Acid bone lysate (ABL) decreases osteogenic and adipogenic differentiation. Exposure of osteogenic calvaria cells and adipogenic 3T3-L1 cells to ABL caused a considerable decrease of the marker genes alkaline phosphatase (ALP) and osteocalcin (OC) (a), as well as PPARγ and C/EBP (b), respectively. Chondrogenic ATDC5 cells showed a moderate increase of SOX9 and COL10 (c). Histochemical staining of alkaline phosphatase activity confirmed the findings from gene expression in osteogenic calvaria cells (d). N = 3–5. Data represent the mean ± SD.
