Figure Lengend Snippet: Immunohistochemical Staining Results Immunohistochemical staining and analysis of osteogenic-related proteins and signaling pathway markers in distraction areas at consolidation weeks 2, 4 and 6. Staining for Runx2, Osterix (Osx), osteopontin (OPN), osteocalcin (OCN), phosphorylated PKA (p-PKA), and phosphorylated CREB (p-CREB) across different treatment groups. Quantitative analysis shows positive staining area percentage (n = 3). Scale bar: 200 μm.
Article Snippet: Membranes were blocked with TBST buffer containing 5 % skimmed milk at room temperature for 1–2 h. Subsequently, PVDF membranes were incubated overnight at 4 °C with specific primary antibodies including PKA antibody (Affinity, AF7746), phosphorylated PKA antibody (Affinity, AF7246), CREB antibody (Affinity, AF6188), phosphorylated CREB antibody (Affinity, AF3189), OPN antibody (Affinity, AF0227), OCN antibody (Affinity, DF12303) (Affinity Biosciences, USA); Runx2 antibody (Abcam, ab236639), Osx antibody (Abcam, ab209484), CyclinD1 antibody (Abcam, ab134175), GAPDH antibody (Abcam, ab181602) (Abcam, UK).
