Fig. 5From: Triptolide mitigates the inhibition of osteogenesis induced by TNF-α in human periodontal ligament stem cells via the p-IκBα/NF-κB signaling pathway: an in-vitro studyTriptolide reduces the level of inflammatory factors induced by TNF-α in hPDLSCs. (A) Relative IL-6 mRNA expression in hPDLSCs after osteogenic induction for 7 days under control, TNF-α, TNF-α (20ng/ml) and triptolide (10− 11M) treatment. (B) Relative expression of IL-8 mRNA in hPDLSCsBack to article page
