Creep Response And Adhesion Dynamics Of Glioblastoma Multiforme Cells During Migration In Confined Environment, Ishan Kamal Khan
Creep Response And Adhesion Dynamics Of Glioblastoma Multiforme Cells During Migration In Confined Environment, Ishan Kamal Khan
Bioengineering Dissertations
Glioblastoma multiforme (GBM) is the most common and malignant form of primary brain tumor. One of the major challenges facing the treatment of GBM tumors is the detachment and subsequent migration of peripheral cells. Migration of GBM cells take place in mechanically distinct confined microenvironment along the borders of white matter tracts. Studies using microfluidic devices mimicking the in-vivo microenvironment have shown that the migration characteristics are significantly altered with the change in kinematic state of the migrating cell. Several studies on different types of cells have consistently shown that a cancerous cell is more compliant than a normal cell …
Developing A 3d In Vitro Model By Microfluidics, Hung-Ta Chien
Developing A 3d In Vitro Model By Microfluidics, Hung-Ta Chien
Dissertations and Theses
In vitro tissue models play an important role in providing a platform that mimics the realistic tissue microenvironment for stimulating and characterizing the cellular behavior. In particular, the hydrogel-based 3D in vitro models allow the cells to grow and interact with their surroundings in all directions, thus better mimicking in vivo than their 2D counterparts. The objective of this thesis is to establish a 3D in vitro model that mimics the anatomical and functional complexity of the realistic cancer microenvironment for conveniently studying the transport coupling in porous tissue structures. We pack uniform-sized PEGDA-GelMA microgels in a microfluidic chip to …
Creation Of A 3d Construct To Aid Cell Migration And Promote Cell Capture, Joseph Michael Sanders
Creation Of A 3d Construct To Aid Cell Migration And Promote Cell Capture, Joseph Michael Sanders
Legacy Theses & Dissertations (2009 - 2024)
Most cancer-related deaths are attributed to metastasis. The tumor microenvironment is a complex environment which is not fully understood. The Nano Intravital Device (NANIVID) is a versatile, biocompatible device that allows for the manipulation of the tumor microenvironment in vitro and in vivo, providing a platform to study various aspects of tumor progression. The purpose of this study is to modify the NANIVID to resemble the tumor microenvironment in order to allow for a seamless transition from the in vivo environment into the engineered environment within the NANIVID. This engineered microenvironment will promote cell migration and cell capture. It has …
The Mechanotransduction Of Primary Cilia In Tumor Progression Of Lung Adenocarcinoma, Sagar Patel
The Mechanotransduction Of Primary Cilia In Tumor Progression Of Lung Adenocarcinoma, Sagar Patel
Theses and Dissertations
The objective of this study was to investigate primary cilia and their mechanotransduction role in lung adenocarcinoma tumor progression. The main focus investigated the effect of primary cilia on cell cycle progression, survival, adhesion and migration analysis of these cells and the role of sonic hedgehog signaling pathway in mechanotransduction. Human Non-Small Cell Lung Cancer (NSCLC) adenocarcinoma biopsies contain more primary cilia than non-tumor lung sections. To observe the effects of primary cilia presence in lung cancer cells in-vitro, formation of primary cilia is inhibited using small interfering RNA. A549 cells with intact primary cilia observe less cell cycle progression …
