Graphs represent 3 experimental replicates from 4 biological donors of TOs (circles, squares, triangles, and diamonds) and 3 biological donors of DOs (circles, squares, and triangles). Data presented as mean values ± SEM. C Conditioned media were collected from TO cultures from 3 biological donors at 1-, 24-, 48-, and 72-h post-passage and secreted IL-27 was measured via human IL-27 ELISA. Graph represents 5 experimental replicates per timepoint for donor 1 TOs (circles); Graph represents 3 experimental replicates per timepoint for donor 2 and 3 TOs (squares, triangles). Data presented as mean values ± SD.

White box indicates zoom inset and white dashed line demarcates regions of cytotrophoblasts (CTB) and syncytiotrophoblasts (STB). 20X magnification, Z-stack, merged. Scale bar, 100μm. Images representative experiments independently repeated in 4 biological TO donors with similar results. E. TOs from 2 biological donors (circles, diamonds) were pre-treated with neutralizing antibodies prior to infection with <t>ZIKV-CAM,</t> as described in Supplementary Fig. , .
