Expression of melatonin receptor 1A (MT1) and melatonin receptor 1B (MT2) in thymuses of non‐pregnant and pregnant ewes. (a) Expression values of MT1 and MT2 mRNA in the thymus. (b) Expression of MT1 and MT2 proteins in the thymus. (c) Representative immunohistochemical localization of MT2 protein in the thymuses. The thymus is divided into the cortex (CO) and the medulla (ME). Note: HE = stained by haematoxylin and eosin; Ctl = negative control; DN16 = day 16 of the oestrous cycle; DP13 = day 13 of pregnancy; DP16 = day 16 of pregnancy; DP25 = day 25 of pregnancy; T = thymocyte; ER = epithelial reticular cell; CA = capillary; TC = thymic corpuscle. Scale bar: 20 µm. P < 0·05 indicates significant difference.
