Abstract

Photobiomodulation therapy (PBMT) can improve processes relevant to tissue regeneration, such as survival, proliferation, migration, and differentiation of cells, including stem cells. Thus, PBMT could be applied as auxiliary therapy for tissue regeneration. Cell sheets (CSs) induced by vitamin C (VC) can generate large amount of cells, which would also be useful for tissue regeneration. VC and PBMT cause opposite effects on cell metabolism (e.g., VC is antioxidative, and PBMT generates reactive oxygen species); however, hDPSC CSs were formed when VC and PBMT+VC were applied. Thus, this study showed that PBMT does not interfere with the formation of cell sheets induced by VC. Additionally, PBMT improved the functional differentiation of the cells isolated from the CSs. Thus, due to the clinical benefits of PBMT, the association of this therapy with cell sheets seems promising for future applications in tissue regeneration. (AU)
