A) Analysis of LXR and RXRα co-expression in decidua; LXR expression is shown in red, RXRα expression is visualized in green, synchronized expression of both nuclear receptors is shown (yellow, marked by arrows); in addition, to cells showing co-expression, we also found singular expression of LXR (red) and RXRα (green); some nuclei are negative for both receptors (blue); the identification of cell type positive for either LXR or RXRα in the decidua was achieved with HLA-G double staining; HLA-G is a marker exclusively expressed by extravillous trophoblast cells (EVT). B), HLA-G expression in green and LXR expression in red are shown; the border between decidual stroma cells and the EVT is shown as a discontinuous line; both decidual stroma cells and EVT express LXR. C) HLA-G expression in green and RXRα expression in red are shown; the border between decidual stroma cells and the EVT is shown as a discontinuous line; both decidual stroma cells and EVT express RXRα.
