摘要:应用光镜及HE染色等技术对体细胞克隆水牛的脂肪和皮肤组织及其细胞类型和形态进行了详细的观察,旨在为以后体细胞克隆牛的研究提供一定的理论依据,结果表明,脂肪组织外周有疏松结缔组织包裹,脂肪小叶不明显;皮肤由表皮和真皮构成,借助皮下组织与深部的肌肉相连,局部表皮有脱落,皮肤上有毛囊分布。

Abstract: To provide a certain basis for the study of somatic nuclear transfer buffalo, the histological structure and its cell morphology of adipose and skin tissue in somatic nuclear transfered buffalo were observed by anatomy, HE staining techniques. The results showed that the adipose tissue of somatic nuclear transfer buffalo were encapsulated by loose connective tissue, and the fat lobule was not obvious; The skin was composed of epidermis and dermis, and connected with muscle by hypodermis. Part of epidermis was abscission. There were hair follicles.
Key words: buffalo; somatic nuclear transfer; fat; skin
自從1997年体细胞克隆羊“多莉”出世以来,体细胞克隆动物已成为当前科学研究的热点之一。目前已成功克隆出了牛、羊、猪、兔等动物[1-4]。我国研究人员也在动物体细胞克隆方面进行了大量的研究。其中广西大学动物繁殖研究所就先后成功地获得了体细胞克隆水牛和体细胞克隆黄牛[5]。
本试验对出生后不幸夭折的体细胞克隆水牛进行剖检,发现小牛犊的皮肤表面无毛附着,局部皮肤脱落;脂肪组织呈黄蜡样干酪状,手捏无油性,对所取皮肤和脂肪组织进行固定,通过光镜及HE染色等技术对体细胞克隆水牛皮肤及脂肪组织结构进行了观察分析,为以后体细胞克隆水牛的研究提供必要的理论支撑。
1材料与方法
脂肪及皮肤组织取材于广西大学动物繁殖研究所的体细胞克隆水牛。此克隆水牛出生时死亡,对其进行解剖,取皮肤和脂肪组织,然后用75%的酒精固定,经脱水、透明、石蜡包埋后切片(厚度7 μm),再HE染色[6],在光镜下观察、显微摄影。……
