Density–property relationships in collagen–glycosaminoglycan scaffolds

Acta Biomaterialia, 2010
Collagen-glycosaminoglycan scaffolds for the regeneration of skin have previously been fabricated by freeze-drying a slurry containing a co-precipitate of collagen and glycosaminoglycan. The mechanical properties of the scaffold are low (e.g. the dry compressive Young's modulus is roughly 30kPa and the dry compressive strength is roughly 5kPa).

Crosslinking density and resorption of dimethyl suberimidate-treated collagen

Journal of Biomedical Materials Research, 1997
Collagen was purified from bovine Achilles tendon and crosslinked with dimethyl suberimidate (DMS) and glutaraldehyde (GTA). Under optimal conditions, the shrinkage temperature (Ts) was raised to 74 degrees C for collagen crosslinked with DMS and to 80 degrees C for those crosslinked with GTA.

Density–property relationships in mineralized collagen–glycosaminoglycan scaffolds

Acta Biomaterialia, 2009
Mineralized collagen-glycosminoglycan scaffolds have previously been fabricated by freeze-drying a slurry containing a co-precipitate of calcium phosphate, collagen and glycosaminoglycan. The mechanical properties of the scaffold are low (e.g. the dry Young's modulus for a 50 wt.% mineralized scaffold is roughly 780 kPa).

Densities of collagen dehydrated by some organic solvents

Experientia, 1966
Der Einfluss von organischen Losungsmitteln auf die Dichteveranderungen des Kollagens wurde gepruft. Methanol und Butanol fuhrt zur Strukturauflockerung, Aceton und Dioxan zur Strukturverdichtung.

The distribution of electron density in corneal collagen fibrils

Current Eye Research, 1981
Using high intensity synchrotron X-ray diffraction data, an electron density profile has been obtained for the collagen fibrils in corneal stroma at higher resolution than has been possible before. The details within this electron density distribution are discussed in terms of the collagen and its interactions with other components present in the ...

Increased dermal collagen density in amyotrophic lateral sclerosis

Journal of the Neurological Sciences, 1988
We examined specimens of skin overlying the sacral region, among the most common sites of bedsores, from patients with amyotrophic lateral sclerosis (ALS) and controls, and found that in ALS patients, collagen fibrils had a greater density and became more tightly packed with the duration of illness.

Hydrodynamic Shear and Collagen Receptor Density Determine the Adhesion Capacity of S. aureus to Collagen

Annals of Biomedical Engineering, 2001
Dynamic bacterial adhesion has recently gained significant attention due to its role in the initiation of infectious diseases. Staphylococcus aureus binding to collagen has been shown to be an important event in the pathogenesis of infection. Staphylococcal strains have exhibited wide variability in their level of collagen binding, which may be a ...

Improved In Vitro Angiogenesis Model by Collagen Density Reduction and the Use of Type III Collagen

Annals of Plastic Surgery, 1993
Angiogenesis was examined by a three-dimensional model in vitro, using human umbilical vein endothelial cells (HUVECs) cultured in a collagen gel. An abundant capillary-like network with a lumen structure was identified histologically and shown to have formed at a collagen density of 0.05% or 0.10% instead of 0.15%, for either type I or type III ...

Characterization of vascular density and collagenous matrix in oral pleomorphic adenomas

Minerva Stomatologica, 2020
Tumor vascular density and collagen matrix organization are critical factors to neoplasia development and progression. This study aimed to analyze the variables associated with the extracellular matrix in oral pleomorphic adenomas.This cross-sectional study comparatively evaluated 21 cases of pleomorphic adenomas and 21 sections of regular oral mucosa ...
