The Role Of Obesity And Dietary Fatty Acid Content In Regulating Humeral Bone And Cartilage Homeostasis, Lauren Votava

McKelvey School of Engineering Theses & Dissertations

Objective: The goal of this study was to investigate the effects of different dietary fatty acids in the context of diet-induced obesity on bone and cartilage in the humerus. It is known that obesity increases the severity of injury-induced osteoarthritis in the knee, however it is not fully understood what pathological changes have occurred due to diet alone¹. Additionally, while it is known that shoulder osteoarthritis has a link to obesity, the alterations in this joint are incompletely described.

Methods: In order to examine diet-induced changes in both bone and cartilage, this research utilized mice that had been …

Osteon Mimetic Scaffolding, Janay Clytus

Senior Theses

The purpose of this research is to provide an alternative to naturally derived bone grafts. There is a gap in the supply of donors and the demand of bone tissue. Artificial scaffold creation can work as an implant and decrease the shortage of bone grafts and increase the range of injuries that can be repaired. Current research focuses on optimizing mechanical properties such as porosity, improving vascularization using cells, and generating osteoconductivity. For osteodifferentiation, mesenchymal stem cells (MSCs) can differentiate into mesodermal lineages such as chondrocytes, osteoblasts, adipocytes, and tenocytes by supplementing cultures with lineage-specific soluble factors (Marchetti). Co-culturing ECFCs …
