Cellular aging in Werner's syndrome: a unique phenotype?
Werner's syndrome is commonly regarded as a model for the study of premature aging. There are, however, a variety of clinical and pathologic anatomical features that clearly distinguish it from aging in normal individuals. In this paper we report on in vitro cytogenetic and cell fusion studies that indicate cultured fibroblast-like cells derived from Werner patients differ from cells of normal donors. Despite these discordances with "natural" aging, however, Werner's syndrome, like several other "segmental progeroid syndromes," may prove useful for the investigation of selected aspects of the aging process and of age-related diseases.
