This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous work has demonstrated that portal myofibroblasts (PMFs) significantly contributed to liver fibrogenesis and modulated angiogenesis in liver fibrosis. The main aim of this thesis was to elucidate the landscape of portal mesenchymal cells, with a particular focus on a portal mesenchymal stem cell niche. We characterized the murine normal liver portal mesenchymal cell landscape. Importantly, we revealed a portal mesenchymal cell population with the features of mesenchymal stem cells (MSCs), designated portal mesenchymal stem cells (PMSCs) that possessed the ability to give rise to PMFs in vitro. Furthermore, we identified Slit2 as a new marker of PMSCs based on scRNA-seq and bulk RNA-seq analysis. In vivo, we observed PMSC expansion (measured by the expression of Slit2) in liver from both animal fibrosis models (DDC and CDAA) and patients with chronic liver disease (NASH, PSC and other liver disease). Notably, we defined the specific gene signatures for PMSCs and hepatic stellate cells (HSCs), respectively. By using these markers, we provide further evidence indicating that PMSCs expand in correlation with fibrogenesis and angiogenesis in different murine and human liver diseases, whereas the HSCs gene signatures did not vary. In conclusion, our work collectively offers insights into the components and functions of the mammalian liver portal mesenchymal cell populations, and in particular, identify and characterize PMSCs and their derived myofibroblasts, opening up the possibility for the development of novel targeted drugs or biomarkers of clinical significance with increased precision.

Download or read book Liver Myofibroblasts written by Jiri Kanta and published by Frontiers Media SA. This book was released on 2016-10-25 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Myofibroblasts (MFB) are found in most tissues of the body. They have the matrix-producing functions of fibroblasts and contractile properties that are known from smooth muscle cells. Fundamental work of the last decades has shed remarkable light on their origin, biological functions and role in disease. During hepatic injury, they fulfill manifold functions in connective tissue remodeling and wound healing, but overshooting activity of MFB on the other side induces fibrosis and cirrhosis. The present e-book "Liver myofibroblasts" contains 9 articles providing comprehensive information on "hot topics" of MFB. In our opening editorial we provide a short overview of the origin of MFB and their relevance in extracellular matrix formation which is the hallmark of hepatic fibrosis. Thereafter, leading experts in the field share their current perspectives on special topics of (i) MFB in development and disease, ii) their role in hepatic fibrogenesis, and (iii) promising therapies and targets that are suitable to interfere with hepatic fibrosis.

Download or read book Cooperation of Liver Cells in Health and Disease written by Z. Kmiec and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is only during the last decade that the functions of sinusoidal endothelial cells, Kupffer cells, hepatic stellate cells, pit cells and other intrahepatic lymphocytes have been better understood. The development of methods for isolation and co-culturing various types of liver cells has established that they communicate and cooperate via secretion of various intercellular mediators. This monograph summarizes multiple data that suggest the important role of cellular cross-talk for the functions of both normal and diseased liver. Special features of the book include concise presentation of the majority of detailed data in 19 tables. Original schemes allow for the clear illustration of complicated intercellular relationships. This is the first ever presentation of the newly emerging field of liver biology, which is important for hepatic function in health and disease and opens new avenues for therapeutic interventions.

Download or read book Prominin 1 CD133 New Insights on Stem Cancer Stem Cell Biology written by Denis Corbeil and published by Springer Science & Business Media. This book was released on 2012-11-19 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: ​​​​​​​Prominin-1 or otherwise known as CD133 is a glycoprotein that is present in humans and mice. Since the first description of prominin in 1997, in mouse neuroepithelial cells and in human hematopoietic stem cells as AC133 antigen, this molecule has aroused a large interest especially, as a stem cell marker, that gave rise to an ever growing body of publications and more recently its expression in cancer stem cells. Controversies as to its role as a cancer stem and its detection in different models, as well as its use as a prognostic marker have emerged. Yet, beyond its use as a stem cell and cancer stem cell marker, prominin-1/CD133 displays unique biological features and appears of importance in other processes like for example in retinal biogenesis. Indeed, this five-transmembrane plasma membrane glycoprotein, which marks membrane protrusions is associated with several essential processes like cell polarity, asymmetric cell division and membrane remodeling. We propose to review current knowledge about this intriguing molecule and present pertinent information to determine the biological role of prominins and assess their importance in medicine and cancer research. The primary audience for this book is geared towards scientists and researchers with interest in cancer stem cells, stem cells, cell biology, neurobiology, and regenerative medicine.

Download or read book Stem Cell Therapy for Vascular Diseases written by Tulio Pinho Navarro and published by Springer Nature. This book was released on 2020-11-05 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vascular diseases are the leading cause of death worldwide. Distinguished clinical and surgical approaches have attempted to overcome its morbidity and mortality; still 17.9 million people die every year due to vascular affections. Stem cell therapy has emerged as a promising therapeutic strategy. Stem cells synthesize and secrete cytokines that promote cell recruitment, immunomodulation, extracellular matrix remodeling, angiogenesis, and neuroregeneration, all of which promote regeneration. Besides that, stem cells are also capable of differentiating in various cell types, being employed in tissue engineering. Preclinical and clinical investigations have reported efficacy of stem cell therapy for various vascular diseases. Even though results are encouraging, the studies demonstrate variation in stem cell type and origin, route and protocol for administration, and concomitant use of other treatment strategies, impairing easy interpretation of results and clinical application. The purpose of this book is to compile and comprise the current state of the evidence regarding stem cell therapy for each vascular disease, elucidating possible clinical applications. More than an objective guide for readers on the use of this novel treatment strategy, this publication will advocate for stem cell therapy use and development and will be of significant interest to physicians in a wide range of disciplines as well as researchers.
