pubmed:abstractText |
Interleukin-6 (IL-6, also known as B-cell stimulatory factor 2/interferon beta 2) was previously shown to support the proliferation of granulocyte/macrophage progenitors and indirectly support the formation of multilineage and blast cell colonies in cultures of spleen cells from normal mice. We report here that IL-3 and IL-6 act synergistically in support of the proliferation of murine multipotential progenitors in culture. The time course of total colony formation by spleen cells isolated from mice 4 days after injection of 5-fluorouracil (150 mg/kg) was significantly shortened in cultures containing both lymphokines relative to cultures supported by either of the two factors. Serial observations (mapping) of individual blast cell colonies in culture revealed that blast cell colonies emerged after random time intervals in the presence of IL-3. The average time of appearance in IL-6 alone was somewhat delayed, and in cultures containing both factors the appearance of multilineage blast cell colonies was significantly hastened relative to cultures grown in the presence of the individual lymphokines. In cultures of day-2 post-5-fluorouracil bone marrow cells, IL-6 failed to support colony formation; IL-3 alone supported the formation of a few granulocyte/macrophage colonies, but the combination of factors acted synergistically to yield multilineage and a variety of other types of colonies. In this system, IL-1 alpha also acted synergistically with IL-3, but the effect was smaller, and no multilineage colonies were seen. Together these results indicate that IL-3 and IL-6 act synergistically to support the proliferation of hemopoietic progenitors and that at least part of the effect results from a decrease in the G0 period of the individual stem cells.
