In the version of this Article originally published, in Fig. 4f, the asterisk was missing; in Fig. 6a–c, the labels ‘Wnt/β-catenin signalling’, ‘Wnt/Ca+ pathway’ and ‘ERK’ and their associated lines/arrows were missing; and in Fig. 6d and in the sentence beginning “In MSCs that were...”, ‘myosin’ and ‘nanostimulated’, respectively, were spelt incorrectly. These errors have now been corrected in all versions of the Article.
