Figure Lengend Snippet: Endoglin silencing affects vessel sprout diameter and permeability. ( a ) Three-dimensional (3D) reconstruction of ECFC ctr-siRNA and ECFC Eng-siRNA to evaluate sprout diameter. In green, Actin F (Alexa 488), and in red, nuclei (TOPRO-3) are stained (scale bar, 150 µm). ( b ) When Eng is suppressed, sprouts are wider than in controls (*** p < 0.001). ( c ) Using a real-time impedance-based cell analyzer (iCELLigence system, ACEA Biosciences, San Diego, USA), ECFC ctr-siRNA and ECFC Eng-siRNA are analyzed in basal condition and under 20 ng/mL TNFα stimulation (gray and black lines, respectively). As shown by the quantification in ( d ), a significant difference between ECFC ctr-siRNA (white column) and ECFC Eng-siRNA (black column) is found 12 h after TNFα stimulation (* p < 0.05). ( e ) Immunofluorescence staining for VE-CAD in ECFC-ctr and ECFC Eng-siRNA with the absence of or in the presence of 20 ng/mL TNFα for 1 h (scale bar, 22 µm). ( f ) Quantification of the pictures in ( c ) does not show differences between control and Eng-siRNA in terms of VE-CAD membrane staining nor of fluorescence intensity in the presence of TNFα (* p < 0.05).

Figure Lengend Snippet: Endoglin silencing affects cofilin dynamics. ( a , b ) Western blot performed on n = 5 different clones of ECFC at passage 3–4, <30 days. A representative experiment is shown. Eng silencing in ECFC reduces P-Cofilin, suggesting an increased activity of cofilin when Eng is downregulated. Actin and tubulin were used as loading controls. The last row displays the reduced expression of Eng after siRNA silencing. ( b ) Quantification of five different ECFC clones shows a significant difference (*** p < 0.001) between ctr-siRNA and Eng-siRNA in the P-Cofilin/Total-Cofilin ratio. ( c ). Using a real-time impedance-based cell analyzer (iCELLigence system, ACEA Biosciences), ECFC controls (DMSO) and ECFC treated by LIMKi were analyzed in basal condition and under 20 ng/mL TNFα stimulation (gray and black lines, respectively). As shown by the quantification in ( d ), a significant difference between control ECFC (gray bar) and ECFC treated with LIMKi (black bar) 12 h after TNFα stimulation (** p < 0.01). ( e , f ) Immunofluorescence for F-actin in ECFC controls vs. ECFC Eng-siRNA +/−TNFα ( e ) and ECFC controls vs. ECFC LIMKi +/−TNFα ( f ). (scale bar, 22 µm). ( g ) The quantification of ( e ) and ( f ) confirms that ECFC Eng-siRNA and ECFC LIMKi display the same modifications in terms of F-actin (* p < 0.05).
