A Cell‐Free Silk Fibroin Biomaterial Strategy Promotes In Situ Cartilage Regeneration Via Programmed Releases of Bioactive Molecules

Adv. Healthcare Mater. 2023, 12, 2201588 https://doi.org/10.1002/adhm.202201588 In the published version of this article, the cytoskeleton image in Figure 4A on the far right (SF-TGF-β1, E7) is a duplicate of Figure 7B in an earlier publication from the same authors (Z. N. Mao, X. W. Bi, F. Ye, X. Shu, L. Sun, J. Guan, R. O. Ritchie, S. J. Wu, ACS Biomater. Sci. Eng. 2020, 6(8), 4512–4522. https://doi.org/10.1021/acsbiomaterials.0c00752), due to a mistake by the authors when compiling the images for their figures from the same file which contained all their images of their cytoskeleton/nuclear staining tests. The new Figure 4 to replace is shown below. The authors confirm that this correction does not affect the overall results and conclusions from this work. The authors apologize for any inconvenience caused.
