内蒙古绒山羊毛囊形态发生规律

以胚胎龄40~110 d内蒙古二郎山绒山羊胚胎体侧部皮肤为材料，通过石蜡切片、HE染色，研究绒山羊胚胎毛囊形态发生规律。结果显示，内蒙古绒山羊胚胎皮肤初级毛囊形态发生经历毛基板前期、毛基板期、毛芽期、毛钉期和毛囊期5个时期，这5个时期又可根据其形态结构的差异划分为不同的亚期，内蒙古绒山羊胚胎皮肤初级毛囊形态发生与汗腺的发生相伴随；内蒙古绒山羊皮肤初级毛囊形态发生是分批进行的。在胚胎龄40~110 d内蒙古绒山羊胚胎体侧部皮肤未观察到次级毛囊的发生。

Hair Follicle Morghogenesis in Inner Mongolian Cashmere Goat Embryos

We systematically analyzed hair follicle morphogenesis of Inner Mongolia Cashmere Goat embryos during Ed40-Ed110 by conventional histological section and HE staining. The results suggested as following:Morphogenesis of Inner Mongolia Cashmere goat hair follicle can be divided into pre placode stage, hair placode stage, hair germ stage, hair peg stage and hair follicle stage, according to the different morphs those five stages can be divided different sub stage, and the hair follicle morphogenesis is accompanied by the occurrence of sweat gland. The process of Cashmere goat primary hair follicle morphogenesis is not synchronous, and there is a time gap. The secondary hair follicle does not appear before Ed110 of Cashmere goat fetal.
