Fig. 5From: Thymoquinone loading into hydroxyapatite/alginate scaffolds accelerated the osteogenic differentiation of the mesenchymal stem cellsThe release of TQ from the scaffolds slowly continued into the environment up to 48Â h. Calibration curve for standard TQ (A), HPLC peak for a representative standard TQ (B), a representative sample in 60Â s (C), and 24Â h (D).
