Osteogenic simulation in treatment groups. (a) ALP staining assay; concentrated growth factor (CGF) and lipopolysaccharide (LPS) 1 µg/ml, separately or alone, induced alkaline phosphatase (ALP) activity in dental pulp stem cells (DPSCs). (b) Sirius Red staining assay showing higher levels of collagen in the LPS 1 µg/ml, CGF, and CGF + LPS 1 µg/ml groups; and ns = nonsignificant.
