Special Issue Information

Dear Colleagues,

The complexity of wound healing and subsequent scarring triggers the need for both basic and translational studies in the field. The prevalence of wound healing impairments boosts the drive to an applicatory approach in the field.

Yet, since numerous physiological and molecular processes are involved in wound healing (e.g. inflammation, fibrosis, cell migration, angiogenesis, matrix remodeling, etc.), there are endless targets for novel therapies. Without deepening the knowledge of the mechanism of wound healing or scarring search for novel, or implementation of preexisting therapies may be hampered. Recent advancements in wound healing research showed increasing importance in deciphering the role of the HIF-1α pathway, along with further studies on certain cytokines like TGF-β IFN-γ. Controversies on macrophage M1/M2 shift and their targeting in wound healing are also addressed with intense research. The role of M2 macrophages and certain cytokines (especially TGF-β and IFN-γ) seems to be pivotal in scar maturation, which if disrupted, may produce hypertrophic scar or keloids. Exploration of these and many other mechanisms is particularly crucial in chronic wounds. Of those, most of the studies focus on diabetic wound healing, due to its challenging nature in management. Also, impaired immunological response, excessive matrix metalloproteinase (MMP) activity, explicit oxidative stress increase, and impaired remodeling lead to prolonged healing and poor scar quality. All of the above are profoundly studied and may pose a target for novel therapies. But for the improvement of the wound healing mechanisms, successful therapies are studied relying on woundbed augmentation with stem cells of different origins. Understanding the mechanism underlying their efficiency may lead to further exciting discoveries.  

Those topics are especially invited for submission in this Special Issue.

Thus, in this Special Issue authors are encouraged to submit papers that fill the gap in the knowledge of wound healing and scarring. Due to the aforementioned nature of the topic, a dual approach is needed for advancement in the fields—experimental use of novel pharmaceuticals or devices (wound dressings) followed by studies concerning exploration of the underlying mechanism of (un)successful therapies.

Articles that aim to contribute to this Special Issue should address the topic via well-designed studies. Papers should concern molecular aspects of wound healing—either in basic research or in. applicatory approach. Relevant and innovative systematic reviews and meta-analyses are also allowed for submission to this Special Issue.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English.

The objective of this study was to investigate if delivering multiple doses of N-acetylcysteine (NAC) post-surgery in addition to pre-incisional administration significantly impacts the wound healing process in a rat model. Full-thickness skin incisions were carried out on the dorsum of 24 Sprague-Dawley rats in six locations. Fifteen minutes prior to the incision, half of the sites were treated with a control solution, with the wounds on the contralateral side treated with solutions containing 0.015%, 0.03% and 0.045% of NAC. In the case of the NAC treated group, further injections were given every 8 h for three days. On days 3, 7, 14 and 60 post-op, rats were sacrificed to gather material for the histological analysis, which included histomorphometry, collagen fiber organization analysis, immunohistochemistry and Abramov scale scoring. It was determined that scars treated with 0.015% NAC had significantly lower reepithelization than the control at day 60 post-op (p = 0.0018). Scars treated with 0.045% NAC had a significantly lower collagen fiber variance compared to 0.015% NAC at day 14 post-op (p = 0.02 and p = 0.04) and a lower mean scar width than the control at day 60 post-op (p = 0.0354 and p = 0.0224). No significant differences in the recruitment of immune cells and histological parameters were found. The results point to a limited efficacy of multiple NAC injections post-surgery in wound healing.
