Hematopoietic Stem Cell Transplantation (HSCT) is the intravenous infusion of hematopoietic stem and progenitor cells to bone marrow and immunological function in individuals with a range of acquired and hereditary malignant and nonmalignant illnesses. In patients with damaged or dysfunctional bone marrow or immune systems, HSCT includes the intravenous injection of hematopoietic stem cells to reestablish blood cell production. During the last halfcentury, this method has been increasingly used to treat a range of malignant and nonmalignant illnesses. The patient's own cells (autologous transplant), a sibling or unrelated donor's cells (allogeneic transplant), or an identical twin's cells (allogeneic transplant) can all be used for HSCT (syngeneic transplant). Cells can also come from bone marrow, peripheral blood, umbilical cord blood, and, in rare circumstances, foetal liver.

Bone marrow, peripheral blood, and umbilical cord blood are all places where cells can be found. Hematopoietic Stem Cell Transplantation (HSCT) has become the gold standard of treatment for many patients with known congenital or acquired hematopoietic system defects, chemo radiotherapy, or immuno-sensitive malignancies. HSCT has had fast growth and steady technological improvement during the previous two decades. New indicators are constantly being tested. Peripheral blood or cord blood is used to complement bone marrow as a stem cell source. More than 14 million typed volunteer donors or cord blood units from various registries throughout the globe supply stem cells for patients who do not have a family donor. New low intensity training regimens have made HSCT more accessible to elderly individuals and those with co-morbidities.

Hematopoietic stem cell transplants, which include peripheral blood, bone marrow, and cord blood, are most commonly utilized to treat malignancies of the blood and immune system. Autologous and allogeneic stem cell transplants are the two most common forms. Autologous stem cells are derived from the patient receiving the transplant and are used to treat leukemia’s, lymphomas, and multiple myeloma, as well as other malignancies including testicular cancer and neuroblastoma. Certain children malignancies are also treated with autologous stem cell transplantation. The reinfused stem cells are taken from the patient's own bone marrow and retrieved from the peripheral blood, which is a benefit of autologous transplantation. Because these cells do not induce Graft Versus Host Disease (GVHD), autologous transplantation has a lower risk of morbidity and death than allogeneic BMT, extending the age range and number of patients who can benefit from the operation.

Stem cell transplantation progenitor cells are derived from a different person. They can come from a related or unrelated donor, as well as a donor who isn't a perfect match. Leukemia’s, lymphomas, and non-malignant hereditary diseases are the most prevalent uses for allogenic stem cells. The donor stem cells produce their own immune cells, which may aid in the killing of any cancer cells that survive high-dose therapy. This phenomenon is known as the graftversus- cancer or graft versus tumor effect. The transplant has the benefit of graft vs. cancer, but it also comes with the risk of graft vs. host illness. This method is made more difficult by the requirement to balance these two results. Other benefits include the ability to request more stem cells or even white blood cells from the donor if necessary, and the fact that stem cells from healthy donors are cancer free.
