After publication of the original article  the authors found the following errors had occurred:
The imaging photo was incorrectly selected for Fig. 4. The original article contains imaging relating to another series. An updated version of Fig. 4 is included with this Correction.
In the original Fig. 5b figure legend, reference is made to an HE stain, however this has been made incorrectly. All references to an HE stain should therefore be omitted. The entirety of Figure legend 5b is included below, with the amendments made to the first sentence (which is included in bold for reference):
Figure legend 5b:
Microscopic examination of HLF (left; ×100 magnification) and HMV-I tumors (right; ×200 magnification) that displayed suppressed tumor growth. HLF tumors treated with 520d/atelocollagen exhibited GFP-expressing muscle tissues, including undifferentiated tumor cells unaccompanied by necrosis. HMV-I tumors treated with 520d/atelocollagen showed undifferentiated neoplastic cells. This finding is not inconsistent, as malignant melanomas are observed to be accompanied by extensive necrosis, as shown around A.
A corrected version of Fig. 5 is included with this Correction.
