Localization of type III procollagen mRNA in human liver was studied by in situ hybridization using human alpha 1(III) procollagen cDNA. Frozen and paraformaldehyde-fixed sections of biopsied human liver from patients with chronic hepatitis and cirrhosis were examined using the digoxigenin-labeled cDNA probe. Localization of the type III procollagen mRNA was demonstrated not only in the cytoplasm of mesenchymal cells but also in a large number of hepatocytes, in proportion to the extent of fibrosis. These results suggest that hepatocytes play an important role in fibrogenesis in the liver.

D008103	Liver Cirrhosis	Liver disease in which the normal microcirculation, the gross vascular anatomy, and the hepatic architecture have been variably destroyed and altered with fibrous septa surrounding regenerated or regenerating parenchymal nodules.

D009693	Nucleic Acid Hybridization	Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D006525	Hepatitis, Viral, Human	INFLAMMATION of the LIVER in humans due to infection by VIRUSES. There are several significant types of human viral hepatitis with infection caused by enteric-transmission (HEPATITIS A; HEPATITIS E) or blood transfusion (HEPATITIS B; HEPATITIS C; and HEPATITIS D).

D006526	Hepatitis C	INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.
