Lung Stem Cells in the Epithelium and Vasculature


Book Description

This book covers the identification and role of endogenous lung stem cells in health and disease, particularly the most recent advances. In addition, it discusses the rapidly growing field of stem cells and cell therapy as it relates to lung biology and disease as well as ex vivo lung bioengineering. Such approaches may provide novel therapeutic approaches for lung diseases. Human pluripotent stem cell differentiation to model the pulmonary epithelium and vasculature is also discussed. World-recognized scientists who specialize in studying both the lung epithelium and pulmonary vasculature contribute the chapters. Topics covered include: stem cell niches in the lung, the role of progenitor cells in fibrosis and asthma, iPSC in modeling lung disease, vascular repair by endothelial progenitor cells and circulating fibrocytes in pulmonary vascular remodeling. This volume of the Stem Cell Biology and Regenerative Medicine series is essential reading for researchers and clinicians interested in stem cells, lung biology and regenerative medicine. It is also an invaluable resource for advanced students studying cell biology, regenerative medicine and lung physiology.




Stem Cells in the Respiratory System


Book Description

In this state-of-the-art exploration of a hugely dynamic and fast-evolving field of research, leading researchers share their collective wisdom on the role that stem cells could play in the context of physiological stress and lung injury. The text focuses on reviewing the most relevant—and recent—ideas on using local, endogenous, and exogenous progenitor/stem cells in preventing and treating injury to the lung. The lungs are one of the most complex organs in the human body, with a mature adult lung boasting at least 40 morphologically differentiated cell lineages. Our entire blood supply passes through the lung’s alveolar units during oxygenation. This interaction with the outside world, along with the intricacies of its structure, makes the lung a highly susceptible organ that is vulnerable to numerous types of injury and infection. This means that the mechanisms of lung repair are in themselves correspondingly complex. Because of their multipotentiality, as well as the fact of the lung’s relatively rapid cell turnover, stem cells are thought to be an important alternative cell-base therapy in lung injury. Despite the controversial nature of stem cell research, there has been growing interest in both local and endogenous stem cells in the lung. This highly topical book with chapters on everything from using mesenchymal stem cells in lung repair to the effect of physical activity on the mobilization of stem and progenitor cells, represents an exciting body of work by outstanding investigators and will be required reading for those with an interest in the subject.




Stem Cell Research Progress


Book Description

There are two broad categories of mammalian stem cells: embryonic stem cells, derived from blastocysts, and adult stem cells, which are found in adult tissues. This text presents research from around the globe in this dynamic field.




Lung Stem Cells in Development, Health and Disease


Book Description

Most organs in the adult human body are able to maintain themselves and undergo repair after injury; these processes are largely dependent on stem cells. In this Monograph, the Guest Editors bring together leading authors in the field to provide information about the different classes of stem cells present both in the developing and adult lung: where they are found, how they function in homeostasis and pathologic conditions, the mechanisms that regulate their behaviour, and how they may be harnessed for therapeutic purposes. The book focuses on stem cells in the mouse and human lung but also includes the ferret as an increasingly important new model organism. Chapters also discuss how lung tissue, including endogenous stem cells, can be generated in vitro from pluripotent stem cell lines. This state-of-the-art collection comprehensively covers one of the most exciting areas of respiratory science




Stem Cells


Book Description

Beginning with a basic introduction to the field, this book provides a comprehensive review of the properties and potential uses of stem cells, including stem cells in tissue engineering, cancer, gene therapy and in dental tissues. Stem Cells compares two key types of mammalian stem cell - embryonic and adult. Different stem cell systems are discussed, as well as potential obstacles in the use of human stem cells.




Fetal and Neonatal Lung Development


Book Description

Lung disease affects more than 600 million people worldwide. While some of these lung diseases have an obvious developmental component, there is growing appreciation that processes and pathways critical for normal lung development are also important for postnatal tissue homeostasis and are dysregulated in lung disease. This book provides an authoritative review of fetal and neonatal lung development and is designed to provide a diverse group of scientists, spanning the basic to clinical research spectrum, with the latest developments on the cellular and molecular mechanisms of normal lung development and injury-repair processes, and how they are dysregulated in disease. The book covers genetics, omics, and systems biology as well as new imaging techniques that are transforming studies of lung development. The reader will learn where the field of lung development has been, where it is presently, and where it is going in order to improve outcomes for patients with common and rare lung diseases.




Stem Cells and Regenerative Medicine


Book Description

The commercialization of biotechnology has resulted in an intensive search for new biological resources for the purposes of increasing food productivity, medicinal applications, energy production, and various other applications. Although biotechnology has produced many benefits for humanity, the exploitation of the planet's natural resources has also resulted in some undesirable consequences such as diminished species biodiversity, climate change, environmental contamination, and intellectual property right and patent concerns.This book discusses the role of biological, ecological, environmental, ethical, and economic issues in the interaction between biotechnology and biodiversity, using different contexts. No other book has discussed all of these issues in a comprehensive manner. Of special interest is their impact when biotechnology is shared between developed and developing countries, and the lack of recognition of the rights of indigenous populations and traditional farmers in developing countries by large multinational corporations.




Bone Marrow Stem Cell-mediated Airway Epithelial Regeneration


Book Description

It has been suggested that some adult bone marrow cells (BMC) can localize to the injured tissues and develop tissue-specific characteristics including those of the pulmonary epithelium. In Chapter 2 we show that the combination of mild airway injury as a conditioning regimen to direct the site of BMC localization and transtracheal delivery of short-term cultured BMC enhances airway localization and adoption of an epithelial-like phenotype expressing Clara cell secretory protein (CCSP) and pro-surfactant protein-C. Bone marrow cells from transgenic mice expressing green fluorescent protein driven by the epithelial-specific cytokeratin-18 promoter were injected transtracheally into airway-injured wild-type recipients. BMC retention in the lung was observed to be at least 120 days following cell delivery with increasing transgene expression over time. The results indicate that targeted delivery of BMC can promote airway regeneration.In Chapter 4 we enrich for a stem/progenitor cell population within the CCSP+ using the stem cell antigen (Sca)-1 as a marker. Here we identified a putative epithelial stem/progenitor cell that can be induced to differentiate into various lung epithelial cell lineages expressing markers exclusive to airway or alveolar epithelial cells when cultured under an air liquid interface. These cells also have self-renewal potential in vitro that can proliferate in vivo and repopulate the injured airway epithelium. This newly discovered epithelial-like cells may play a central role in the bone marrow contribution to lung repair and are exciting candidates for cell-based targeted therapy for treatment of lung diseases.Although bone marrow stem/progenitor cells can develop into lung epithelial cells, the specific subpopulation remains unknown. In Chapter 3 we identify a newly discovered population of murine and human BMC that express CCSP. These CCSP+ cells increase in the bone marrow and blood after airway injury and can be expanded in culture. CCSP+ cells are unique in that they express both hematopoietic and mesenchymal stromal cell markers and can give rise to various lung epithelial lineages in vitro. Importantly, bone marrow transplant of CCSP+ cells to CCSP knockout recipients confirms that bone marrow CCSP+ cells contribute to airway epithelium after airway injury.
