牦牛不同部位脂肪组织的形态结构观察

Observation of Morphological Structure in Different Adipose Tissues of Yak

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(1513.08±167.87)μm^(2)、(1367.80±152.79)μm^(2)和(1872.67±413.00)μm^(2)。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 approximately four years old.Histological analysis was performed using Hematoxylin and Eosin(H&E)staining to examine cellular morphology and to quantify the number of cells per unit area as well as the average cell size.The results revealed that yak adipose tissues exhibit a honeycomb-like structure with relatively large cell sizes.The average cell areas of subcutaneous,intermuscular,and perirenal adipose tissues were(1513.08±167.87)μm^(2),(1367.80±152.79)μm^(2),and(1872.67±413.0)μm^(2),respectively.These findings provide valuable reference data for further research on yak adipose tissues.
