This book was released on 2023-05-25 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hepatocytes and bile ductular cells possess stem-like potential in restoring liver tissue. This was derived from rat and mouse injury models such as (a) partial hepatectomy by surgery; (b) acute carbon tetrachloride intoxication; © injuries by D-galactosamine (GalN) or by N-nitrosomorpholine (NNM); (d) experimental hepatocarcinogenesis with NNM using different doses. Liver parenchyma was restored by adult hepatocytes after partial hepatectomy as well as after carbon tetrachloride intoxication. Concurrently, hepatocytes resumed synthesis of alpha-1-fetoprotein (AFP) which depended to a high degree on the animal species and strains used in that studies. In contrast to this way of regeneration, liver repair after heavy injuries by agents such as GalN and NNM was initiated by oval cell proliferation deriving from ductular epithelial cells of the canaliculi of HERING (canals of Hering, intrahepatic bile ductules) as sources of endogenous progenitors. Progenitor populations reach levels of differentiation with fetal gene reactivation and significant AFP expression. Proliferating oval cells operated as transit and amplification compartment during liver regeneration. Oval cell proliferation and concurrent AFP synthesis occurred also in the early stages of hepatocarcinogenesis when the carcinogen NNM was applied in toxic doses. The histologic features compared to those seen in GalN intoxication. NNM carcinogenicity was of concern for both oval cells and adult hepatocytes with risks of transformation and malignant development. At the cancer stage, carcinomas either synthesizing AFP or not can be found side by side in the same liver. AFP expression by cancer cells seems to be a special attribute to differentiation stages in carcinogenesis. Clonality, maturation arrest and retro-differentiation feature cells with high autonomy.

Download or read book Stem Cell and Liver Regeneration written by K. Okita and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellular therapy with liver stem cells and their progeny, including bone marrow cells, is a promising new approach that will contribute significantly to the treatment of liver diseases. The existence of the liver stem cell had long been debated, but it is now generally accepted that the liver contains cells with stem-like properties and that these cells can be activated to proliferate and differentiate into mature hepatocytes under certain conditions. There is also a substantial body of evidence to suggest that oval cells are involved in liver regeneration as they differentiate into hepatocytes and biliary cells. This book is a collection of work on stem cell and liver regeneration, initially delivered at the 14th Yamaguchi (Japan) Symposium on Liver Disease. Its nine chapters present the most recent data about basic and clinical research in hepatology in Japan and other countries, providing a valuable resource for researchers and practitioners alike.

Download or read book Liver Stem Cells written by Takahiro Ochiya and published by Humana Press. This book was released on 2011-12-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing evidence suggests that liver stem cells have the capacity to differentiate into parenchymal hepatocytes or into bile ductular cells. These stem cells may be activated to proliferate after severe liver injury or exposure to hepatocarcinogens. Stem cell replacement strategies are being investigated as an alternative approach to liver repair and regeneration. Additionally, stem cell transplantation has been shown to significantly improve liver function and increase survival in experimentally-induced liver-injury models in animals. In Liver Stem Cells: Methods and Protocols, expert researchers focus on several hepatic progenitor cells, hepatic differentiation form stem cells, bile ductal cell formation from stem cells, liver stem cells and hepatocarcinogenesi, and application of liver stem cells for cell therapy. These topics shed light on stem cell technology which may lead to the development of effective clinical modalities for human liver diseases. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Thorough and intuitive, Liver Stem Cells: Methods and Protocols seeks to aid scientists in the further study of preclinical and clinical investigations that explore the therapeutic potential of stem cells in repair of liver injuries.

