Summary

In 48h incubation L-929 (L-5) cells secreted collagenous protein accounting for 16% of the total protein. CM-chromatography, SDS-acrylamide gel electrophoresis and DEAE-cellulose chromatography revealed that the collagenous protein was mainly composed of type I collagen, having no collagen of type III.

In addition, precursor-form collagen and tropocollagen molecules were found to be present in the incubate.

Zusammenfassung

L-929 (L-5) Mausfibroblasten synthetisieren bei einer 48-stündigen in vitro Inkubation kollagene Proteine mit einem Anteil von 16% am Gesamtprotein. Mit CM-Chromatographie, SDS-acrylamidgelelektrophorese und DEAE-Chromatographie wurde gezeigt, daß praktisch ausschließlich Typ I Kollagen synthetisiert wird, während Typ III Kollagen nicht nachweisbar ist. Zusätzlich fanden sich Kollagenvorläufer und Tropokollagen im Inkubationsmedium.
