Peripheral Blood Progenitor Cell Mobilization and Leukapheresis in Pigs
Methods: To obtain large numbers of pig hematopoietic cells, leukapheresis was used to collect blood cell products in miniature swine (n = 5) after progenitor cell mobilization by use of a course of hematopoietic growth factors (cytokines), consisting of porcine interleukin 3, porcine stem cell factor, and human granulocyte colony-stimulating factor.
Results: Cytokine therapy and leukapheresis were well tolerated. Cytokine therapy increased the total white blood cell count and allowed large numbers of leukocytes (60 x 1010) to be obtained by apheresis, of which approximately 0.1% were granulocyte-erythrocyte-monocyte-megakaryocyte colony-forming units (CFUGEMMs), which are considered to be representative of hematopoietic progenitors with multi-lineage potential.
Conclusions: The combination of cytokine therapy and leukapheresis enables hematopoietic progenitor cells to be obtained safely from miniature swine.
