Tissue-Specific Matrix Control Of Cell Cohesion And Migration Signaling Complexes, Tristen Tellman
Dissertations & Theses (Open Access)
The extracellular matrix (ECM) is a complex, interconnected network of three major constituents: collagens, glycoproteins, and proteoglycans, along with their enzyme modifiers. Within this network and beyond the structural role, each ECM molecule contributes a context-specific signal that influences cellular fate and behavior. Among these behaviors, cellular migration provides an essential function in developing tissues, wound healing, and cancer cell metastasis. Using two glandular organs, the normal salivary gland and the cancerous prostate, this dissertation describes the tissue-specific composition of two ECM signaling complexes (type I hemidesmosomes and the perlecan-semaphorin 3A-plexin A1-neuropilin-1 (PSPN) complex) and translates this knowledge into viable …
