Abstract :

Advancing age is associated with several diseases and disorders due to multiorgan atrophy. The increasing proportion of elderly humans demands the identification of means to counteract aging and age-associated disorders. There is an increased depletion of stem cells in the aged organs, resulting in their inability to repair the damage and hence organ degeneration. Stem cell therapy has been implicated in counteracting aging and shown promise. However, the use of stem cells encounters several side effects and complications such as handling and storage of the cells for transplantation purpose. Stem cells secretome has proven to be of significant importance in a variety of disorders. In this study, we have shown that secretome derived from dental pulp stem cells (DPSCs) can reverse the age-associated degeneration induced by chronic exposure to d-galactose in a rat model. The secretome was able to increase muscle grip strength and animal activity. Secretome also improved the kidney function and hepatic biochemistry similar to healthy controls as evaluated by renal function test and Fourier-transform infrared spectroscopy. We also showed that secretome reduced the levels of monoamine oxidase and acetylcholinesterase in the brain and liver, indicating aging reversal. Finally, proteomic profiling of DPSCs secretome revealed the presence of 13 proteins which have antiaging functions. Thus, our study provides first proof of concept that DPSCs secretome can render protection against d-galactose induced accelerated aging.
