Figure Lengend Snippet: Mesenchymal cells modulate the effect of Hedgehog (Hh) signaling. ( A , B ) Proliferation analysis of 5-ethynyl-2’-deoxyuridine (EdU)+ MDA-MB-468 and 184B5 cells co-cultured with adipose mesenchymal stem cells (ADMSC) treated with Sonic hedgehog (SHH)-ligand and Hh inhibitors for 96 h. Significance was determined via Student’s t -test, * p < 0.05. ( C ) Expression levels of glioma associated oncogene family zinc finger 1 ( GLI1 ), patched1 ( PTCH1 ) and Smoothened ( SMO ) genes relative to GAPDH at 24 h post-treatment. ( D , E ) Tumor growth curves in xenografted tumors composed by MDA-MB-468 + ADMSC +/− SHH-ligand. Daily dosage with NVP or Vehicle during the last four weeks. Data show the average mean +/− SEM of nine mice per treatment. Significance was determined via ANOVA analysis comparing Vehicle (D) or SHH (E) with NVP, * p < 0.05, ** p < 0.01, **** p < 0.0001. F ) Expression levels of GLI1 , PTCH1 , and SMO relative to GAPDH in xenografted tumors using human and mouse-specific primers. Data represent mean +/− SEM of six mice per condition. No significant differences were observed by Student’s t -test. ( G , H ) Percentage of mice with visible metastases. Significance was determined by Fisher’s exact test, * p < 0.05.
