Cellular And Molecular Mechanisms At The Proliferation Stage In Wound Healing From Scarring To Tissue Regeneration

New updated edition first published with Cambridge University Press. This new edition includes 29 chapters on topics as diverse as pathophysiology of atherosclerosis, vascular haemodynamics, haemostasis, thrombophilia and post-amputation pain syndromes.

This text book is open access under a CC BY 4.0 license. Written by a group of international experts in the field and the result of over ten years of collaboration, it allows students and readers to gain to gain a detailed understanding of scar and wound treatment – a topic still dispersed among various disciplines. The content is divided into three parts for easy reference. The first part focuses on the fundamentals of scar management, including assessment and evaluation procedures, classification, tools for accurate measurement of all scar-related elements (volume density, color, vascularization), descriptions of the different evaluation scales. It also features chapters on the best practices in electronic-file storage for clinical reevaluation and telemedicine procedures for safe remote evaluation. The second section offers a comprehensive review of treatment and evidence-based technologies, presenting a consensus of the various available guidelines (silicone, surgery, chemical injections, mechanical tools for scar stabilization, lasers). The third part evaluates the full range of emerging technologies offered to physicians as alternative or complementary solutions for wound healing (mechanical, chemical, anti-proliferation). Textbook on Scar Management will appeal to trainees, fellows, residents and physicians dealing with scar management in plastic surgery, dermatology, surgery and oncology, as well as to nurses and general practitioners

Despite enormous advances made in the development of external effector prosthetics over the last quarter century, significant questions remain, especially those concerning signal degradation that occurs with chronically implanted neuroelectrodes. Offering contributions from pioneering researchers in neuroprosthetics and tissue repair, Indwel

'Provides comprehensive detail on the various aspects of particular molecules involved in the phases of injury and repair and the cellular movements and processes....This is an excellent reference book for libraries serving biology and health science clientele and for workers in this field of research.' -American Scientist, from a review of the First Edition All chapters of this second edition have been completely revised and expanded-especially the chapters on growth factors and extracellular matrix molecules. New chapters discuss provisional matrix proteins, extracellular matrix receptors, and scarring versus nonscarring wound healing.

Wound healing has three overlapping steps: 1. coagulation and inflammation, 2. the proliferation and formation of new tissue, and 3. tissue remodeling. The initial phase of acute wound healing is the coagulation and the formation of a temporary wound matrix. This phase begins immediately after the injury and is completed within a few hours. Inflammation is crucial to the clean-up-repair process. Early inhibition of inflammation can hinder regeneration processes. Inflammation is associated with the activation of the innate immune system. At the site of inflammation, neutrophils appear first, followed by monocytes, which may differentiate into macrophages. The main function of macrophages and immune cells is to remove cell debris and microorganisms. These cells, in addition to the functions mentioned below, play an essential role in preparing the next phase by coordinating cellular processes. The second phase starts with the division of the cells. This process allows damaged and lost structures to be replaced. Granulation tissue formed by the extracellular matrix (ECM) and new blood vessels generated by angiogenesis fills the lesion. This process usually takes 2-10 days. In the final phase, the blood vessels regress, the inflammation resolves, and the granulation tissue becomes functional tissue. In this phase, the ECM transforms from a temporary ECM to a permanent collagen matrix. This phase starts 2-3 weeks after injury and can last for years if tissue regeneration is inadequate.

What is a wound, how does it heal, and how can we prevent scarring? The concept of wound healing has puzzled humans even before the advent of modern medicine. In recent years, bioengineering has tackled the problems of cancer, tissue engineering and molecular manufacturing. The broad spectrum of technologies developed in these fields could potentially transform the wound care practice. However, entering the world of wound healing research is challenging — a broad spectrum of knowledge is required to understand wounds and improve healing. This book provides an essential introduction of the field of wound healing to bioengineers and scientists outside the field of medicine. Written by leading researchers from various fields, this book is a comprehensive primer that gives readers a holistic understanding of the field of wound biology, diagnostics and treatment technologies.
