Abstract
THE collagen fibres newly formed in experimental hepatic fibrosis and pre-cirrhosis are resorbed when the noxic stimuli have been removed1. In investigating the mechanism of genesis and resorption of collagen fibres in experimental hepatic fibrosis2,3 we have found using electron microscopy that the collagen fibres are degraded extracellularly and partly engulfed by Kupffer cells and/or macrophages4,5. Within these cells digestion of collagen fibrils or degraded collagen fibrils may occur in lysosomes6.
