Available in PDF, EPUB and Kindle. Book excerpt: Cells secrete various biomolecules, including cytokines or growth factors and enzymes, to mediate cellular behavior and cell-cell signaling in the immune system, tumor microenvironment, or stem cell niche. It is essential to analyze cell-secreted products to understand how cells response to external stimuli, which may provide us valuable information and knowledge related to basic cell biology, disease diagnosis and therapeutics. This dissertation describes the development of microfluidic-based cell culture microsystems with integrated biosensors for monitoring of cellular secretory activities in real-time, which aims at better understanding of cancer cellular signaling to mediate the extracellular matrix in cancer cell invasion and metastasis, cellular inflammatory response upon mitogenic stimulation, and autocrine signaling via multiple growth factor release. Various approaches, such as utilization of 3D hydrogel matrix for incorporating sensing elements or application of antibody-conjugated microbeads, were used to enhance the sensitivity of microsystems, which enables to detect low abundant cell-secreted molecules not only from a small group of cells but also from individual cells. Single cell studies revealed the presence of heterogeneous secretion levels of protease, cytokines and exosomes from individual cells, which may not be accessible using population-averaged assays. With a photo-initiated selective cell retrieval method, further in-depth molecular biology analyses are also achievable. Consequently, simultaneous detection of growth factors released from primary hepatocytes was demonstrated using hydrogel-incorporating microsystems for maintaining cellular phenotypes and functions similar to in vivo.

Download or read book Microfluidics for Quantitative Analysis of Cellular and Intercellular Interactions written by Timothy Kwa and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of microfluidics has grown steadily over the last decade and a half, due in part to the large variety of applications for manipulating fluids in nanoliter volumes. Specifically for biomedical engineering, microfluidics has been employed for creating small, well-controlled microenvironments for reliable analysis of small populations of cells. Thus, a thoughtfully designed microfluidic device can be extremely powerful toward assaying various cell functions, including the analysis of the cellular secretome. The focus of this thesis involves creating precisely engineered microfluidic devices to analyze small cell populations contained within carefully considered geometries. By integrating biosensors (electrochemical and optical) with these cellular microenvironments, we can achieve near real-time quantitative analysis of cell-secreted products in response to external stimuli. Combined with computational modeling techniques, we can calculate secretion rates for these products. Moreover, these microenvironments can also serve protective functions and toggle cellular communication, yielding novel information and insights into cellular responses. Through series of experiments such as these, we can develop novel methods for addressing and manipulating cell performance, especially in the context of disease or cellular dysfunction. My work involved microfluidic device design, prototyping, fabrication, and testing to obtain meaningful, quantitative results based on cellular function. Chapter 2 describes a microfluidic device capable of detecting two pro-inflammatory cytokines from cells. In Chapter 3, a reconfigurable microfluidic device was designed to protect cells while regenerating a sensor surface. Chapter 4 describes a microfluidic co-culture of liver cells, monitoring the paracrine interactions between hepatocytes and stellate cells. Chapter 5 reports on the detection of cell-secreted cytokines, analyzed in a reconfigurable device facilitating intercellular communication. In chapter 6, a microfluidic device with integrated valves was designed to assay cellular response to a predictably evolving chemical gradient. These devices with their disparate applications have produced a variety of interesting results pertaining to cellular function and intercellular communication. To this end, future work may be useful for shedding insights into disease pathogenesis and treatment, especially in terms of quantifying dose-dependent responses.

A novel cell sorting device integrated homogenous porous PDMS membrane was invented to classify cells from real samples based on the size difference. The nominee further studied the signal transmission between different cells, and the signal chemicals were qualitative and quantitative monitored by the analysis platform. This indicates the potential significant application of the new cell analysis platform in medicine screening and early diagnosis.

Download or read book Microfluidic Platform for Multi parameter Analysis of Live Single Cells written by Meryl Rodrigues and published by . This book was released on 2014 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellular heterogeneity is a key factor in various cellular processes as well as in disease development, especially associated with immune response and cancer progression. Cell-to-cell variability is considered to be one of the major obstacles in early detection and successful treatment of cancer. Most present technologies are based on bulk cell analysis, which results in averaging out the results acquired from a group of cells and hence missing important information about individual cells and their behavior. Understanding the cellular behavior at the single-cell level can help in obtaining a complete profile of the cell and to get a more in-depth knowledge of cellular processes. For example, measuring transmembrane fluxes oxygen can provide a direct readout of the cell metabolism. The goal of this thesis is to design, optimize and implement a device that can measure the oxygen consumption rate (OCR) of live single cells. A microfluidic device has been designed with the ability to rapidly seal and unseal microchambers containing individual cells and an extracellular optical oxygen sensor for measuring the OCR of live single cells. The device consists of two parts, one with the sensor in microwells (top half) and the other with channels and cells trapped in Pachinko-type micro-traps (bottom half). When the two parts of the device are placed together the wells enclose each cell. Oil is flown in through the channels of the device to produce isolated and sealed microchamber around each cell. Different fluids can be flowed in and out of the device, alternating with oil, to rapidly switch between sealed and unsealed microenvironment around each cell. A fluorescent ratiometric dual pH and oxygen sensor is placed in each well. The thesis focuses on measuring changes in the oxygen consumption rate of each cell within a well. Live and dead cells are identified using a fluorescent live/dead cell assay. Finally, the technology is designed to be scalable for high-throughput applications by controlling the flow rate of the system and increasing the cell array density.
