Fig. 8From: The preconditioning of lithium promotes mesenchymal stem cell-based therapy for the degenerated intervertebral disc via upregulating cellular ROSPrevention of ROS generation attenuated the effects of LiCl preconditioning to ADSC. a Relative cell number of ADSC microsphere. b The ECM content of ADSC microspheres determined using Alcian Blue staining, scale bar = 50 μm. c The immunofluorescent staining of aggrecan in ADSC microspheres, scale bar = 50 μm. d Quantitative analyses of aggrecan content. e, f ERK1/2 and pERK1/2 expression of preconditioned ADSC with or without APO treatment. g, h the mRNA expression of MMP13 and ADAMTS5 of preconditioned ADSC with or without APO treatment. Error bars depict Mean ± SD. (***P < 0.001, **P < 0.01, *P < 0.05)Back to article page
