Stem Cells and Signaling Pathways provides mechanistic insights into the role of stem cells to combat the COVID-19 outbreak and other pathologies where a cytokine storm is the cause of concern for e.g., radiation exposure, multiple organ failure and sepsis. The advent of SARS-CoV-2 resulted in a global pandemic, putting individuals with other comorbidities at a higher risk of infection. The whole world witnessed a massive shortage of medical and other essential supplies needed to combat the virus. That said, stem cell therapy has emerged as a potential treatment for viral diseases, including but not limited to COVID-19. Interestingly, the clinical trials in the patients having COVID-19 complications depicted faster recovery in patients post mesenchymal stem cells therapy owing to the decreased cytokines levels, anti-viral effects and regeneration of the infected tissue. • Provides a compilation of chapters dedicated to the study of the field with respect to properties of stem cells and their signaling pathways. It also provides detailed information on signaling pathways associated with stem cells.• Provides a detailed and updated view of stem cell biology.• Covers a wide range of areas within basic and translational research appropriate for scientistsand clinicians engaged in studying the treatments for diseases from interdisciplinary perspectives.• Highlights the use of different models for stem cell research, significance of stem cell signaling in drug discovery.

Cancer Stem Cells and Signaling Pathways explores the mechanism of cancer stem cell signaling pathways in cancer advancement, serving as an ideal reference guide for investigators with valuable answers to problems associated with anti-cancer treatments and an understanding of the crosstalk among the signaling pathways in CSC regulation. Despite recent advances in tumor therapy and a greater understanding of their biology, tumors continue to be a prevalent and fatal worldwide. According to a novel paradigm in tumor biology, a small percentage of the cells within a tumor known as cancer stem cells (CSCs) are predicted as a crucial population for tumor progression. - Presents cancer stem characteristics and their signaling pathways - Highlights the use of animal models for cancer research, the use of genetically modified stem cells to deliver antitumor agents, and the significance of stem cell signaling in drug discovery - Covers basic and translational research appropriate for scientists and clinicians exploring alternative treatments for various cancers

Stem Cells and Aging covers what is known about the effect of time and age on the basic units of life, which are the corresponding tissue-specific or adult stem cells. Even though the concept of stem cells was introduced nearly a century ago by Alexander Maximow, modern stem-cell research began in 1963 when James Till, Ernest McCullough and Lou Siminovitch established assays to detect hematopoietic stem cells. In fact, given the importance of the aging-associated diseases, scientists have developed a keen interest in understanding the aging process as they attempt to define the role of dysfunctional stem cells in the aging process. With an aging population worldwide, understanding these age-related stem cell changes at a basic biology level and at the level of their influences for regenerative medicine is of interest and importance. There is increasing evidence that the aging process can have much adverse effects on stem cells. In the modern era, one of the emerging fields in treating human diseases is stem cell research, as stem cells have the remarkable potential to treat a wide range of diseases. Nevertheless, understanding the molecular mechanism involved in aging and deterioration of stem cell function is crucial in developing effective new therapies for aging. - Serves as an ideal reference to guide investigators toward valuable answers to the problems of our aging population - Addresses the effect of time and age on human stem cells - Includes chapters from contributors exploring the biology of stem cell aging around the globe

The formation of a complex multicellular organism from a single cell is one of the most amazing processes of biology. Embryonic development is characterised by the careful regulation of cellular behaviours such that cells proliferate, migrate, differentiate and form tissues at the correct place and time. These processes are genetically controlled and depend both on the history of cells, their lineage, and on the activities of signalling pathways, which coordinate the cell interactions leading to organogenesis. The aim of the Frontiers research topic “Signalling pathways in embryonic development” has been to provide a forum for experts in cell and developmental biology to share recent advances in the field of signalling during embryonic development. Sixteen articles in a variety of formats are united in this Topic, offering a valuable collection for researchers looking for an update in the knowledge of signalling pathways operating during embryogenesis. The works, focused mainly on vertebrates, explore different aspects of this theme from cell communication to organ formation and have implications for areas as distant as evolution or pathology. Understanding developmental signalling pathways is important for several reasons. It gives us information about basic mechanisms of cell function and interactions needed for morphogenesis and organogenesis. It uncovers the basis of congenital malformations, since errors at any step of cell signalling during development are a major cause of defects. This fundamental insight gives us clues to understand the mechanisms operating in evolution that explain diversity in form and function. And finally, it allows the identification of possible causes of disease in the adult organism (such as cancer or degenerative diseases) pinpointing possible targets for therapeutic approaches.

The main objective of this book is to provide a comprehensive review on stem cells and their role in tissue regeneration, homeostasis and therapy. In addition, the role of cancer stem cells in cancer initiation, progression and drug resistance are discussed. The cell signaling pathways and microRNA regulating stem cell self-renewal, tissue homeostasis and drug resistance are also mentioned. Overall, these reviews will provide a new understanding of the influence of stem cells in tissue regeneration, disease regulation, therapy and drug resistance in several human diseases.

This book entitled “Cancer Stem Cell Markers and Related Network Path-ways” is about cancer stem cell (CSC) markers and the molecular network pathways. CSCs play an important role in the cancer drug resistance, metastasis and recurrence. Epithelial-mesenchymal transition (EMT) is closely related to CSC phenotype. This book covers various aspects of the molecular networks related to CSCs including the important phenotypic change such as EMT. Readers will discover the importance of the identification of CSC markers and EMT-related molecules in CSC network pathways. The CSC signaling pathways and EMT molecular network pathways attract researchers in the field to define the cancer therapeutic targets. Cancer environment is important in the acquisition of CSC phenotype in cells. The revealing of this CSC mystery is across 7 chapters. The topic of this book is particularly relevant to research in the field of cancer and stem cells, as well as the network pathways. We hope that this book helps the readers to be interested in understanding why the CSC concept is important and attractive.
