Autologous peripheral blood stem cell transplantation is currently used in the treatment of various haematological and non-haematological cancers. Until recently, colony forming unit-granulocyte-macrophage (CFU-GM) assay and mononuclear cell (MNC) count were the indices commonly used to determine the quality of stem cell grafts and the haematopoietic reconstitutive capacity of transplanted stem cells. However, the discovery of CD34 as a stem cell marker has revolutionized the assessment of progenitor cells present in the peripheral blood stem cell graft. Many studies have included enumeration of CD34+ cells, MNCs and CFU-GM assay in stem cell grafts, and their correlation with engraftment has also been studied. However, there is no consensus regarding the optimum dose of each parameter that ensures haematopoietic recovery in all patients. We discuss the stem cell biology and review the literature on stem cell characteristics influencing successful haemopoietic reconstitution.

Multipotency of Hematopoietic Stem Cells

The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Stem Cell Therapy for Tissue Regeneration

Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...
