ITGA5 Controls IGF2/IGFBP2 Expression in hMSCs. Adult hMSCs were transduced with shITGA5, shITGB1 or a non relevant shRNA (shNR), total RNA was used for quantitative RT-PCR analysis of IGF2 (A) and IGFBP2 (B). Adult hMSCs were transduced with a lentiviral vector encoding ITGA5, or treated with the agonist peptide CRRETAWAC (100 μg/ml) (CRRETAWAC) or with a non relevant control peptide (GRGESP; 100 μg/ml), or with a conformation-dependent anti-α5 monoclonal antibody (SNAKA51; 10 μg/ml), and IGF2 and IGFBP2 mRNA expression was determined by quantitative RT-PCR analysis (C-D). Results are expressed as mean ± SD of treated over control ratio after normalization to 18 S expression. *: significant difference with untreated cells (P <0.05).
