Stem Cells and Progenitor Cells in Ischemic Stroke - Fashion or Future? by Thorsten R. Doeppner,Dirk M. Hermann Pdf

Stroke remains one of the most devastating diseases in industrialized countries. Recanalization of the occluded arterial vessel using thrombolysis is the only causal therapy available. However, thrombolysis is limited due to severe side effects and a limited time window. As such, only a minority of patients receives this kind of therapy, showing a need for new and innovative treatment strategies. Although neuroprotective drugs have been shown to be beneficial in a variety of experimental stroke models, they ultimately failed in clinical trials. Consequently, recent scientific focus has been put on modulation of post-ischemic neuroregeneration, either via stimulation of endogenous neurogenesis or via application of exogenous stem cells or progenitor cells. Neurogenesis persists within the adult brain of both rodents and primates. As such, neural progenitor cells (NPCs) are found within distinct niches like the subventricular zone (SVZ) of the lateral ventricles and the subgranular zone of the dentate gyrus. Cerebral ischemia stimulates these astrocyte-like progenitor cells, upon which NPCs proliferate and migrate towards the site of lesion. There, NPCs partly differentiate into mature neurons, without significantly being integrated into the residing neural network. Rather, the majority of new-born cells dies within the first weeks post-stroke, leaving post-ischemic neurogenesis a phenomenon of unknown biological significance. Since NPCs do not replace lost brain tissue, beneficial effects observed in some studies after either stimulated or protected neurogenesis are generally contributed to indirect effects of these new-born cells. The precise identification of appropriated cellular mediators, however, is still elusive. How do these mediators work? Are they soluble factors or maybe even vesicular structures emanating from NPCs? What are the cues that guide NPCs towards the ischemic lesion site? How can post-ischemic neurogenesis be stimulated? How can the poor survival of NPCs be increased? In order to support post-ischemic neurogenesis, a variety of research groups have focused on application of exogenous stem/progenitor cells from various tissue sources. Among these, cultivated NPCs from the SVZ and mesenchymal stem cells (MSCs) from the bone marrow are frequently administered after induction of stroke. Although neuroprotection after delivery of stem/progenitor cells has been shown in various experimental stroke models, transplanted cells are usually not integrated in the neural network. Again, the vast amount of grafted cells dies or does not reach its target despite profound neuroprotection, also suggesting indirect paracrine effects as the cause of neuroprotection. Yet, the factors being responsible for these observations are under debate and still have to be addressed. Is there any “optimal” cell type for transplantation? How can the resistance of grafted cells against a non-favorable extracellular milieu be increased? What are the molecules that are vital for interaction between grafted cells and endogenous NPCs? The present research topic seeks to answer - at least in part - some of the aforementioned questions. Although the research topic predominantly focuses on experimental studies (and reviews alike), a current outlook towards clinical relevance is given as well.

Neuroinflammation in Stroke by Ulrich Dirnagl,Bernd Elger Pdf

The successful treatment of acute stroke remains one of the major challenges in clinical medicine. Over the last decades, the understanding of stroke pathophysiology has greatly improved, while the therapeutic options in stroke therapy remain very limited. Today, hyperacute mechanisms of damage, such as excitotoxicity, can be discriminated from delayed ones, such as inflammation and apoptosis. Targeting of inflammation has already been successfully applied in various stroke models, but translation into a clinically efficacious strategy has not been achieved so far. In this book, leading experts in basic cerebrovascular research as well as stroke treatment review the current evidence for and against an important role for inflammation in stroke, and explore the potential of treating or modulating inflammation in stroke therapy.

