  • Title: Collagen of fibrocartilage: a distinctive molecular phenotype in bovine meniscus.
    Author: Eyre DR, Wu JJ.
    Journal: FEBS Lett; 1983 Jul 25; 158(2):265-70. PubMed ID: 6688225.
    Abstract:
    Fibrocartilage of bovine knee meniscus was analyzed for major and minor collagen constituents. The main fraction (approximately 98%) of pepsin-solubilized collagen consisted of type I with a small proportion (less than 10%) of type III molecules. The minor fraction (1--2%) isolated by salt precipitation could be further resolved into type V collagen that consisted of alpha 1(V) and alpha 2(V) chains and a type II-like molecule with chains that had all the characteristics of the 3 alpha variant of alpha 1(II) found in hyaline cartilage. The articular surface zone of the meniscus appeared 2--3-fold enriched in these minor collagens compared with deeper tissue, though qualitatively the same distinctive collagen phenotype was evident throughout.
