Abstract The effects of FLT3/FLK-2 ligand (FL) and KIT ligand (KL) on in vitro expansion of hematopoietic stem cells were studied using lineage-negative (Lin−)Sca-1–positive (Sca-1+) c-kit–positive (c-kit+) marrow cells from 5-fluorouracil (5-FU)–treated mice. As single agents, neither FL nor KL could effectively support the proliferation of enriched cells in suspension culture. However, in combination with interleukin-11 (IL-11), both FL and KL enhanced the production of nucleated cells and progenitors. The kinetics of stimulation by FL was different from that by KL in that the maximal expansion by FL of the nucleated cell and progenitor pools required a longer incubation than with KL. We then tested the reconstituting abilities of cells cultured for 1, 2, and 3 weeks by transplanting the expanded Ly5.1 cells together with “compromised” marrow cells into lethally irradiated Ly5.2 mice. Cells that had been expanded with either cytokine combination were able to maintain the reconstituting ability of the original cells. Only cells that had been incubated with KL and IL-11 for 21 days had less reconstituting ability than fresh marrow cells. These results indicate that there can be significant expansion of progenitors in vitro without compromising the reconstituting ability of stem cells. Addition of IL-3 to permissive cytokine combinations significantly reduced the ability of cultured cells to reconstitute the hematopoiesis of irradiated hosts. These observations should provide a basis for a rational approach to designing cytokine combinations for in vitro expansion of hematopoietic stem cells.
