Regenerative Nephrology

Progression of chronic diseases in general and chronic kidney disease in particular has been traditionally viewed in the light of various contributors to development of glomerulosclerosis and tubulointerstitial scarring culminating in renal fibrosis. Indeed, this dogma prevailed for decades underscoring experimental attempts to halt fibrotic processes. Breakthrough investigations of the past few years on stem/progenitor cell involvement in organ regeneration caused a conceptual shift in tackling the mechanisms of nephrosclerosis. It has become clear that the rate of progression of chronic kidney disease is the net sum of the opposing trends: degenerative fibrotic processes and regenerative repair mechanisms. The latter part of this equation has been by and large ignored for years and only recently attracted investigative attention. This book revisits the problem of kidney disease by focusing on regenerative mechanisms in renal repair and on the ways these regenerative processes can become subverted by an intrinsic disease process eventuating in its progression. Cutting-edge investigations are summarized by the most experienced international team of experts. Presents a comprehensive, translational source for all aspects of renal stem cells, tissue regeneration, and stem cell therapies for renal diseases in one reference work. This will ultimately result in time savings for academic, medical and pharma researchers Experts in the renal stem cell system in kidney repair and regeneration take readers from the bench research to new therapeutic approaches, providing a common language for nephrology researchers, fellows and other stem cell researchers. This enables the discussion of development of stem cells and their use in the repair and regeneration of the kidney

Since the publication of the first edition of this book in 2010, an explosion of spectacular discoveries in the field of regeneration has compelled the current revisit of the field of Regenerative Nephrology. This second edition features subjects as diverse as age and gender influencing regenerative processes; mechanisms and pathways of premature cell senescence affecting kidney regeneration; the ways intrinsic regenerative processes can become subverted by noxious stressors eventuating in disease progression; novel mechanistic and engineering efforts to recreate functional kidney or its component parts; cell reprogramming and reconditioning as emerging tools of future regenerative efforts; and effects of various biologicals on kidney regeneration. These newer additions to the armamentarium of Regenerative Medicine and Nephrology have become an integral part of the second edition of the book. Cutting-edge investigations are summarized by the constellation of the most experienced contributing authors coming together from around the world under the umbrella of the second edition. A significant expansion of section on induced pluripotent cells and trajectories of their differentiation. This will be followed by mechanisms and modalities of cell reprogramming for therapeutic purposes A new section on tissue engineering of the kidney of interest to nephrologists and urologists An entire section dedicated to causes of regenerative failure with the emphasis on recent discoveries of senescent cells in kidney disease, pathologic effects of senescent cells, advents in senotherapies and rejuvenation therapies A vastly expanded section on pharmacotherapies promoting kidney regeneration, trials of engineered organs, manufacturing in regenerative medicine and smooth transition to the clinical trials, with an update on some ethical issues

Kidney Development, Disease, Repair and Regeneration focuses on the molecular and cellular basis of kidney development, exploring the origins of kidney lineages, the development of kidney tissue subcompartments, as well as the genetic and environmental regulation of kidney development. Special coverage is given to kidney stem cells and possible steps towards kidney repair and regeneration. Emphasis is placed on the fetal origins of postnatal renal disease and our current understanding of the molecular basis of damage and repair. Biomedical researchers across experimental nephrology and developmental biology will find this a key reference for learning how the underlying developmental mechanisms of the kidney will lead to greater advances in regenerative medicine within nephrology. Offers researchers a single comprehensive resource written by leaders from both the developmental biology and the experimental nephrology communities Focuses on understanding the molecular basis of organogenesis in the kidney as well as how this can be affected both genetically and environmentally Explains the underlying developmental mechanisms which influence the kidney’s inherent repair capacity Demonstrates how a deeper understanding of mechanisms will lead to greater advances in regenerative medicine

Regenerative medicine – stem cell and gene-based therapy – offers a new approach for restoring function of damaged organs and tissues. This is the first book to cover the major new aspects and field of regenerative medicine. This title is therefore a timely addition to the literature. It brings together the major approaches to regenerative medicine in one text, which ensures that techniques learnt in one discipline are disseminated across other areas of medicine.

The information given in this book tries to capture the essence of the sheer dynamicity of the cell along with useful tips on how to address critical rate limiting steps in the process of exploration and investigation of its capacity to regenerate, rebuild and replenish from within. The definitions of stem cells, stemness, and the niche concept continue to undergo revisions. In adult vertebrates, hematopoietic and some non-hematopoietic progenitors are synthesized within specialized niches of bone marrow. They migrate to designated tissues, and are either trans-differentiated or become quiescent and settle down. These form the stem cell niche reservoir in all tissues. Not only the primary hematopoietic tissue but all organs and tissues are also capable of generating progenitors which are either synthesized from these migrants or are direct recruits from other tissues. In the niches, the cells settle down and await their turn to either make more clones like themselves or differentiate and mobilize in an exigency. Thus progenitors are important reserves, to be multiplied and deployed or travel as important message bearing molecules via blood as circulating progenitors which can home to their allocated destinations. Upon reaching, specific integrins and selectins help them “dock” and “port” and they may be reprogrammed to induce further differentiation and help repopulate the denuded tissue. In pulmonary fibrosis and asthma, progenitors from both systemic circulation and local stem cell niches have been found to participate in the myriad ramifications of repair, replacement and regeneration of lost or diseased tissue. Whether they are lung specific or global in origin and role remain to be explored. Research tools, fundamental concepts, techniques, methodologies and standard operating protocols and animal models and human extrapolations, have been discussed in a concise way along with detailed description and discussion on the appropriate rationale to introduce the subject to the casual reader and provide valuable tactical information to the specialist in Regenerative Medicine. I sincerely hope you enjoy the work and appreciate the hard work that has gone into designing and executing elegant experiments by many researchers in the field. The branch is multi-disciplinary and I hope that the readers will not be limited to biologists alone.

Kidney Transplantation, Bioengineering, and Regeneration: Kidney Transplantation in the Regenerative Medicine Era investigates how the field of regenerative medicine is changing the traditional premises of solid organ transplantation, specifically within the field of kidney transplantation. In Section 1, chapters illustrate the state of the art in kidney transplantation as well as the research behind the bioengineering and regeneration of kidney organoids for therapeutic renal replacement. In Section II, chapters catalog the technologies that are being developed and the methods that are being implemented to bioengineer or regenerate kidneys in order to restore function, while critically highlighting those technological advances which hold the most promise. The book thus encompasses clinical renal transplantation, tissue engineering, biomaterial sciences, stem cell biology, and developmental biology, as they are all applied to the kidney. Focuses on the synergy between renal organ transplantation and regenerative medicine, highlighting the advances within transplantation, bioengineering, regeneration, and repair Educates the transplant community on important regenerative medicine research pertinent to kidney transplantation Develops a shared language for clinicians, surgeons, and basic researchers to reach across the fields of transplantation and regenerative medicine, and facilitate more productive investigation and research Catalogs the technologies being developed and methods being implemented to bioengineer or regenerate kidneys to restore function
