Peripheral blood stem cell transplantation (PBSCT), also called "Peripheral stem cell support",[1] is a method of replacing blood-forming stem cells destroyed, for example, by cancer treatment. PBSCT is now a much more common procedure than its bone marrow harvest equivalent, this is in-part due to the ease and less invasive nature of the procedure.[2][3] Studies suggest that PBSCT has a better outcome in terms of the number of hematopoietic stem cell (CD34+ cells) yield.[4]
