前言:至今,肥大细胞的正常生理功能仍旧不明。作为结缔组织的一种固有细胞成分,它广泛分布于哺乳动物组织中。组织学上是根据其胞质颗粒的异染性着色来辩认的,它们在HE染色标本中并不能显现。在经受不同的固定技术和不同的染色方法处理,有着不同的效应。揭示这些化学反应的实质,有助于了解其生理特性。肥大细胞 Foreword: To date, the normal physiological functions of mast cells remain unknown. As an intrinsic cellular component of connective tissue, it is widely distributed in mammalian tissues. Histologically, it is based on heterochromatic staining of its cytoplasmic granules, which are not found in HE-stained specimens. Have different effects when subjected to different fixation techniques and different staining methods. Revealing the essence of these chemical reactions helps to understand their physiological properties. Mast cells
