Design Of A Modular Endothelialized Platform For Vascularized Bone Regeneration, Kevin Barrett Miles

Wayne State University Dissertations

The gold standard for bone regeneration requires harvesting a piece of healthy bone from the patient through a painful procedure, but this piece of autologous bone graft contains the bone and endothelial cells required to rapidly regenerate bone in a defect. We have developed a modular bone regeneration platform, composed of mesenchymal stem cells (MSCs) and hydroxyapatite (HAP) microgranules encapsulated in microcapsules, to replace autologous graft harvesting. The microcapsules are composed of a polyelectrolyte membrane formed by the ionic-complex reaction between chondroitin 4-sulfate (C4S) and chitosan. The specific aims of this thesis were to 1) examine the ability of C4S/HAP/chitosan …

Study Of Molecular Interactions Of Glycosaminoglycans And Glycosaminoglycan Mimetics With Their Protein Targets, Daniel K. Afosah

Theses and Dissertations

Glycosaminoglycans (GAGs) are complex linear chain carbohydrate molecules found on virtually all animal cell surfaces. Owing to their negatively charged nature, GAGs interact with a number of different proteins. Thus, although they have great potential as therapeutic agents, their apparent promiscuous interactions increase their side effect risk. GAG mimetics, including GAG oligosaccharides and non-saccharide GAG mimetics (NSGMs) are viable approaches to address this. This work discusses sulfated benzofuran thrombin inhibitors with submaximal protease inhibition, sulfated diflavonoid inhibitors of plasmin and GAG oligosaccharides with selectivity for human neutrophil elastase (HNE).

Anticoagulants are very important for the treatment of thrombotic diseases. The …
