Myoblast transplantation is currently limited by poor survival and integration of these cells into host musculature. Transplantation systems that enhance the viability of the cells and induce their outward migration to populate injured muscle may enhance the success of this approach to muscle regeneration. In this study, enriched populations of primary myoblasts were seeded onto delivery vehicl...

Alteration of the geometrical surface configuration of cortical bone allografts may improve incorporation into host bone. A porous biodegradable coating that would maintain immediate structural recovery and subsequently allow normal graft healing and remodeling by promoting bony ingrowth could provide an osteoconductive surface scaffold. We investigated the feasibility of augmenting cortical bo...

Treatment of coronary bifurcation lesions is common in everyday practice and accounts for ≤20% of all percutaneous coronary interventions. The treatment of these lesions with drug-eluting stents, especially when a double-stent technique is used, remains challenging and is associated with a lower procedural success and a higher rate of long-term adverse cardiac events such as stent restenosis an...

Tissue engineering attempts to address the ever widening gap between the demand and supply of organ and tissue transplants using natural and biomimetic scaffolds. The regeneration of specific tissues aided by synthetic materials is dependent on the structural and morphometric properties of the scaffold. These properties can be derived nondestructively using quantitative analysis of high resolut...

While biologically feasible, bone repair is often inadequate, particularly in cases of large defects. The search for effective bone regeneration strategies has led to the emergence of bone tissue engineering (TE) techniques. When integrating electrospinning techniques, scaffolds featuring randomly oriented or aligned fibers, characteristic of the extracellular matrix (ECM), can be fabricated. I...

An injectable hydrogel, comprised of hyaluronan and methylcellulose (HAMC), shows promise for localized, sustained delivery of growth factors for treatment of spinal cord injury (SCI). To better understand its potential for the delivery of small molecules, the release of sparingly soluble neuroprotectant, nimodipine, was investigated experimentally and via continuum modeling. This revealed that...

The aim of this study was to fabricate a fibrous scaffold that closely resembled the micro-structural architecture and mechanical properties of collagen fibres found in the anterior cruciate ligament (ACL). To achieve this aim, fibrous scaffolds were made by electrospinning L-lactide based polymers. L-Lactide was chosen primarily due to its demonstrated biocompatibility, biodegradability and hi...

In this study, a hybrid system consisting of 3D printed polycaprolactone (PCL) filled with hydrogel was developed as an application for reconstruction of long bone defects, which are innately difficult to repair due to large missing segments of bone. A 3D printed gyroid scaffold of PCL allowed a larger amount of hydrogel to be loaded within the scaffolds as compared to 3D printed mesh and honey...
