Fig. 5From: Evaluating the oxysterol combination of 22(S)-hydroxycholesterol and 20(S)-hydroxycholesterol in periodontal regeneration using periodontal ligament stem cells and alveolar bone healing modelsEffect of oxysterols on LXR and Hh signaling. Cells incubated with SS at different concentrations (0.5, 1, and 5 μM). a Protein levels of LXRα (50 kDa) and LXRβ (56 kDa). b mRNA expression of LXRα, LXRβ, and ABCA1. c Protein levels of Smo (85 kDa) and Gli1 (118 kDa). Values reported as means ± SD of four independent experiments. *P < 0.05 vs control value.
