L-theanine treatment increased the ADSC proliferation and protein secretion, and decreased the death rate of ADSCs. A Cell proliferation of ADSC with (black bar) or without (white bar) L-theanine treatment were examined by CCK8 proliferation kit at 0 h and 48 h post cell seeding. B The percentage of dead ADSC cells after 48 h-culture were detected by trypan blue staining. The data showed the dead cell percentage of ADSC with L-theanine treatment compared to ADSC without treatment. C The total protein amounts of cultural media were determined by BCA protein assay
