随着分子生物学和细胞生物学的进展,人们对肝脏各种类型细胞的功能和结构也有了更进一步的了解。肝脏的功能就是肝脏各型细胞功能的总和。然而以往人们常把肝脏功能与肝细胞的功能相混淆,忽视了肝脏非实质细胞的功能。本文仅就肝脏非实质细胞的种类和特异功能作一简述。一、肝脏细胞的种类肝脏细胞分为肝实质细胞和非实质细胞,非实质细胞又可分为:肝窦内皮细胞、枯否氏细胞、Ito细胞和隐窝细胞。它们在整个肝脏细胞中(除外胆管细胞和血管细
With the progress of molecular biology and cell biology, people also have a better understanding of the function and structure of various types of cells in the liver. The function of the liver is the sum of the functions of various types of cells in the liver. However, in the past, people often confused liver function with liver cell function, neglecting the function of liver non-parenchymal cells. This article only a brief description of the types of liver non-parenchymal cells and specific functions. First, the type of liver cells Liver cells are divided into hepatic parenchymal cells and non-parenchymal cells, non-parenchymal cells can be divided into: sinusoidal endothelial cells, Kupffer cells, Ito cells and crypt cells. They are throughout the liver cells (except for cholangiocytes and blood vessels)
