“…Fibroblasts play important roles in maintaining cell morphological and physiological characteristics, as well as in regulating the physiological function of skin. Research has shown that fibroblasts in derma can secrete various cytokines and extracellular matrix components, which function in regulating cell growth, proliferation, differentiation, and migration [8][9]. Additionally, fibroblasts can secrete inflammatory factors that influence skin irritation, allowing fibroblasts to be utilized in a highly sensitive assay to predict the potential for human skin irritation [10].…”
