YAP and TAZ modulate actin polymerization and stress fiber formation. (A) F-actin, visualized with Alexa Fluor 488 phalloidin. (B) Fluorescent intensity line profiles of phalloidin, three cells per condition. (C) F- and G-actin visualized by Alexa Fluor 488 and 594 phalloidin and DNase I, respectively. (D) F- and G-actin intensity (P > 0.11) and F-/G-actin ratio per cell, normalized to siControl; n = 60 cells; P < 0.005; ANOVA with Tukey’s post hoc test. (E) WT or YAP/TAZ conditional knockout (cKO) BMSCs 14 d after osteoinduction actin visualized with Alexa Fluor 488 phalloidin. (F) Actin fluorescent intensity; line scans are the average of three cells per condition, distance normalized to the largest cell in the set. (G) Line profile fluorescence. n = 39–60 cells; P < 0.0001; two-tailed unpaired Student’s t test. n.s., not significant. Repeated significance indicator letters (e.g., a–a) signify P > 0.05, while groups with distinct indicators (a vs. b; *) signify P < 0.05.
