This book was released on 2014 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microfabrication and microfluidic devices have been recognized as potential platforms for cell-based and drug screening studies. Human glioblastoma multiforme (hGBM) cells migrate inside the central nervous system (CNS) in narrow space constrictions and rarely metastasize through bloodstream. Hence, microfluidic devices consisting of narrow channels are considered as suitable models to study cell migration in vitro. Further the migratory capability of each individual cell could be easily obtained and quantified using such system. This effort presents the design and development of an alternative microfluidic system that provides an integrated array of channels for screening multiple drugs simultaneously. This system is an altered version of traditional system, where a single unit is replaced with multiple units to achieve high-throughput multi-screening platform. The device is tailored to screen various types and doses of drugs simultaneously thus increasing its efficiency. This design has the advantage of using multiple types of drugs of varying concentrations to simultaneously study their effectiveness to inhibit cancer cell migration. Using this platform the migration characteristics of cancer cells in response to various anti-cancer drugs is investigated as part of this research effort. Also, the therapeutic potential of anti-cancer drugs were evaluated quantitatively, in comparison with standard cancer migration (scratch wound) assay.

Download or read book Microfluidic Platform for Capturing Circulating Tumor Cells from Whole Blood written by Sweta Gupta and published by . This book was released on 2011 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viable tumor cells that are disseminated in the blood stream, also known as circulating tumor cells (CTCs), are often the cause of metastasis in cancer patients. Although these cells are rare in blood, they can be isolated and used to study various aspects of the tumor such as molecular characterization of the tumor cells, effectiveness of treatment therapies in metastatic carcinoma patients, and also to determine the primary site of the tumor in cases where the tumor itself is undetectable. Previous researches have demonstrated microfluidic platforms capable of selectively capturing rare cells from raw liquid samples, using adhesion-mediated binding of the target cells with complementary ligand proteins that are immobilized on arrays of micropillars. In these systems, the circular or square shaped micropillars which provide increased surface area for cell-protein interactions, were fabricated on a silicon chip by an expensive and skillfully demanding technique called deep reactive ion etching (DRIE) [1,2]. Based on the concept of protein-coated micropillars, we used soft lithographic techniques to develop microfluidic devices using poly(dimethylsiloxane) (PDMS) polymer. PDMS molds consisting of thirty five different device designs with varied micropillar features like shape, size, spacing, and array arrangement were fabricated. The devices were tested with five different cancer cell lines, at different flow rates and cell concentrations, and a comparative study was performed to determine the most efficient design in terms of cell capture efficiency. Some designs achieved mean capture yields of>45%, thereby making this low-cost, quick and easy technique an attractive cancer screening tool.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the world, cancer is a primary health concern due its high mortality rate. The typical cause of death from cancer is metastasis, which is the spreading of a primary tumor to distant organs. Currently, cancer metastasis is attributed to Circulating Tumor Cells (CTCs). A CTC is a cancer cell that has dislodged from the primary tumor and entered the blood stream. In order to achieve early cancer detection and improve patient prognosis, CTCs must be separated from whole blood samples. One of the most promising ways to achieve this separation is through microfluidic devices. Unfortunately, experimental testing of microfluidic devices is expensive, time-consuming, and lacks the ability to demonstrate underlying physics. To help resolve the issues associated with experimental testing, numerical modeling is employed. Here, two types of label-free microfluidic devices are modeled and tested. First, a microfiltration device is modeled and the effects of a non-axisymmetric approach are tested. From the results, critical pressure was found to be a robust design criterion for microfiltration devices regardless of CTC approach condition. CTC transit time on the other hand was determined to have a dependence on approach condition; therefore, should not be used in designing microfiltration devices. The other type of label-free microfiltration device tested was a Deterministic Lateral Displacement (DLD) device. Here, underlying causes of experimental observations for a symmetric airfoil shaped pillar design were achieved through numerical modeling of flow fields and array anisotropy. Results show that array anisotropy is responsible for creating a lateral shift in the flow field. Critical size of the DLD device is reduced when the flow field shifts toward the direction of bumped motion, and increases when shifting occurs away from bumped motion. Additionally, an equation is proposed that relates migration angle to anisotropy via pseudoperiodicity. Lastly, a working limit for symmetric airfoil shaped pillar DLD devices was found to be between -25° and -35° angle of attack. These findings will aid in future design work and open the possibility of new applications for micro fabricated DLD devices by achieving smaller critical sizes than previously possible.

Download or read book Separation of Circulating Tumor Cells Using Deformation based Microfluidic Devices written by Hashem Mohammad Abul and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Circulating Tumor Cells (CTCs) are potential indicators of cancer. Detection of CTCs is important for diagnosing cancer at an early stage and predicting the effectiveness of cancer treatment. Recent progress in the development of microfluidic chips has inaugurated a new possibility for designing diagnostic devices for early cancer detection. Among various devices, deformation-based CTC microchips have shown a strong promise for CTC detection due to its simplicity and low cost. This type of devices involves a process where CTCs are trapped while allowing more deformable blood cells to squeeze through the filtration geometry at the specified operating pressure. Fundamental understanding of CTC passing event through a micro-filtering channel seems to be a promising direction in studying these microdevicessince it helps optimize the microfilter design for achieving high isolation purity and capture efficiency. Along with the experimental studies, numerical simulation emerges as a powerful tool to predict the behavior of a cell inside a microfilter, and may deliver important insights to optimize the processes by saving time and cost. First, the CTC squeezing process through a microfluidic filtering channel is studied by modeling the CTC as a simple liquid droplet. Cell modeling employed both Newtonian and non-Newtonian approaches to simplify the model and investigating different biophysical properties. Detailed microscopic multiphase flow characteristics regarding the filtering process are discussed including the pressure signatures, flow details, and cell deformation. Next, we employed a compound droplet model consisting of an outer cell membrane, cytoplasm and the nucleus to study the flow dynamics more realistically. The effects of different parameters such as the nuclear to cytoplasmic size ratio (N/C), operating flow rate and viscosity of the cell has been investigated. We studied critical pressure for the CTC at different flow rates as it plays a crucial role in the device operation in ensuring a successful passing event. Our study provides an insight into the cell squeezing process and its characteristics, which can guide in the design and optimization of next-generation deformation-based CTC microfilters.
