Abstract
Titanium is the only metal to which osteoblasts can adhere and on which they can grow and form bone tissue in vivo, resulting in a strong bond between the implant and living bone. This discovery provides the basis for the universal medical application of Ti. However, the biochemical mechanism of bond formation is still unknown. We aimed to elucidate the mechanism of bond formation between collagen, which constitutes the main organic component of bone, and TiO2, of which the entire surface of pure Ti is composed. We analysed the binding between the soluble collagen and TiO2 by chromatography with a column packed with Ti beads of 45 µm, and we explored the association between collagen fibrils and TiO2 (anatase) powders of 0.2 µm. We ran the column of chromatography under various elution conditions. We demonstrated that there is a unique binding affinity between Ti and collagen. This binding capacity was not changed even in the presence of the dissociative solvent 2M urea, but it decreased after heat denaturation of collagen, suggesting the contribution of the triple-helical structure. We propose a possible role of periodically occurring polar amino acids and the collagen molecules in the binding with TiO2.

Abstract
Extracellular matrix components play an important role in modulating cellular activity. To study such capacities of the matrix, fibroblasts are frequently cultured in a three-dimensional gel and contraction is assessed as a measure of cellular activity. Since a connective tissue contains several types of collagen, we investigated the effect of gels composed of collagen I alone or in combination with 10% collagen III and/or 5% collagen V on contraction by human periodontal ligament fibroblasts. Gels containing collagen V contracted much faster than those without this type of collagen. Blocking of the integrin beta1-subunit with an activity-blocking antibody delayed (gels with collagen V) or almost completely blocked (gels without collagen V) contraction. Use of an antibody directed against integrin alpha2beta1 resulted in delay of gel contraction for gels both with and without collagen V. Anti-integrin alpha v beta3 or RGD peptides partially blocked contraction of gels containing collagen V, but had no effect on gels consisting of collagen I alone. The beta1-containing integrins are involved in the basal contraction by fibroblasts that bind to collagens I and III. The enhanced contraction, stimulated by collagen V, appears to be mediated by integrin alpha v beta3. We conclude that collagen V may play an important modulating role in connective tissue contraction. Such a modulation may occur during the initial stages of wound healing and/or tissue regeneration.

Abstract
Previous studies have reported that type V collagen is an anti-adhesive substrate for cultured cells in that the cells detach from culture dishes coated with type V collagen molecules or polypeptides derived from them. We have noticed that human fetal lung fibroblasts (TIG-1) initially show no reduction in adherence to and spreading on a dish coated with reconstituted type V collagen fibrils but eventually detach from the dish and form cell clumps. To determine the way in which reconstituted type V collagen fibrils are involved in cell clump formation, we have followed the fate of the fluorescence of type V collagen fibrils pre-labeled with fluorescein isothiocyanate. Essentially, all the fluorescence disappeared from the dish surface as the cells detached and was condensed in the cell clumps. The cells that were recovered from clumps and dissociated into separate cells by trypsin treatment proliferated normally after they were seeded on a bare culture dish. This result and those from gel electrophoresis, fluorescence microscopy, and a cell proliferation assay indicate that the cell detachment from the dish is not caused by cell necrosis or apoptosis but by cellular motility together with the unique features of type V collagen fibrils. Not only the adherence of type V collagen fibrils to TIG-1 cells is much stronger than that to the culture dish, but the fibrils are retained on the cellular surface. The strong adherence of type V collagen fibrils to cells plays a role in cementing TIG-1 cells together.

Abstract
Collagens represent a large family (25 members identified so far) of closely related proteins. While the preparative procedures for the members that are ubiquitous and present in tissues in large quantities (typically fibre and network forming collagens types I, II, III, IV and V) are well established, the procedures for more recently discovered minor collagen types, namely those possessing large non-collagenous domain(s) in their molecule, are mostly micropreparative and for some collagenous proteins even do not exist. The reason is that the proof of their existence is based on immunochemical staining of tissue slices and nucleic database searching. Methods of preparation and identification of constituting alpha-polypeptide chains as well as collagenous and non-collagenous domains are also reviewed. Methods for revealing non-enzymatic posttranslational modifications (particularly of the fibre forming collagen types) are briefly described as well.

Abstract
Current techniques used for collagen alpha-chains and their CNBr fragments are reviewed. Ion exchange, gel permeation, reversed-phase and affinity chromatography are discussed mainly from the preparative aspects as these are both the techniques of choice to remove biological matrix contaminants always present in collagen preparations and techniques routinely used for preparative purposes. Among electromigration procedures gel electrophoresis is widely used both for intact collagen alpha-chains and their fragments. Recently this technique was applied also for miniaturised preparations. Immunoblotting techniques serve more specific detection of otherwise hard to distinguish different collagen polypeptide chains. Capillary electromigration techniques brought recently new aspects of understanding the behaviour of collagen proteins upon different separation modes and seem to represent a smart perspective for better quantitation of individual collagen species.

Abstract
The collagens produced by chick embryo chondrocytes cultured in alginate beads were investigated both biochemically and ultrastructurally. The cartilage phenotype is maintained for at least 14 days, as indicated by the production of the cartilage-specific collagens II, IX, and XI and the absence of collagen I. There were differences in the distributions of collagens among the three different compartments analyzed (cells and their associated matrix, further-removed matrix (released by alginate solubilization), and culture medium), with large amounts of collagen IX (mainly in proteoglycan form) in the culture medium. Inhibition of lysyl oxidase activity by beta-aminopropionitrile led to an overall decrease in collagen production. In contrast to the biochemical observations, collagen ultrastructure in the extracellular matrix of alginate cultures was not in the form of the expected 64-nm banded fibrils, but rather in the form of segment-long-spacing-like crystallites. This abnormal structure is likely to be a result of alginate disrupting normal assembly. We conclude that, in this system, the native fibrillar structure of the collagenous matrix is not essential for the maintenance of the differentiated phenotype of chondrocytes.
