[Buccal epithelium as an object for testing of biological age and the speed of aging]
Abstract:
Testing of biological age and the speed of aging is one of the main goal of gerontology and predictive medicine. This review summarizes the ability of using buccal epithelium as target of non-invasive investigation of aging diagnostics. Buccal epithelium used for thelomere test and morphological characteristics of its nucleus demonstrate the speed of aging. The electrophysiological investigation of buccal cells nucleus are the markers of biological age of a human. In future it can be possible to use buccal epithelium for immunogistochemical investigation with goal to diagnose cellular senescence.
