Preparation of mesh-like collagen scaffolds for tissue engineering

Collagen–based scaffolds for skin tissue engineering

The aim of this study was to obtain four collagen based porous scaffolds and to assess their in vitro biocompatibility and biodegradability in order to use them for skin tissue engineering. We have prepared four variants of collagen-based biodegradable sponges by liophilization of type I collagen solution and three variants of collagen-agarose mixture in different ratios 2:1 (A), 1:1 (B) and 1:...

Oriented Collagen Scaffolds for Tissue Engineering

Oriented collagen scaffolds were developed in the form of sheet, mesh and tube by arraying flow-oriented collagen string gels and dehydrating the arrayed gels. The developed collagen scaffolds can be any practical size with any direction of orientation for tissue engineering applications. The birefringence of the collagen scaffolds was quantitatively analyzed by parallel Nicols method. Since na...

Collagen—Dexamethasone and Collagen-D3 Scaffolds for Bone Tissue Engineering

The aim of the study was to test the biocompatibility and osteoinductive potential of collagen with dexamethasone (Dex) and collagen with 1, 25 dihydroxycholecalciferol (D3) scaffolds on two human osteoblast cell lines, MG63 and hFOB1.19. The cell morphology was examined by SEM, the scaffolds colonization was monitored by fluorescence microscopy, viability by MTT assay and cells differentiation...

Hydroxyapatite-reinforced Collagen Tissue Engineering Scaffolds

by Robert J. Kane Scaffolds have been fabricated from a wide variety of materials and most have showed some success, either as bone graft substitutes or as tissue engineering scaffolds. However, all current scaffold compositions and architectures suffer from one or more flaws including poor mechanical properties, lack of biological response, non-degradability, or a scaffold architecture not con...
