Abstract

OP-9 cells are stromal cells derived from macrophage colony-stimulating factor (M-CSF)-deficient osteopetrotic mice. To evaluate the OP-9 capability to sustain long-term hematopoiesis, we reported the expansion of granulocyte colony-stimulating factor (G-CSF)-mobilized human peripheral blood (PB) CD34+ cells in co-culture with murine OP-9 and MS-5 stromal cells, either transfected with various combinations of adenovectors (Ad) expressing c-kit ligand (KL) (either soluble or transmembrane form), thrombopoietin (TPO), flt-3/flk2 ligand (FL), and granulocyte-macrophage (GM)-CSF or with weekly addition of these cytokines. Expression of TPO as well as association of TPO, FL, and KL increased progenitor cell and week-6 cobblestone area forming cell (CAFC) production in all stromal co-cultures. Similar progenitor expansion was obtained by weekly addition of soluble cytokine. Five weeks of co-culture with OP9 and TPO, FL + KL resulted in the greatest expansion of progenitor cells and week-6 CAFC as measured by secondary assay on MS-5. In contrast to MS-5 and TPO or TPO + FL + KL cultures where hematopoiesis declined by week 4, progenitor as well as week-6 CAFC expansion continued for over 3 months in TPO + FL + KL OP9 cocultures. This was associated with decrease of CD14+ macrophage production. The addition of human macrophage (M)-CSF or CD14+ cells to the co-culture decrease progenitor and stem cell expansion; however, murine M-CSF to OP-9 co-cultures did not decrease progenitor expansion. High levels of stromal-derived factor-1 (SDF-1) production by MS-5 and low or absent production by OP-9 may account for stem cell adhesion and CAFC formation in the former cultures and the predominance of stem and progenitor cells in the nonadherent fraction in the latter cultures.
