In vitro secretion of IL-1β in amnion and choriodecidua regions after selective stimulation with Escherichia coli. IL-1β secreted to the culture medium after 24 h of infection with 1 × 106 CFU of E. coli. Data were normalized in function of protein concentration (pg/μg protein) and each bar represents the 95% confidence intervals and the median (solid line) of 10 different experiments. Significant difference between basal and stimulated values is indicated (*P < 0.05) C. Choriodecidua; A. Amnion.
