Human oral epithelial cells and fibroblasts

Human oral epithelial cells and fibroblasts are the primary cellular components of the oral mucosa, which serves as the protective lining of the oral cavity (StatPearls: NBK544286). Oral epithelial cells, mainly keratinocytes, form a stratified squamous barrier that protects underlying tissues from mechanical trauma, chemical irritation, and microbial invasion (PubMed: 25653551). Fibroblasts reside in the underlying connective tissue, known as the lamina propria, where they synthesize extracellular matrix components like collagen and play a vital role in tissue repair and wound healing (PubMed: 21859044). These cells are central to the pathogenesis of various conditions, including periodontitis, oral lichen planus, and oral squamous cell carcinoma (PubMed: 30631112, PubMed: 28605913). However, they represent a tissue environment or cell population rather than a single druggable molecular target such as a receptor or enzyme. Therapeutic strategies typically focus on modulating specific signaling pathways or molecular targets expressed by these cells, such as growth factor receptors or inflammatory cytokines, rather than targeting the cells themselves as a whole. Consequently, while biologically significant, this entry is classified as a non-molecular target in a pharmacological context.
