Degradable emulsion-templated scaffolds for tissue engineering from thiol–ene photopolymerisation

Emulsion templated scaffolds with tunable mechanical properties for bone tissue engineering

Polymerised High Internal Phase Emulsions (PolyHIPEs) are manufactured via emulsion templating and exhibit a highly interconnected microporosity. These materials are commonly used as thin membranes for 3D cell culture. This study uses emulsion templating in combination with microstereolithography to fabricate PolyHIPE scaffolds with a tightly controlled and reproducible architecture. This combi...

Multilayer micromolding of degradable polymer tissue engineering scaffolds

Precise surface geometrical morphologies have been shown to improve cellular proliferation, adhesion, and functionality. It has been found that cells respond strongly to feature dimensions a fraction of their size. In this paper, soft lithography techniques were applied to microfabricate polydimethylsiloxane molds with precisely controlled micro-scale patterns. Three-dimensional polycaprolacton...

Aligned and random nanofibrous nanocomposite scaffolds for bone tissue engineering

Aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (PCL), poly (vinyl alcohol) (PVA) and hydroxyapatite nanoparticles (nHA). The morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. Scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...

A Review on Commonly Used Scaffolds in Tissue Engineering for Bone Tissue Regeneration

Introduction: Bone is one of the tissues that have a true potential for regeneration. However, sometimes the bone defects are so outsized that there is no chance of bone self-repair and restoration or the damage is such that it is not possible to repair with medical or surgical interventions. In these situations, bone grafts are the treatment of choice, but due to several obstacles, including l...
