Abstract (original English)
Current clinical approaches to treat irradiation-induced salivary gland hypofunction are ineffective. We previously reported that adipose-derived stem cell (ADSC)-based therapy ameliorates damaged salivary gland function in mice and that the effects were enhanced when the therapy was co-administrated with platelet-rich fibrin (PRF). We examined the feasibility of ADSC transdifferentiation into salivary gland acinar-like cells (SGALCs) and analyzed the potential of PRF to promote the transdifferentiation process in vitro. Salivary gland cells (SGCs) and ADSCs were indirectly co-cultured using Transwell inserts, and increasing concentrations of PRF-conditioned medium were applied to the co-culture system. The expression of α-amylase and AQP-5 were used to evaluate ADSC transdifferentiation. Notably, on day 7, 14, and 21, expression of both α-amylase and AQP-5 were detected in the co-cultured ADSCs. Additionally, PRF increased α-amylase and AQP-5 levels in ADSCs that were co-cultured for 7 days. These data demonstrate that ADSCs have the potential to transdifferentiate into SGALCs and that PRF can promote the transdifferentiation process. Therefore, these data reveal a possible mechanism to treat irradiation-induced salivary gland hypofunction and have translational medicine implications.
