Concerns were raised by a third party regarding overlapping image panels within the Supporting Information of the article (Figure S1, Supporting Information ii-Kidney and iv-Lung panels). The authors acknowledged the image compilation error and were able to provide the underlying original raw data. To ensure further accuracy and transparency, the authors returned to the original tissue paraffin blocks and performed new tissue processing. The original and new analyses consistently demonstrated no evidence of toxicity across all experimental groups. Therefore, the corresponding experimental results and the overall conclusions of the paper remain unaffected, and the authors apologize for this error.

The corrected Figure S1 (Supporting Information) is below, and the Supporting information has been updated accordingly:
