内蒙古阿尔巴斯绒山羊毛囊结构及形态发生过程研究

 【目的】了解绒山羊毛囊的组织结构及毛囊形态发生变化过程，为研究绒山羊绒毛发育的分子调控机理奠定组织学基础。【方法】制作内蒙古阿尔巴斯绒山羊胚胎皮肤组织切片，显微镜下观察照相。【结果】绒山羊的毛囊结构同其它动物一样，由毛球、连接组织鞘、外根鞘、内根鞘和毛干几部分组成。在胎龄55～65 d毛囊开始发生形成毛芽；胎龄135 d，大多数初级毛囊和一部分次级毛囊发育基本成熟；次级毛囊是初级毛囊的一个分支。【结论】了解了绒山羊毛囊的结构组成及毛囊从发生到发育成熟的整个形态变化过程，为相关领域研究者提供借鉴。

Study on Hair Follicle Structure and Morphogenesis of the Inner Mongolian Arbas Cashmere Goat

Objective] The objective of this study was to observe the hair follicle structure and Morphogenesis of cashmere goat. Method] Observation embryonic skin paraffin section of the Inner Mongolian Arbas cashmere goat by light microscope. Result] The hair follicle structure of cashmere goat was in the same manner compared with other animals, which was composed of hair bulb, connective tissue sheath, outer root sheath, inner root sheath and hair shaft. Hair germ was formed at the embryonic age of 55-65 days. Most primary hair follicles and some secondary follicles matured at the embryonic age of 135 days. Moreover, an important fact that secondary hair follicle is a branch of primary hair follicle has been found first on cashmere goat. Conclusion] This study described the structure and changeable process morphogenesis of hair follicle, that aid service as a basic introduction into the field of cashmere goat hair follicle morphogenesis.
