摘  要：
应用免疫组织化学方法,对发育的第3.5～20.5天鸡胚腺垂体卵泡刺激素(FSH)细胞的发生及其在发育过程中的变化规律进行了研究。结果,鸡胚发育的中期(第10.5天),可观察到少量明显的FSH细胞分布于腺垂体后叶,随着胚胎的发育,FSH细胞数量显著增加(P<0.05),发育的第16.5天FSH细胞数量增加到了整个孵化期的最大值,分布于垂体后叶的腹侧,前叶仅有少量零散的FSH细胞;在发育的第18.5天至出生期FSH细胞数量显著减少。早期FSH细胞体积小、细胞浆少、细胞核大,单个或团状分布,随着胚龄的增加,细胞体积增大、细胞浆增多、细胞浆浓染。结果表明,鸡胚胎腺垂体FSH细胞发生于胚胎发育的中期,细胞的增殖和分化过程发生在胚胎发育的中后期;FSH细胞分布于垂体后叶腹侧。

摘  要：
The present study is to determine ontogeny of chick embryonic pituitary follicle-stimulating hormone(FSH) cells and their change during developing embryos.The pituitary glands were collected on day 3.5 to 20.5 of incubation,respectively.The expression and distribution of pituitary FSH cells were then detected by the immunohistochemical method.The experimental results demonstrated that scattered and clarity immunopositive FSH cells were first detected in caudal lobe of pituitary gland on day 10.5,and then dramatically increased(P<0.05).FSH cells increased to a peak on day 16.5,and distributed caudal lobe,only scattered FSH cells distributed cephalic lobe of pituitary gland.On day 18.5 FSH cells decreased.In the early stage,the volume of FSH cells was smaller,there was less cytoplasmic and bigger nuclear,and light staining;in the mid-incubation and later,the volume become bigger,the cells became intensive staining.These results suggested that the ontogeny of FSH cells is in the middle stage and that the proliferation and differentiation of FSH cells occur during middle and late stage.
