Randomized trial demonstrates collagen formation in hepatocytes, indicating potential liver fibrosis implications.

To identify the collagen synthesis capability of hepatocytes in culture and correlate it with in vivo findings.
Used immunohistochemical techniques to analyze collagen synthesis.
Maintained adult rat liver parenchymal cells in nonreplicating monolayer culture for 2 days in serum-free medium.
Localized type IV collagen in pathological rat liver slices.
Hepatocytes synthesized type IV collagen in culture within 2 days.
Type I and III interstitial collagens were also synthesized during extended culture.
Type IV collagen was found in hepatocytes of pathologic liver, suggesting a role in liver fibrosis.

Diegelmann et al. (1983) studied this question.
