Background: Beta-galactosidase is the most widely used biomarker for highlighting the processes of cellular aging, including neurodegeneration. On this basis, we decided to test in vitro whether a set of rescuing/reparative events previously observed by us in subjects treated with radioelectric asymmetric conveyor (REAC) technology may also involve antagonism of a marker of aging-related degenerative processes, as assessed by a reduction in beta-galactosidase at the cellular level.
Methods: Human adipose-derived stem cells were cultured at different passages, ranging from 5 to 20, with or without REAC exposure for 12 hours. The cells were then processed for biochemical beta-galactosidase staining and morphological microscopy analysis.
Results: We observed a significant reduction in expression of senescence associated-beta-galactosidase, and a persistence of fibroblast-like morphology typical of human adipose-derived stem cells, even at late passages.
Conclusion: Our results indicate the ability of REAC technology to counteract in vitro senescence of human adipose-derived stem cells, and prompt the hypothesis that such technology may be exploited to antagonize in vivo senescence of tissue-resident or transplanted stem cells playing an important role in clinical treatment of age-related processes.
