Figure Legend Snippet: VEGF induces angiogenesis and high integrin expression in differentiated MSCs. (a) DiI-Ac-LDL uptake assay in differentiated MSCs. Parallel experiments in HUVECs served as a positive control. (b) Percentages of MSCs that incorporated DiI-Ac-LDL were calculated, and the data were expressed as percentages compared with the overall cell count. ∗∗ P < 0.01, n = 3. (c) MSCs seeded onto a basement membrane-like gel were treated with VEGF for 4, 7, and 14 days. VEGF-free MSCs were seeded onto a basement membrane-like gel for 7 days (Control group). (d) Capillary-like structures were quantified by measuring the polygonal network. (e) After MSCs were cultured in EC differentiation medium for 7 d, integrins α 1, α 5, and β 1 were examined by qPCR. ∗ P < 0.05; ∗∗ P < 0.01, n = 3. (f) Western blotting assay for integrins α 1, α 5, and β 1. (g) The relative quantification of the protein expression was statistically analyzed using Image J software. ∗ P < 0.05; ∗∗ P < 0.01, n = 3.

Figure Legend Snippet: MRTF-A is essential for the VEGF-induced angiogenesis of differentiated MSCs and integrin α 1, α 5, and β 1 expression. (a) After transfection with sh-MRTF-A or pSUPER (control), MSCs were cultured with EC differentiation medium for 3 d. MTT assay was performed to test the viability of MSCs. (b and c) MSCs were differentiated into ECs by treatment with VEGF for 7 d and siRNA-mediated knockdown experiments were then performed in the MSCs-derived ECs. The migratory ability of MSC-derived ECs transfected with si-MRTF-A or control siRNA was determined via wound healing (b) and transwell chamber assays (c). (d) Cell migration was quantified by calculating relative cell numbers. ∗∗ P < 0.01, n = 3. (e) After differentiation and siRNA or shRNA-mediated knockdown, the cells were cultured in matrigel for 7 d. Morphological changes in differentiated cells transfected with siMRTF-A or sh-MRTF-A were observed. (f) Capillary-like structures were quantified by measuring the polygonal network. ∗∗ P < 0.01, n = 3. (g) The expression of integrins α 1, α 5, and β 1 was estimated by qPCR. ∗ P < 0.05; ∗∗ P < 0.01, n = 3. (h) The expression of integrins α 1, α 5 and β 1 was estimated by western blot. (i) The relative quantification of the protein expression. ∗ P < 0.05; ∗∗ P < 0.01, n = 3.

Figure Legend Snippet: MRTF-A activates the transcription of integrins α 1 and α 5 by binding to the CArG box with their promoters. (a and b) Luciferase assays were performed 24 h after transfection of MRTF-A and integrin α 1/integrin α 5 promoter-luc plasmids into MSCs, COS-7 cells and HUVECs. ∗ P < 0.05; ∗∗ P < 0.01, n = 3. (c and d) ChIP assays were performed in MSCs treated with VEGF at d2, d4, and d7. Cross-linked chromatin was immunoprecipitated with specific anti-MRTF-A antibody. The precipitated chromatin DNA was then purified and amplified by reverse transcription PCR (c) and real time PCR (d) with specific primers that spanned CArG boxes in integrin promoters. The negative control in the immune-precipitation was performed with IgG antibody.

Figure Legend Snippet: VEGF induces angiogenesis and high integrin expression in differentiated MSCs via the Rho signaling pathway. (a) MSCs were cultured with EC differentiation medium in the presence or absence of the Rho inhibitor C3 transferase or the Rho-associated protein kinase (ROCK) inhibitor Y27632 for 4 d and then MTT assay was performed to test cellular viability. (b) MSCs were pretreated with either the C3 or Y27632 in the present of VEGF for 4 d and then continuously cultured in EC differentiated medium for 3 d. Matrigel angiogenesis assays were then performed. (c) Capillary-like structures were quantified by measuring the polygonal network. (d) The expression of integrins α 1, α 5 and β 1 during endothelial differentiation of MSCs was estimated by real-time PCR. ∗∗ P < 0.01, n = 3.
