title: [Identification of procollagen mRNA in chronic active hepatitis B].
abstract: In situ hybridization is a tool for staining intracellular procollagen mRNAs with specific probes. Our study shows the amounts of procollagen mRNAs of types I and III to be increased in liver biopsies of five patients with chronic active hepatitis B as compared with five healthy controls. Parallel staining employing anti-smooth-muscle-actin antibodies was able to identify myofibroblast-like cells at the same localization where procollagen mRNAs were found. Consequently, these transformed Ito-cells might be the procollagen-producing cells.
