Influence of cell density on collagen biosynthesis in fibroblast cultures [PDF]
Biochemical Journal, 1982 Characteristic features of collagen metabolism in human skin fibroblasts were studied in relation to cell density. Measuring peptide-bound hydroxyproline we found that collagen synthesis per cell decreased when cultures approached confluency. On the other hand, the relative rate of collagen synthesis (collagen/total protein) was higher in quiescent ...

Effect of Low-Temperature Plasma Jet on Thermal Stability and Physical Structure of Type I Collagen [PDF]
, 2012 This work is devoted to the characterization of type I collagen treated by a low-temperature plasma jet generated in ambient air to determine whether the resulting fibrous material is structurally preserved or reinforced.

Mechanical properties of collagen fibrils [PDF]
, 2007 The formation of collagen fibers from staggered subfibrils still lacks a universally accepted model. Determining the mechanical properties of single collagen fibrils ( diameter 50 - 200 nm) provides new insights into collagen structure. In this work, the

Contribution of postnatal collagen reorientation to depth-dependent mechanical properties of articular cartilage [PDF]
, 2011 The collagen fibril network is an important factor for the depth-dependent mechanical behaviour of adult articular cartilage (AC). Recent studies show that collagen orientation is parallel to the articular surface throughout the tissue depth in perinatal

Alginate Conjugation Increases Toughness in Auricular Chondrocyte Seeded Collagen Hydrogels
Bioengineering, 2023 Current auricular cartilage replacements for pediatric microtia fail to address the need for long-term integration and neocartilage formation. While collagen hydrogels have been successful in fostering neocartilage formation, the toughness and ...

Increase in types IV and VI collagen in cherry haemangiomas [PDF]
, 1992 The capillaries in cherry haemangiomas show perivascular hyalinized sheaths. In order to clarify the nature of this sheath material, the extracellular matrix of cherry haemangiomas from 20 normal volunteers (age range 30-64 years) was investigated using ...

Immunohistochemical localization of collagen types I and VI in human skin wounds [PDF]
, 1996 A total of 74 human skin wounds were investigated and collagen types I and VI were localized in the wound area by immunohistochemistry. Collagen type I appeared in the form of ramifying string-like structures after approximately 5–6 days, but positive ...

Nonuniform distribution of collagen density in human knee ligaments
Journal of Orthopaedic Research, 1994 AbstractIt is generally recognized that the mechanical properties of soft connective tissues are affected by their structural components. We documented collagen density distributions in human knee ligaments to quantify differences in density within and between these ligaments.

Second harmonic generation confocal microscopy of collagen type I from rat tendon cryosections [PDF]
, 2006 We performed second harmonic generation (SHG) imaging of collagen in rat-tendon cryosections, using femtosecond laser scanning confocal microscopy, both in backscattering and transmission geometries.