Download or read book Cystogenesis written by Jong Hoon Park and published by Springer. This book was released on 2016-10-12 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a highly prevalent hereditary renal disorder in which fluid-filled cysts are appeared in both kidneys. Main causative genes of ADPKD are PKD1 and PKD2, encoding for polycystin-1 (PC1) and polycystin-2 (PC2) respectively. Those proteins are localized on primary cilia and function as mechanosensor in response to the fluid flow, translating mechanistic stimuli into calcium signaling. With mutations either of PKD1 or PKD2, hyper-activated renal tubular epithelial cell proliferation is observed, followed by disrupted calcium homeostasis and aberrant intracellular cyclic AMP (cAMP) accumulation. Increased cell proliferation with fluid secretion leads to the development of thousands of epithelial-lined, fluid-filled cysts in kidneys. It is also accompanied by interstitial inflammation, fibrosis, and finally reaching end-stage renal disease (ESRD). In human ADPKD, the age at which renal failure typically occurs is later in life, however no specific targeted medications are available to cure ADPKD. Recently, potential therapeutic targets or surrogate diagnostic biomarkers for ADPKD are proposed with the advances in the understanding of ADPKD pathogenesis, and some of them were attempted for clinical trials. Herein, we will summarize genetic and epi-genetic molecular mechanisms in ADPKD progression, and overview the currently available biomarkers or potential therapeutic reagents suggested.
Download or read book Stem Cells Regenerative Medicine written by Krishnarao Appasani and published by Springer Science & Business Media. This book was released on 2010-11-01 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Defined as, “The science about the development of an embryo from the fertilization of the ovum to the fetus stage,” embryology has been a mainstay at universities throughout the world for many years. Throughout the last century, embryology became overshadowed by experimental-based genetics and cell biology, transforming the field into developmental biology, which replaced embryology in Biology departments in many universities. Major contributions in this young century in the fields of molecular biology, biochemistry and genomics were integrated with both embryology and developmental biology to provide an understanding of the molecular portrait of a “development cell.” That new integrated approach is known as stem-cell biology; it is an understanding of the embryology and development together at the molecular level using engineering, imaging and cell culture principles, and it is at the heart of this seminal book. Stem Cells and Regenerative Medicine: From Molecular Embryology to Tissue Engineering is completely devoted to the basic developmental, cellular and molecular biological aspects of stem cells as well as their clinical applications in tissue engineering and regenerative medicine. It focuses on the basic biology of embryonic and cancer cells plus their key involvement in self-renewal, muscle repair, epigenetic processes, and therapeutic applications. In addition, it covers other key relevant topics such as nuclear reprogramming induced pluripotency and stem cell culture techniques using novel biomaterials. A thorough introduction to stem-cell biology, this reference is aimed at graduate students, post-docs, and professors as well as executives and scientists in biotech and pharmaceutical companies.

Value-neutral education and counseling for persons considering testing. Use of test results in insurance, employment, and other settings.
Download or read book Hepatocyte Transplantation written by S. Gupta and published by Springer Science & Business Media. This book was released on 2002-09-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been an increasing need for transplantation, but the number of donor livers available has increased only slightly, despite intensive public relations activities. New concepts in the field of transplantation, for instance the transplantation of living donor organs or the splitting of organs, are urgently required, to safeguard the treatment of patients with severe liver disease. The development and clinical application of cell therapy for patients with liver disease could soon present a significant enhancement of the therapeutic options. The aim of such cell therapy is to repair or improve the biological function of the chronically and acutely damaged liver. Even though systematic trials are not available, individual case reports and small series already show promising clinical results. Present concepts of cell therapy for liver diseases based on the use of primary hepatocytes have recently been considerably extended through new data on the biology of stem cells. The adult haematopoetic stem cell as a pool for hepatocyte grafts - what would be the perspectives for the clinical application? This book is the proceedings of the Falk Symposium No. 126 on `Hepatocyte Transplantation' (Progress in Gastroenterology and Hepatology Part III) held in Hannover, Germany, October 2-3, 2001, and is a forum for basic research, but also for questions concerning clinical applications in the field of hepatocyte transplantation.
Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Download or read book Pediatric Hepatology and Liver Transplantation written by Lorenzo D'Antiga and published by Springer. This book was released on 2019-04-29 with total page 829 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first to provide balanced examination of both pediatric liver disease and liver transplantation – two topics that are inherently related, given that most chronic liver disorders eventually require organ replacement. The different forms of liver disease encountered in the pediatric age group are first discussed in a series of disease-specific chapters that have a reader-friendly, uniform structure covering pathophysiology, diagnostic and treatment algorithms, clinical cases, and transition to adult care. Key topics in the field of liver transplantation are then addressed. Examples include indications and contraindications, surgical techniques and complications, immunosuppression, in pediatric liver transplantation, acute and chronic rejection and allograft dysfunction, and CMV and EBV infection in transplant recipients, long-term graft injury and tolerance. A section on pediatric hepatology across the world includes chapters presenting the features and management of pediatric liver disease in South-America, Africa and Asia. A closing section considers what the future holds for pediatric liver disease and its management, including novel genetic testing, cell therapy and gene therapy. Pediatric Hepatology and Liver Transplantation will be of value for a range of practitioners, from residents making their first approach to pediatric liver disease through to specialists working in transplantation centers.
