DL data from hDPSCs in response to PBM according to pulse frequency. The measured DL in the period between 1 s and 6 s after PBM was plotted with theoretical fittings. DL was measured when hDPSCs were in PBS with no treatment (A), with pre-treatment in rotenone (B), with pre-treatment in AMA (C), and with pre-treatment in NAC (D).
