Abstract The aim of the study was to examine the stimulatory effect of the inflammatory agent lipopolysac-charide
(LPS) on the capacity of human term placenta to secrete interleukin (IL)-15 and IL-18. Isolated placental
cotyledons from normal human term deliveries were dually perfused for ten hours with perfusion medium alone
(n = 5) or with perfusion medium containing LPS (1 lg/kg perfused placental tissue) (n = 5). Placental tissue was
collected from three different placental compartments (amnion, chorion, and placenta) before and after perfusion.
The placental tissues collected were homogenized and examined for IL-15 and IL-18 by… More >
