Figure Lengend Snippet: Effects of GABA on the proliferative activity and molecular markers in BSCs. (A) Immunofluorescence staining for BSCs identification (Desmin, Pax7, and MyoG (green) and nuclei (DAPI, blue) (10×; scale bar = 200 μm). (B–E) CCK-8 analysis of viability after 24, 48, 72, and 96 h treatment with 0.1, 0.5, 1, 2, 5, and 10 mM GABA and CON = 0 mM. (F,G) EdU assay. Hoechst (nuclei, blue) and EdU-positive cells (red) scale bar = 200 μm. (H–M) RT-qPCR. mRNA expression of proliferation-related genes ( CDK2 , PCNA , Ki-67 , Pax7 , Pax3 , CCND1 ) after 48 h treatment with 0.5 and 1 mM GABA. (N,O) Western blotting of PAX7, CDK1, CDK2, and P21 proteins (β-actin loading control). (Mean ± SD; n = 3; groups with different letters a–e differs at p < 0.05).
Article Snippet: Polyclonal antibodies against myogenin (MYOG; BS-3550R, Bioss, Beijing, China), paired box protein 7 (Pax7; AB-528428, Abcam, United Kingdom) and desmin (BS-20702R, Bioss, Beijing, China) were each diluted 1:100 in PBS containing 5% bovine serum albumin (BSA) and incubated overnight at room temperature.
