Objective: To test the hypothesis that interleukin- 1ß (IL-ß) and tumor necrosis factor- (TNF- ) regulate granulocyte colony-stimulating factor (G-CSF) production by by human placental villous core mesenchymal cells.
Methods: Villous core mesenchymal cells were isolated from placents at 14-20 weeks' gestation and cultured in vitro. Cells were treated with IL-1ß or TNF- in dose-response and time-course studies. We measured G-CSF mRNA expression by Northem blot analysis and G-CSF protein production by enzyme-linked immunosorbent assay of the conditioned media.
Results: Unstimulated mesenchmal cells expressed negligible G-CSF, Steady-state G-CSF mRNA expression was maximal 3-6 hours after IL-1ß treatment and 6-18 hours after TNF- treatment. Each cytokine induced G-CSF protein production in dose- and time-dependent manners, with IL-1ß more potent than TNF- . The G-CSF mRNA expression and G-CSf production induced by the combination of both cytokines exceeded that induced by either cytokine alone.
Conclusions: Interleukin-1ß and TNF- stimulate G-CSF production by placental villous core mesenchymal cells in vitro. These results identify a potential mechanism by which villous core mesenchymal cells mediate, in part, the response to these two cytokines.
Key Words: Granulocyte colony-stimulating factor interleukin-1ß placenta tumor necrosis factor-