Adult Neurogenesis by Gerd Kempermann Pdf

The discovery of adult neurogenesis and of stem cells in the brain has changed our view of the mature brain. Though we now know that the adult brain can make new neurons, it normally does so only in two privileged regions, the olfactory bulb and the hippocampus. Yet stem cells, which have the potential to produce new neurons, can be found throughout the adult brain. So why does the brain not make wider use of its potential for neurogenesis? And what is the function of new neurons and of neural stem cells in areas where they occur? After all, the brain regenerates poorly and many neurological and psychiatric disorders are chronic because cell replacement has not taken place. This is the first comprehensive, integrated account of one of the most exciting areas of neuroscience. It begins with the historical background and discusses theories of adult neurogenesis and neural stem cell biology in the context of learning and memory processes as well as structural plasticity. It describes in detail neurogenesis in the adult hippocampus and olfactory system and then surveys the regulatory, functional, and comparative aspects, concluding with a chapter on the provocative hypotheses that link failing adult neurogenesis with such diseases as temporal lobe epilepsy, major depression, brain tumors, and dementias. For graduate students, investigators, and clinicians in the neurosciences, developmental biology, and stem cell research, this book is a unique resource that sifts through the evidence for exciting scientific ideas and fosters a realistic view of the therapeutic possibilities for the use of stem cells in the adult brain.

Molecular Imaging I by Wolfhard Semmler,Markus Schwaiger Pdf

The aim of this textbook of molecular imaging is to provide an up to date review of this rapidly growing field and to discuss basic methodological aspects necessary for the interpretation of experimental and clinical results. Emphasis is placed on the interplay of imaging technology and probe development, since the physical properties of the imaging approach need to be closely linked with the biologic application of the probe (i.e. nanoparticles and microbubbles). Various chemical strategies are discussed and related to the biologic applications. Reporter-gene imaging is being addressed not only in experimental protocols, but also first clinical applications are discussed. Finally, strategies of imaging to characterize apoptosis and angiogenesis are described and discussed in the context of possible clinical translation.

Regenerative Rehabilitation by Sarah M. Greising,Jarrod A. Call Pdf

This contributed volume presents the current state of research on regenerative rehabilitation across a broad range of neuro- and musculoskeletal tissues. At its core, the primary goal of regenerative rehabilitation is to restore function after damage to bones, skeletal muscles, cartilage, ligaments/tendons, or tissues of the central and peripheral nervous systems. The authors describe the physiology of these neuro- and musculoskeletal tissue types and their inherent plasticity. The latter quality is what enables these tissues to adapt to mechanical and/or chemical cues to improve functional capacity. As a result, readers will learn how regenerative rehabilitation exploits that quality, to trigger positive changes in tissue function. Combining basic, translational, and clinical aspects of the topic, the book offers a valuable resource for both scientists and clinicians in the regenerative rehabilitation field.

Mesenchymal Stem Cell Therapy by Lucas G. Chase,Mohan C Vemuri Pdf

Over the past decade, significant efforts have been made to develop stem cell-based therapies for difficult to treat diseases. Multipotent mesenchymal stromal cells, also referred to as mesenchymal stem cells (MSCs), appear to hold great promise in regards to a regenerative cell-based therapy for the treatment of these diseases. Currently, more than 200 clinical trials are underway worldwide exploring the use of MSCs for the treatment of a wide range of disorders including bone, cartilage and tendon damage, myocardial infarction, graft-versus-host disease, Crohn’s disease, diabetes, multiple sclerosis, critical limb ischemia and many others. MSCs were first identified by Friendenstein and colleagues as an adherent stromal cell population within the bone marrow with the ability to form clonogenic colonies in vitro. In regards to the basic biology associated with MSCs, there has been tremendous progress towards understanding this cell population’s phenotype and function from a range of tissue sources. Despite enormous progress and an overall increased understanding of MSCs at the molecular and cellular level, several critical questions remain to be answered in regards to the use of these cells in therapeutic applications. Clinically, both autologous and allogenic approaches for the transplantation of MSCs are being explored. Several of the processing steps needed for the clinical application of MSCs, including isolation from various tissues, scalable in vitro expansion, cell banking, dose preparation, quality control parameters, delivery methods and numerous others are being extensively studied. Despite a significant number of ongoing clinical trials, none of the current therapeutic approaches have, at this point, become a standard of care treatment. Although exceptionally promising, the clinical translation of MSC-based therapies is still a work in progress. The extensive number of ongoing clinical trials is expected to provide a clearer path forward for the realization and implementation of MSCs in regenerative medicine. Towards this end, reviews of current clinical trial results and discussions of relevant topics association with the clinical application of MSCs are compiled in this book from some of the leading researchers in this exciting and rapidly advancing field. Although not absolutely all-inclusive, we hope the chapters within this book can promote and enable a better understanding of the translation of MSCs from bench-to-bedside and inspire researchers to further explore this promising and quickly evolving field.
