Itga11 knockdown decreased fusion index. Fusion index of MSC cultures seeded at 5×103 cells/cm2 on Matrigel®. Cultures were compared every 24 h after myogenic differentiation induction by serum starvation. Cultures were untreated (black), treated with plasmid containing negative control shRNA (dark grey), treated with plasmid containing shRNA for Itga4 (light grey) or for Itga11 (white), see Methods. Standard errors were calculated using triplicate and the Student t-test determined significant differences between control and treated cultures. ***p < 0.1%.
