为探讨牦牛不同解剖部位脂肪组织的形态结构,本研究采集了5 头4 岁左右公牦牛的皮下脂肪、肌间脂肪及肾周脂肪样本,采用H&E染色法观察组织细胞形态,统计与计算了单位面积内的细胞数量与平均细胞面积.结果表明,牦牛脂肪组织呈现典型的蜂窝状结构,细胞面积较大.皮下脂肪、肌间脂肪及肾周脂肪的平均细胞面积分别为(1 513.08±167.87)μm2、(1 367.80±152.79)μm2 和(1 872.67±413.00)μm2.研究结果为进一步深入研究牦牛脂肪组织提供了基础数据支持.
This study aimed to investigate the morphological characteristics of various adipose tissues in yaks.Samples of subcutaneous,intermuscular,and perirenal adipose tissues were collected from five male yaks,each ap-proximately four years old.Histological analysis was performed using Hematoxylin and Eosin(H&E)staining to ex-amine cellular morphology and to quantify the number of cells per unit area as well as the average cell size.The re-sults revealed that yak adipose tissues exhibit a honeycomb-like structure with relatively large cell sizes.The aver-age cell areas of subcutaneous,intermuscular,and perirenal adipose tissues were(1 513.08±167.87)μm2,(1 367.80±152.79)μm2,and(1 872.67±413.0)μm2,respectively.These findings provide valuable ref-erence data for further research on yak adipose tissues.
