Correction: Chen et al. Multifunctional Injectable Hydrogel Loaded with Cerium-Containing Bioactive Glass Nanoparticles for Diabetic Wound Healing. Biomolecules 2021, 11, 702

The authors would like to replace Figure 4A of the following published paper [1]. The new Figure 4A is attached below.

In the original publication [1], there was a mistake in Figure 4A. We inadvertently used the same image for the Ctrl group and the G group.

Figure 4.

Angiogenic activity evaluation of hydrogels. (A) Representative images of HUVECs transwell migration. (B) The photographical images of HUVECs tube formation by Matrigel after incubation for 12 h. (C) The quantification result of HUVECs migration (n = 3). (D) The quantification result of HUVECs tube formation (n = 3). *** p < 0.001, **** p < 0.0001.

There was an error in the “2.2. Synthesis and Characterization of BG/Ce-BG” section, where the sentence now reading “Ce-BG was comprised of 75SiO₂-5P₂O₅-(20-m)CaO-mCeO₂ in mol% (m = 0, 2 or 5), named as 0 Ce-BG, 2 Ce-BG and 5 Ce-BG, respectively.” previously said “75SiO₂-5P₂O₅-(15-m)CaO-mCeO₂”.

There was an error in the “2.9. In Vivo Wound Healing in a Diabetic Skin Defect Model” section, where the sentence now reading “The skin of wounds were treated with five groups as the gauze (C, control), GelMA (G), 0 Ce-BG/GelMA (0/G), 5 Ce-BG/GelMA (5/G).” previously said “0 Ce-BG/GelMA (0/G), 2 Ce-BG/GelMA (2/G), 5 Ce-BG/GelMA (5/G)”.

There was an error in the “3.6. The Wound Healing Effects on Diabetic Skin Defect Model In Vivo” section, where the sentence now reading “The wound closure time in groups of 0/G and 5/G were faster than the G and control groups, especially in the 5/G group.” previously said “0/G, 2/G and 5/G”.

The authors apologize for any inconveniences caused and state that the scientific conclusions of the paper are unaffected.
