Actin assembly in Leigh syndrome fibroblasts. (A) Micrographs of actin staining (TRITC-phalloidin, green) around mitochondria (Tom20, red) for control and Leigh syndrome fibroblasts. Scale bars are 10 µm (full cell) and 5 µm (inset). (B) Table giving P values for comparisons of graph in Fig. 4 I using unpaired Student’s t test. Ctrl #1–2 were combined for analysis. Number of experiments and sample sizes are provided in Table S1.
