Fig 1: The graph illustrates the changes in mean BMP-2 expression, measured by absorbance according to ELISA assay guidelines (Abcam, ab277085), throughout the experiment at different time points (0, 14 and 21 days), depending on the applied cell culture conditions and rosavin supplementation. The groups are color-coded as follows: (●) gray represents DMEM g, (●) orange represents DMEM m, (●) yellow represents R50, and (●) red represents R100. Data are presented as mean ± standard deviation (SD). Asterisks (*) indicate statistical significance at p < 0.05.
