Erythropoiesis-stimulating agents (ESA) are medications which stimulate the bone marrow to make red blood cells. [1] They are used to treat anemia due to end stage kidney disease, chemotherapy, major surgery, or certain treatments in HIV/AIDS. [1] [2] In these situations they decrease the need for blood transfusions. [2]
Granulocyte colony-stimulating factor (G-CSF or GCSF), also known as colony-stimulating factor 3 (CSF 3), is a glycoprotein that stimulates the bone marrow to produce granulocytes and stem cells and release them into the bloodstream.
In 1939, a woman with aplastic anaemia received the first human bone marrow transfusion. This patient received regular blood transfusions, and an attempt was made to increase her leukocyte and platelet counts by intravenous bone marrow injection without unexpected reaction. [72]

As ADSCs adhere to bone marrow endothelium, MSCs express several different molecules that increase the adhesion such as CD44 isoforms and integrins. As ADSCs transmigrate through vessels in bone marrow, interaction and signaling between stromal-derived chemokine factor -1 and receptor CXCR4 is the most crucial process. [9] [10]
These could be fat stem cells or mesenchymal stem cells (harvested from bone marrow cells, fat tissue or dental pulp). Or they may come from elsewhere. In any case, they’re typically harvested ...
