Book excerpt: "Introduction: In breast cancer (BC), metastasis is the major determinant of poor outcome, a highly organized, non-random and organ selective process. Most patients undergo surgery and also receive other treatments (hormone therapy, radiation or chemotherapy) before or after surgery. Drug resistance and tumor relapse are the main potential problems. Metastasis seeds may be already present at diagnosis as isolated tumor cells within lymph nodes, bone marrow or in the peripheral circulation as circulating tumor cells (CTCs). CTCs hence, are released together with circulating tumor DNA (ctDNA) to the peripheral blood circulation. The current challenge is the collection and characterization of CTCs and the more important subtype, cancer stem cell-like cells (CSCs).Objective: The main objective of this study was to use and study CTCs heterogeneity using a specific methodology for isolation, characterization, and molecular analysis.Methodology: Whole blood apheresis was used for isolation and enrichment. To analyze CTCs heterogeneity flow cytometry (FCM) was used with specific antibodies for the desired markers and then create and optimize platforms for CTCs identification. Subsequently, EpCAM positive CTCs and EpCAM negative CSCs subpopulations were isolated and collected with a technology using immunomagnetic particles coated with EpCAM mononuclear antibody. Finally, flow cytometry was used to compare the EpCAM positive (CTCs) and negative (CSCs) cell populations isolated from breast cancer patients.Results:We successfully collected and isolated CTCs from 20 patients with breast cancer, representing all different subtypes. There was a much higher concentration and quantity of CD45(-) in patients compared to healthy controls. Gating CD45(-) cells, we also noted that patients had a higher count of EpCAM(+)cells. Two patients had EPCAM (-) CD24 (+) cells compared to healthy control which have been reported as CSC-like features. In addition , it was noted that most patients also exhibited a population not seen in healthy individuals where cells expressed both CD24(+) and CD44(+) cell surface markers.Conclusion: Overall, our new methodology was successful in characterizing patient-specific EpCAM negative and positive CTCs indicative of heterogeneity. Our proposed platform is, to our knowledge, unique and at present the only one capable of examining in detail these rare populations particularly the EpCAM negative CSCs subpopulation. Current knowledge indicates that CSCs should be the prime target for therapeutic intervention and development of new drugs or drug combination. Future studies will incorporate further characterization of CTCs"--

Download or read book Microscale Acoustofluidics written by Thomas Laurell and published by Royal Society of Chemistry. This book was released on 2014-12-08 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: The manipulation of cells and microparticles within microfluidic systems using external forces is valuable for many microscale analytical and bioanalytical applications. Acoustofluidics is the ultrasound-based external forcing of microparticles with microfluidic systems. It has gained much interest because it allows for the simple label-free separation of microparticles based on their mechanical properties without affecting the microparticles themselves. Microscale Acoustofluidics provides an introduction to the field providing the background to the fundamental physics including chapters on governing equations in microfluidics and perturbation theory and ultrasound resonances, acoustic radiation force on small particles, continuum mechanics for ultrasonic particle manipulation, and piezoelectricity and application to the excitation of acoustic fields for ultrasonic particle manipulation. The book also provides information on the design and characterization of ultrasonic particle manipulation devices as well as applications in acoustic trapping and immunoassays. Written by leading experts in the field, the book will appeal to postgraduate students and researchers interested in microfluidics and lab-on-a-chip applications.

Download or read book Tumor Invasion and Metastasis written by L.A. Liotta and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: The clinical significance of tumor spread has always been appreciated. Yet, in spite of the pioneering work and outstanding contributions of investigators such as D. Coman, H. Green, B. Fisher, S. Wood and I. Zeidman, studies on metastasis rarely achieved the popularity afforded to more esoteric areas of tumor biology. Tumor dissemination, occurring as it does in a responding host and being composed of a series of dynamic int~ractions, is a highly complex phenomenon. Few investigators were brave enough to attempt to unravel the mechanisms involved. Paradoxically, this very complexity may have contributed, in part, to the recent upsurge of interest in metastasis research. More and more researchers are becoming fascinated by the complexities of the cellular interactions involved in tumor spread. Accompanying this intellectual stimulation have been technological advances in related fields which allow the derivation of new model systems. The mechanisms of metastatic spread are increasingly amenable to both the reductionist and holistic approaches and it is the purpose of this volume to present many of these model systems while emphasizing the intricacy and complexity of the processes they mimic. We have attempted to emphasize two topics not previously covered in depth in previous books on metastases. These are in vitro models of invasion and in teractions of tumor cells with connective tissue.
