that which occurs in space travel, [5] [6] and anti-diabetes therapies.

The most commonly used source of MSC's is bone marrow aspirate. Most of the adult bone marrow consists of blood cells in various stages of differentiation. [10] These marrow components can be divided into plasma, red blood cells, platelets, and nucleated cells. The adult stem cell fraction is present in the nucleated cells of the marrow.
Anti-thymocyte globulin (ATG) is an infusion of horse or rabbit-derived antibodies against human T cells and their precursors , which is used in the prevention and treatment of acute rejection in organ transplantation and therapy of aplastic anemia due to bone marrow insufficiency.
Hematopoietic stem cell transplantation (HSCT) is the transplantation of blood stem cells derived from the bone marrow (that is, bone marrow transplantation) or blood. Stem cell transplantation is a medical procedure in the fields of hematology and oncology , most often performed for people with diseases of the blood , bone marrow , or certain ...
A bone marrow harvest in progress The preferred sites for the procedure. In a bone marrow transplant, hematopoietic stem cells are removed from a person and infused into another person or into the same person at a later time . If the donor and recipient are compatible, these infused cells will then travel to the bone marrow and initiate blood ...
A classical event is the retroposition of a spliced pre-mRNA molecule of the c-Src gene into the proviral ancestor of the Rous sarcoma virus (RSV). The retroposed c-src pre-mRNA still contained a single intron and within RSV is now referred to as v-Src gene.
Hematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. [16] [17] [13] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an identical twin).
The four main types of tissue transplantation are xenotransplantation, allotransplantation, isotransplantation and autotransplantation, while the common tissues transplanted include skin, bone, corneal and vessel grafts. [3] Tissue transplantation comes with risks and complications, including immune rejection and viral infections.
