|sc-12-0871_sm_SupplFigure1.TIF||211K||Supplemental Figure 1. c-Cbl regulates STAT5 ubiquitination in murine MSC. (A) representative Western blot and quantification of multiple blots from separate experiments (B) showing the effects of sh-c-Cbl1 and sh-c-Cbl2 on c-Cbl and Cbl-b protein levels in murine C3H10T1/2 cells compared to empty vector (EV). *P<0.05 vs EV. (C) Cell lysates from C3H10T1/2 cells transduced with sh-c-Cbl1, sh-c-Cbl2 or the empty vector were immunoprecipitated with anti-STAT5 antibody and immuno-precipitates were analysed by immunoblotting (IB) with STAT5 or ubiquitin antibodies (C). Total lysates and IgG immunoprecipitates were used as controls.|
|sc-12-0871_sm_SupplFigure2.TIF||83K||Supplemental Figure 2. c-Cbl silencing does not modulate total STAT3 in human MSC. Representative Western blot (A) and quantification of multiple blots (B) showing that c-Cbl silencing in human F/STRO-1+A cells slightly increased phospho-STAT3 but had no effect on total STAT3 protein levels. *P<0.05 vs sh-Control.|
|sc-12-0871_sm_SupplFigure3.TIF||168K||Supplemental Figure 3. c-Cbl regulates STAT5 activity in human MSC. STAT5 RE-LUC reporter assay in F/STRO-1+A cells (A) showing the effect of c-Cbl silencing on STAT5 transcriptional activity in the presence or absence of the STAT5 inhibitor (75 μM). Cell lysates from F/STRO-1+A cells transduced with sh-c-Cbl RNA or sh-Control and cultured in the presence or absence of the STAT5 inhibitor (75 μM) were immuno-precipitated (IP) with anti-RUNX2 antibody and immuno-precipitates were analysed by immuno-blotting (IB) with STAT5 antibody. Total lysates and IgG immuno-precipitates were used as controls. a: P<0.05 vs the respective sh-Control; b: P<0.05 vs corresponding untreated cells.|

Effect of the STAT5 inhibitor (75 μM) on the expression of late osteoblast marker genes (A), phenotypic chondrocyte genes (B) and adipocyte genes (C) and in c-Cbl silenced human F/STRO+A cells. a: P<0.05 vs sh-Control; b: P<0.05 vs treated sh-Control.|
