One of the most common causes of bone graft rejection is lack of a vascular network connecting the graft to the existing native tissue – allowing for nutrient flow. Under current grafting techniques, the existing blood vessel network in the patient slowly invades the implant in order to supply the injured site with its necessary nutrients. The purpose of this research is to determine if a synthetic bone graft with a stable microvascular network can be developed in vitro. I hypothesize that the use of indirect angiogenic factors such as sonic hedgehog homolog and hypoxia-inducible factor-1 in combination with the …

Extracellular Matrix-Derived Modular Bioscaffolds For Soft Connective Tissue Regeneration, Pascal Morissette Martin
Electronic Thesis and Dissertation Repository
Human decellularized adipose tissue (DAT) represents a promising extracellular matrix (ECM) source for the development of biomaterials, with its properties conductive of angiogenesis, adipogenesis, and scaffold remodelling. This thesis sought to provide new fundamental insight into the design of ECM-derived bioscaffolds by developing novel modular biomaterials for soft connective tissue regeneration and by studying the effects of ECM composition on cell function and fate.
Initial studies explored the effects of ECM composition of pre-assembled bead foams derived from DAT or commercially-sourced bovine collagen (COL) on human wound edge dermal fibroblasts (weDFs) sourced from chronic wounds. In vitro testing under conditions …

Bioengineering Extracellular Matrix Scaffolds For Volumetric Muscle Loss, Kevin Roberts
Graduate Theses and Dissertations
Volumetric muscle loss overwhelms skeletal muscle’s ordinarily capable regenerative machinery, resulting in fibrosis and severe functional deficits which have defied clinical repair strategies. My work spans the design and preclinical evaluation of implants intended to drive the cell community of injured muscle toward a regenerative state, as well as the development of an understanding of the molecular responses of this cell community to biomaterial interventions. I demonstrate a new class of biomaterial by leveraging the productive capacity of sacrificial hollow fiber membrane cell culture; I show specifically that unique threads of whole extracellular matrix can be isolated by solvent degradation …
