[Corrigendum] Exosomes derived from Piwil2‑induced cancer stem cells transform fibroblasts into cancer‑associated fibroblasts.

Following the publication of the above paper, the authors have realized that they made an error during the assembly of the western blotting data in Fig. 4; essentially, the western blotting data shown for the FAP experiment in Fig. 5 were mistakenly inserted into Fig. 4 to show the metalloproteinase‑9 (MMP‑9) data. The authors re‑examined their original data, and discovered how the error in the compilation of Fig. 4 arose. The corrected version of Fig. 4, incorporating the correct data for the MMP‑9 experiment, is shown below. Note that this error did not affect the overall conclusions reported in the study. The authors are grateful to the Editor of for allowing them the opportunity to publish this Corrigendum; furthermore, they apologize for any inconvenience caused to the readership of the Journal.
