Nanoscale Stiffness Cues Influence Valvular Interstitial Cell Activation To Myofibroblasts, Michaela Wenning Jan 2019

Nanoscale Stiffness Cues Influence Valvular Interstitial Cell Activation To Myofibroblasts, Michaela Wenning

Undergraduate Honors Theses

Surgery is currently the primary treatment option for aortic valve stenosis (AVS) patients, many of whom are ineligible for surgery and are left untreated. AVS is progression is known to differ between males and females, and an understanding of sex-specific mechanisms of disease progression is imperative in developing accurate treatment options for men and women. The development of a nonsurgical therapy for AVS patients requires a deeper understanding of the molecular and cellular mechanisms of AVS progression. Currently, the role of calcium phosphate nanoparticles detected in the aortic valve during early stages of AVS in influencing disease progression and valvular ...


Modeling Hypertrophic Cardiomyopathy In Neonatal Cardiomyocytes In Cultured In 3d, Esther Choi Jan 2018

Modeling Hypertrophic Cardiomyopathy In Neonatal Cardiomyocytes In Cultured In 3d, Esther Choi

Undergraduate Honors Theses

Heart disease continues to be the leading cause of death in both men and women. It is accompanied with cellular- and organ- level remodeling that cannot be mimicked or recaptured by cells on standard culture platforms. Polyethylene glycol hydrogels bridge this gap by providing user-defined tunability for cell culture. A novel 3D cell culture system was developed to encapsulate neonatal rat ventricular cardiomyocytes (NRVMs) in a single plane, and cell health was assessed. In parallel, recombinant adenoviruses containing the mutations responsible for human hypertrophic cardiomyopathy (HCM) in the beta myosin gene (R403Q and R453C) were generated and used as a ...


Epithelial-Mesenchymal Crosstalk Influences Cancer-Related Cell Behavior: A 3d Lung Alveolus-Fibroblast Co-Culture System, Jessica Kole Hall Jan 2017

Epithelial-Mesenchymal Crosstalk Influences Cancer-Related Cell Behavior: A 3d Lung Alveolus-Fibroblast Co-Culture System, Jessica Kole Hall

Undergraduate Honors Theses

Lung cancer is a devastating disease that kills more individuals in the United States than any other cancer. The tumor microenvironment is increasingly recognized as playing a major role in the progression of cancer. Thus, studying the interactions among lung cancer cells, non-malignant cells and the surrounding matrix is critical for understanding and treating lung cancer. Three-dimensional in vitro co-culture systems allow for tissue-relevant platforms that better recapitulate the native cell environment. In this work, we employed a cyst templating technique to culture alveolar epithelial cells on photodegradable microspheres and subsequently encapsulated the cell-covered spheres within poly(ethylene glycol) (PEG ...
