Book Description
"Aging is accompanied by cellular, extracellular and systemic changes that impair tissue function. Stromal alterations, such as degeneration of the extracellular matrix, are thought to contribute to organ deterioration in the elderly, yet little is known whether this is caused by changes in fibroblasts, the main cellular component of stroma. Using population- and single-cell whole transcriptomics, as well as long-term lineage tracing, we studied if and how murine dermal fibroblasts are altered during physiological aging. Old dermal fibroblasts not only reduce the expression of genes involved in the formation of the extracellular matrix but, intriguingly, also gain adipogenic traits. Many of these age-related alterations are influenced by systemic changes in metabolism: long-term caloric restriction prevents them in old fibroblasts in a reversible manner, whereas a high-fat diet potentiates them in young fibroblasts. Single-cell RNA sequencing detects two fibroblast subtypes in adult dermis: one characterized by expression of collagens, and the other characterized by expression of genes involved in processes of oxidation-reduction and immune regulation. We show that the identity of these two populations becomes blurred with age, and that gene expression of old fibroblasts is noisy. Our results therefore highlight that identity-noise and the acquisition of adipogenic traits are mechanisms that accompany fibroblast aging, which is sensitive to changes in systemic metabolism." -- TDX.

Book Description
This new volume in the Subcellular Biochemistry series will focus on the biochemistry and cellular biology of aging processes in human cells. The chapters will be written by experts in their respective fields and will focus on a number of the current key areas of research in subcellular aging research. Main topics for discussion are mitochondrial aging, protein homeostasis and aging and the genetic processes that are involved in aging. There will also be chapters that are dedicated to the study of the roles of a variety of vitamins and minerals on aging and a number of other external factors (microbiological, ROS, inflammation, nutrition). This book will provide the reader with a state of the art overview of the subcellular aging field. This book will be published in cooperation with a second volume that will discuss the translation of the cell biology of aging to a more clinical setting and it is hoped that the combination of these two volumes will bring a deeper understanding of the links between the cell and the body during aging.

Book Description
Dermal fibroblasts are the most numerous cells within the dermal layer of skin. The main function of fibroblasts is to preserve the structural integrity of skin through constantly secreting extracellular matrix. Various factors diversely affect the secretion activities of fibroblasts and may lead to varying disease processes (eg: solar damage and wrinkles). This book gathers important cutting-edge research in the field of fibroblasts covering characterisation of fibroblasts and their roles in multiple disease processes such as hypertrophic scarring, ageing/photoaging, diabetic wound healing, cancer, and pachydermoperiostosis. In addition, the chapters also deal with the stem cell-like properties of fibroblasts, which sheds new light on the commonly used definition of fibroblasts and provides novel insights into many past studies performed with fibroblast preparations, since the reported effects might be greatly attributable to stem cell content within these fibroblasts. Additionally, this book features an introduction of the reprogramming of dermal fibroblasts into patient-specific induced pluripotent stem cells (iPSCs) that can be converted into varying terminally differentiated cells. Application of iPSCs is a rapidly developing research field because reprogrammed iPSCs from dermal fibroblasts provides a great tool for studying molecular mechanisms of disease, development, and tissue regeneration. This book is certain to have broad appeal and should provide a useful resource for researchers, students, teachers, and physicians interested in the field.

Book Description
Our skin changes as we age. It becomes thinner and loses fat, making it less plump and smooth. Clinically, aged skin is characterized by wrinkles, sagging, age spots and dryness. Emphasizing laboratory and clinical research, this book comprehensively describes the molecular mechanisms of human skin-aging and age-related skin diseases. This includes

Book Description
This volume provides protocols describing the isolation and culture of diverse cell types stemming from the skin and the use of these cells and cell constructs for wound healing, bioengineering applications, and translational medicine purposes. The book is divided into three sections describing the isolation and culture of diverse skin cells, managing these cells within co-culture systems and skin models, as well as using these skin models in a test setting. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Skin Tissue Engineering: Methods and Protocols serves as a vital aid to basic and clinical researchers such as biologists, physicians, and biomedical engineers working with and being interested in basic science, and clinically and laboratory-applicable translational regenerative medicine.
