Fig 2: (A) Concentrations of a) eotaxin and b) lymphotactin in the bovine luteal tissues from the cyclic and pregnant stages evaluated by ELISA. Data are means ± SEM for four cows per stage. a,b Bars without a common letter differ (P < 0.05 or lower). (B) Localization of a) CCR3 and b) XCR1 in the bovine CL evaluated by immunohistochemistry. Intensive immunoreactivity was observed in luteal cells (black arrowheads) and endothelial cells (white arrowheads). No positive immunoreactivity was observed in the negative control (inserted panels). Scale bar = 50 µm.
