In the version of this article initially published, values for 12-week Iba-1 (blue curve in column 3, row 3: Fig. 2f) and 1-year GFAP (blue curve in column 4, row 2: Fig. 2f) of the control samples (thin film) were inadvertently mixed up, resulting in incorrect data shown in Figure 2h,i; Figure 2 source data; and the P values in the corresponding Supplementary Tables. Additionally, in Extended Data Figure 6a, the traces at 11 months were accidentally plotted for all months. The figures, source data and supplementary information have been updated in the HTML and PDF versions of the article. These changes do not affect the results or conclusions of the study.
