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 ...


The Effects Of Weak Static And Pulsed Magnetic Fields On Fibroblast And Fibrosarcoma Cells Under A Controlled Magnetic Environment, Julian Brandon Cyrus Apr 2015

The Effects Of Weak Static And Pulsed Magnetic Fields On Fibroblast And Fibrosarcoma Cells Under A Controlled Magnetic Environment, Julian Brandon Cyrus

Electrical, Computer & Energy Engineering Graduate Theses & Dissertations

This thesis provides evidence supporting the claim that weak static and pulsed magnetic fields have measureable effects upon fibrosarcoma cells. Fibroblast and fibrosarcoma cell lines were exposed to 0, 100, and 200μT fields, with a static 45μT field as the control. Each exposure intensity, other than 0μT, was conducted at a 20 sec pulse repetition rate, as well as the normal static conditions. The cells were tested for variations in oxidative stress, membrane potential, and cell viability. The fibrosarcoma cells were also tested for cell count. The trials were conducted using an electromagnetic system that provided a controlled magnetic environment ...
