Pituitary thyrotropes were identified throughout the year in the hibernating bat Myotis lucifugus lucifugus by means of light microscopic immunohistochemistry. These cells occupied a small proportion of the volume of the pars distalis (mean = 1.36% in males; mean = 1.52% in females) and exhibited a limited distribution pattern that was characteristic of all animals examined. Cells that were immunoreactive with an antiserum directed against the beta subunit of thyroid-stimulating hormone were most numerous in the median rostral and ventral regions; they were scarce or absent in the dorsal portion of the gland and in the extreme lateral wings. No significant seasonal variations were observed in this cell population in females. In males, however, immunoreactive thyrotropes occupied a significantly larger proportion of the pars distalis in June (following arousal from hibernation than at other times of year. No evidence of involution was observed in these anterior pituitary cells in either males or females during hibernation.
通过光学显微镜免疫组织化学方法，全年都能在冬眠的蝙蝠（棕蝠指名亚种）中识别出垂体促甲状腺细胞。这些细胞在远侧部中所占体积比例较小（雄性平均为1.36%；雌性平均为1.52%），并且呈现出一种有限的分布模式，这是所有被检查动物的特征。与抗促甲状腺激素β亚基抗血清发生免疫反应的细胞在吻端中部和腹侧区域最多；在腺体的背侧部分和最外侧翼中稀少或不存在。在雌性中，该细胞群体未观察到明显的季节性变化。然而，在雄性中，6月（从冬眠苏醒后）促甲状腺免疫反应细胞在远侧部中所占比例明显大于一年中的其他时间。在冬眠期间，无论是雄性还是雌性，这些垂体前叶细胞均未观察到退化迹象。
