Human Mobilized Peripheral Blood Leukopaks® are collected from healthy IRB consented donors that are injected with Granulocyte-Colony Stimulating Factor (G-CSF aka Neupogen®), Plerixafor (aka Mozobil®), or a combination of Plerixafor and G-CSF, which increases circulating leukocytes and stimulates the bone marrow to produce a large number of hematopoietic and progenitor stem cells and mobilizes these cells into the bloodstream, allowing for enriched CD34+ hematopoietic stem cells from a single donor as compared to traditional Leukopaks®. Collecting CD34+ stem cells from a single donor eliminates donor-to-donor variation, allows scalability of stem cell studies, and decreases same cell variability. Mobilized Leukopaks® are ideal for stem cell studies relating to regenerative medicine, immunotherapy, and transplant therapy.

StemExpress offers PBMCs and CD34+ stem cells mobilized with G-CSF, Plerixafor, and G-CSF plus plerixafor. The mechanism of action of these mobilization agents, and the combination of them, have been shown to change the expression profile, cell composition, and engraftment potential of the mobilized cells.1,2,3 Therefore, it is important to understand that switching mobilization reagents during a study may also change the mobilized cell type and their effect on studies relating to transplantation and stem cell research.
