Correction: MAGIC-factor 1, a partial agonist of MET, induces muscle hypertrophy by protecting myogenic progenitors from apoptosis (PLoS ONE (2008) 3:9 (e3223) 10.1371/journal.pone.0003223)

Abstract

After publication of this article [1], the following concerns were raised about the figures: • Figure 2E follistatin and GAPDH panels contain background irregularities such that lane 1 appears to have a different background to lanes 2-6; • Figure 3B Magic-F1 and HGF panels contain background irregularities such that lanes 1-3 appear to have a different background to lanes 4-6; • Fig 5A WT 3d and WT 7d panels appear similar. Regarding Fig 5A, the authors clarify that the bottom images at 3d and 7d for WT have been erroneously swapped. In the published paper the image below 3d should be below 7d, and vice versa. This is a double IF analysis to test embryonic myosin (red) and laminin (green). Thus all WT upper panels are same images of below using a different light channel. The authors have provided the original images used in Figures 2E and 3B. The original images do not contain background irregularities and the source of the image artifact is unclear. With this correction, the authors provide an updated Fig 5, along with the original images underlying Figs 5A, 2E, and 3B (in Supporting Information S1 File) [figure presented].
