Peripheral Blood - Mononuclear Cell Enriched

Blood that has been enriched for mononuclear white blood cells (Lymphocytes and Monocytes).  This may be accomplished with the use of density gradient separation medium or with a cell processor.  May be referred to as PBMC.

Peripheral Blood Progenitor Cells

Hematopoietic cell with multilineage potential obtained from peripheral blood rather than the bone marrow.  Hematopoietic progenitor cells are induced to circulate following administration of hematopoietic growth factors (e.g. G-CSF, GM-CSF, SCF, IL-3) or following recovery from myeloablation or a combination.  These are normally collected by the process of apheresis and are admixed with other peripheral mononuclear cells.  May also be referred to as peripheral blood stem cells (PBSC).  Proper name is Hematopoietic Progenitor Cells, Apheresis (HPC-A).  This terminology should be used in all relevant laboratory documents.
