The effect of aging in primary human dermal fibroblasts.

ABSTRACT: Skin aging is a complex process, and alterations in human skin due to aging have distinct characteristic as compared to other organs. The aging of dermal cells and the biological mechanisms involved in this process are key areas to understand skin aging. A large number of biological mechanisms, such as decreasing of protein synthesis of extracellular matrix or increasing of degradation, are known to be altered through skin aging. However, environmental influence can accelerate this characteristic phenotype. In this study, we analyzed primary human dermal fibroblasts in three different in-vitro aging models-UVB irradiation and accelerated proliferation of human dermal fibroblasts from young donors as well as from elderly donors-for the gene expression of COL1A1, COL1A2, COL3A1, COL4A1, COL7
