Corrigendum to “Hyaluronic acid-functionalized poly-lactic acid (PLA) microfibers regulate vascular endothelial cell proliferation and phenotypic shape expression” Colloids Surf. B: Biointerfaces 206 (2021) 111970 (Colloids and Surfaces B: Biointerfaces (2021) 206, (S0927776521004148), (10.1016/j.colsurfb.2021.111970))

The authors regret that the white dotted line box in the SEM image of the upper panel of Fig. 1b is missing, and the SEM images of the PLA sample on the right panel in Fig. 1b are incorrectly placed. Fig. 1b and the corresponding data for PLA sample in 1c are now displayed as below. These corrections do not affect any findings and conclusions reported in this article before. And no additional text corrections are made in the article. The authors would like to apologize for any inconvenience caused.
