This book elucidates the genetic, biological, morphological and functional aspects of telocytes. Telocytes are a recently defined type of interstitial (stromal) cells, with very long (tens to hundreds of micrometres) and very thin prolongations (mostly below the resolving power of light microscopy). The book describes the presence of telocytes in various organs and tissues, details their morphological characteristics, explores their genomic and proteomic profiles, puts forward preclinical evidence of their application, and discusses their potential in the context of clinical therapeutics. As such, it offers a valuable guide for biologists and clinicians alike. Dr. Xiangdong Wang is a distinguished Professor of Medicine. He is Director of the Shanghai Institute of Clinical Bioinformatics, Executive Director of the Clinical Science Institute at Fudan University Zhongshan Hospital, Shanghai, China; Dr. Dragos Cretoiu is an Associate Professor of Pathology at the Department of Cellular and Molecular Medicine, Carol Davila University of Medicine and Pharmacy, Bucharest.
