![]() ![]() Donnell Thomas, continued his research on the development of bone marrow transplantation and later received the Nobel Prize for Physiology and Medicine for his work. ![]() These animal-based studies soon found their clinical application in humans when the first successful bone marrow transplant was performed between monozygotic twins in New York in 1957 to treat acute leukemia. It was based on observational studies in mice models, which showed that infusion of healthy bone marrow components into a myelosuppressed bone marrow could induce recovery of its function in the recipient. Hematopoietic stem cell transplantation (HPSCT) was first explored for use in humans in the 1950s. It can also generate functional cells that replace dysfunctional ones in cases like immune deficiency syndromes, hemoglobinopathies, and other diseases. In addition, depending on the disease being treated, it may allow for the destruction of malignant tumor cells. It helps to augment bone marrow function. In a child, the decision whether to use cells from the bone marrow or the blood depends on the size of the child.Hematopoietic stem cell transplant (HPSCT), sometimes referred to as bone marrow transplant, involves administering healthy hematopoietic stem cells to patients with dysfunctional or depleted bone marrow. In adults, most autologous transplants use stem cells from blood. This way of collecting stem cells is called apheresis. The machine then returns the remaining blood through a needle in your arm or through a central venous catheter. ![]() Your blood is removed from a vein and passed through a machine that separates the stem cells. G-CSF is a protein that is produced naturally in the body. The growth factor G-CSF may be used to stimulate the growth of new stem cells so they spill over into the blood. With PBSCT, the stem cells are taken from your blood. Waiting for the transplanted stem cells to produce healthy blood cells.Īutologous stem cell transplants are done using peripheral blood stem cell transplantation (PBSCT).This destroys cancer cells or damaged stem cells. Having chemotherapy (sometimes along with radiation).The cells are stored until you need them for transplant. Your blood is sent through a machine that separates stem cells from your blood. The autologous transplant process includes: So the stem cells may be treated to get rid of any cancer cells before being put back into your body. But stem cells from your own marrow or blood may still contain some cancer cells. That's because your body won't reject your own stem cells. Using your own stem cells in a transplant is safer than using someone else's. In a child, the decision whether to use cells from the bone marrow or the blood depends on the child's size. A stem cell transplant may be used to replace damaged stem cells with new, normal stem cells.Ī stem cell transplant may be needed to treat diseases, such as non-Hodgkin lymphoma and Hodgkin lymphoma, leukemia, multiple myeloma, and aplastic anemia. If your bone marrow is attacked by a disease such as multiple myeloma, it can no longer make normal blood cells. Bone marrow stem cells turn into red blood cells, white blood cells, or platelets to help your body stay healthy. You also have some in your blood that circulate from your bone marrow. When they come from you, it's called an autologous stem cell transplant. Or the stem cells can come from another person. A stem cell transplant can use stem cells that come from your own blood or bone marrow. ![]()
