Corrigendum to “Chitosan nanoparticle loaded by epidermal growth factor as a potential protein carrier for wound healing: In vitro and in vivo studies”

Abstract

[Montazeri, S., et al.: Chitosan nanoparticle loaded by epidermal growth factor as a potential protein carrier for wound healing: in vitro and in vivo studies. IET Nanobiotechnol. 17(3), 204–211 (2023). https://doi.org/10.1049/nbt2.12116]

In Section 2.9 [In vivo wound healing study], the statement “In the present study, 20 mature Sprague-Dawley rats weighing 200–300 g were used” was incorrect. This should have read: “In the present study, 25 mature Sprague-Dawley rats weighing 200–300 g were used.”

In Section 2.9 [In vivo wound healing study], the statement “The treatment started on day 0, wound dressing of each group was changed every day until the 14th day.” Was missing and is now included in the paragraph.

In Section 2.9 [In vivo wound healing study], the ethical approval statement was missing. The statement has now been provided below:

“All animal experiments in this study were performed with the approval of the Animal Ethics Committee of the Avicenna Research Institute under reference number IR.ACECR.Avicenna.REC.1396.19.”

In Section 2.10 [Wound histological analysis], the statement “After 14 days, the animals were sacrificed by spinal cord injury under anaesthesia” was incorrect. This should have read: “After 14 days, the animals were euthanized using carbon dioxide (CO₂).”

In Table 1, the standard deviation (SD) values were missing. The correct version of the table [with the SD values] is provided below:

The quality of the images in Figure 5a was inadvertently altered and decreased during the preparation and publication process. They have been replaced with images of higher quality.

The conclusions reached within the study remain unaffected. The authors apologize for these errors.
