Fascial spaces of the head and neck Fascial spaces of the head and neck Fascial spaces (also termed fascial tissue spaces or tissue spaces) are potential spaces that exist between the fasciae and underlying organs and other tissues. In health, these spaces do not exist; they are only created by pathology, e.g. the spread of pus or cellulitis in an infection. The fascial spaces can also be opened during the dissection of a cadaver. The fascial spaces are different from the fasciae themselves, which are bands of connective tissue that surround structures, e.g. muscles. The opening of fascial spaces may be facilitated by pathogenic bacterial release of
National Institute of Arthritis and Musculoskeletal and Skin Diseases regulate differentiation and regeneration of skeletal muscle. The ultimate goal of these studies is to provide a practical conceptual PDCTC framework. Laboratory of Oral Connective Tissue Biology—studies the molecular biology of dental-oral-craniofacial development, with a focus on teeth, gums and jaws. The aim of these studies is to understand cells and signals influencing tooth, bone, and periodontal ligament development. Laboratory of Skin Biology—studies the regulation of epidermal differentiation, skin barrier formation, and inflammatory responses associated with barrier dysfunction. A major focus is basic investigation of ectodermal appendage development and the study of human ectodermal dysplasias. Laboratory of Stem Cell Biology—studies
