Abstract We have examined the expression of the intercellular adhesion molecule- 1 (ICAM-1) mRNA in primary and established amnion-derived cell cultures and regulation of this expression by tumour necrosis factor-α (TNF-α) and interleukin (IL)-1β. TNF-α (50 ng/ml) and IL-1β (1.0 ng/ml) induced 18- and 11-fold increases respectively in expression of the ICAM-1 mRNA in WISH cells (an amnion epithelium-derived cell line). The increase was detectable within one hour of treatment and peaked by two hours. The protein synthesis inhibitor, cycloheximide (10 μg/ml) did not inhibit this induction. Increased levels of ICAM-1 protein were detected in the cells within 4 h after initiation of treatment with either cytokine. By 16 h of treatment with IL-1β or TNF-α ICAM-1 reached 40 and 73pg/μg cellular protein, representing 6- and 11-fold stimulations respectively. In primary amnion cells, basal expression of ICAM-1 mRNA was undetectable. However, TNF-α (50ng/ml) induced ICAM-1 mRNA within two hours, peak expression being reached between four and eight hours after initiation of treatment. The present report demonstrates for the first time that amnion derived cells can express ICAM-1 and, further, that this expression is regulated by pro-inflammatory cytokines. This has implications for the amnion as a possible source for soluble ICAM-1, for this gene product as a marker for preterm labour, and for participation of the amnion, additional to its reported secretory role, in inflammatory processes of the fetal membranes.
