Effects of Camphorquinone on Cytotoxicity, Cell Cycle Regulation and Prostaglandin E2 Production of Dental Pulp Cells: Role of ROS, ATM/Chk2, MEK/ERK and Hemeoxygenase-1
Fig 1
Morphology of human dental pulp cells after exposure to CQ for 24 hours.
(A) Control (solvent), (B) 1 mM CQ, (C) 2 mM CQ, (100x, original magnification), (D) Quantitative cytotoxicity of CQ on dental pulp cells as analyzed by MTT assay. Results were expressed as % of control (as 100%). *denotes statistically significant difference (p<0.05) when compared with solvent control group.
