Show more This thesis describes to which extent the skin reflects the aging process, with a specific focus on cellular senescence. Since the first descriptions of the growth arrested state of fibroblasts upon multiple replication rounds, cellular senescence has now emerged as a promising target to regulate the aging process in vivo as well. Here, we study whether fibroblast senescence in vitro is associated with in vivo donor characteristics such as chronological age and prevalence of disease. We further describe in this thesis whether senescence in skin tissue (in situ) is associated with other histological skin characteristics and with in vivo donor characteristics. Show less
