Monospecific antibodies directed against type I, type III collagens, and prolyl hydroxylase were used to clarify the process of liver fibrosis after CCl4 intoxication in rats by the direct immunoperoxidase method. In acute CCl4 intoxication, fat-storing cells (FSCs) were increased in number in the areas of necrosis around the central veins. These FSCs exhibited intense positive stainings for type I, type III collagens, and prolyl hydroxylase in well-developed rough endoplasmic reticula and Golgi apparatus. This was the direct evidence that the collagens formed after CCl4 intoxication are produced by FSCs. In chronic CCl4 intoxication, increased FSCs in and around the fibers also contained strong immunoreactive materials of both collagens and prolyl hydroxylase mainly in the rough endoplasmic reticula. These collagens were also present in the Golgi apparatus and vesicles close to the cytoplasmic membrane, demonstrating the exocytic process of collagen formation of FSCs. In contrast, faint immunoreactions of both collagens were found in the rough endoplasmic reticula and Golgi apparatus of hepatocytes during the process of fibrosis. These findings indicate that FSCs play an important role in fibrogenesis after acute and chronic CCl4 intoxication in the rat.
