Blood derived from a patient's blood stream, as opposed to blood in the bone marrow where it is made. Blood stem cell production is stimulated in the donor by administration of the drug Filgrastim and then harvested painlessly from the donor through a medical procedure called apheresis.
Peripheral blood flows through the bloodstream of the body. Some blood stem cells are found in the peripheral blood.
Also called hematopoietic stem cells, they are the immature cells from which all blood cells develop.
Stem cells that circulate in the blood.
Cells with the potential to produce all the components of blood. Peripheral Blood Stem Cells (PBSC) are obtained from "circulating" blood rather than from bone marrow.
