L-quebrachitol is a natural product.L-quebrachitol may promote osteoblastogenesis by triggering the BMP-2-response as well as the Runx2, MAPK, and Wnt/β-catenin signaling pathway.

The total RNA from cells treated with l-quebrachitol was extracted using the TriPure Isolation Reagent .RNA (1 μg) was reverse transcribed using the Transcriptor First Strand cDNA Synthesis Kit to cDNA.The qRT-PCR analysis was performed using the EvaGreen HRM Mix .GAPDH was used as an internal control.The relative expression ratio was calculated using the 2^?△△Ct method.
