Scalds and cuts are common causes of childhood injuries at home. Although the impairments are often non-fatal, timely and effective treatments for them may not only help prevent infections, but also facilitate faster recovery from the injuries and scarless wound healing. Skin growth factors including the 53-amino acid human epidermal growth factor (EGF) and the 146-amino acid human basic fibroblast growth factor (bFGF) have been shown to play important physiological functions in promoting the growth and regeneration of our skin cells. Moreover, they have been employed individually to enhance the healing process of various types of wound. The specific bioactivities exhibited by EGF and bFGF in the epidermal and dermal layers, respectively, strongly support the notion that they may function cooperatively in wound healing. In this communication, making use of our own recombinant EGF (rEGF) and bFGF (rbFGF) products, which share the same primary structures with their native counterparts, we present research findings to demonstrate that rEGF and rbFGF work collaboratively to promote healing of various types of wound, including scalds, punctures and lacerations. More importantly, despite the severity of the injuries, subsequent to their treatments with rEGF and rbFGF, the healed wounds were virtually scar-free and devoid of the formation of an outgrowth scar, a keloid scar.

Ischemic wounds are the most severe expression of critical limb ischemia (CLI), and they have been defined clinically as an end stage of peripheral arterial disease. Urgent revascularization is a fundamental part for limb salvage in patients with CLI. However, the risk of revascularization should be weighed against the likelihood of success given a patient’s life-threatening comorbidities. Once the condition of arterial insufficiency is revascularized, wound care is an important aspect to promote the wound healing process and infection control. MOIST concept for wound care is a modern systematic treatment for enhanced wound healing process. Currently, advanced biological therapies are emerging in ischemic wound therapies to restore the wound healing process and involve active biological agents to support the wound healing process. We studied and summarized the different types of available topical biological therapies and their mechanisms on the healing process including platelet-derived growth factor, epidermal growth factor, fibroblast growth factor, and vascular endothelial growth factor, platelet-rich plasma, and honey for local wound care of patient with CLI. Our review suggests that topical platelet-derived growth factor, epidermal growth factor, platelet-rich plasma, and honey are available as well as considered in the ischemic wound healing process enhancement through the MOIST concept. In conclusion, biologic wound dressing or topical agent therapy may improve the wound healing process, increase limb salvage, is inexpensive, and provides potential safety with nontoxic low-risk therapy in patients with an ischemic wound. Thus, local wound care by biological dressing should be added in adjuvant treatment for ischemic wound patients. However, further randomized studies are needed to support efficacy and long-term outcomes of these biological dressing in patients with ischemic wound.

Background: Wounds occur when normal skin structures are damaged. Injury events in Indonesia have increased by 8.2% and the highest prevalence in South Sulawesi is 12.8%. One of the growth factors that play a role in the wound healing process is epidermal growth factor (EGF). EGF includes polypeptides that contain 53 amino acids, and EGF is present in all fluids in the body and platelets. This review aims to determine the role of EGF in the process of wound healing. Method: Data collected since 2017 using 8 databases (pubmed, science direct, google schollar) where the literature used is internationally published literature, additional references are taken from the bibliography of all relevant articles, all relevant articles are reviewed and analyzed. Results: EGF has a role in wound healing. EGF increases motility and epithelial cell migration. EGF can stimulate cell growth, proliferation and differentiation by binding to high affinity to the EGF receptor (EGFR) on the cell surface. The goal of EGF healing is most epithelial tissue, fibroblasts, and endothelial cells. EGF can call three important biological actions in tissue repair including cytoprotection, mitogenesis, and migration. Conclusion: EGF plays an important role in the wound healing process, especially in the re-epithelial process. Based on this review, it is suggested that the selection of dressings that are used should support EGF.

We propose a reaction-diffusion model of the mechanisms involved in the healing of corneal surface wounds. The model focuses on the stimulus for increased mitotic and migratory activity, specifically the role of epidermal growth factor. We determine an analytic approximation for the speed of travelling wave solutions of the model in terms of the parameters and verify the results numerically. By comparing the predicted speed with experimentally measured healing rates, we conclude that serum-derived factors can alone account for the overall features of the healing process, but that the supply of growth factors by the tear film, in the absence of serum-derived factors, is not sufficient to give the observed healing rate. Numerical solutions of the model equations also confirm the importance of both migration and mitosis for effective wound healing. By modifying the model, we obtain an analytic prediction for the healing rate of corneal surface wounds when epidermal growth factor is applied topically to the wound.

Our previous study has demonstrated that epidermal growth factor (EGF) with tocotrienol-rich fraction (TRF) cream formulation accelerating postburn wound healing with deep partial-thickness burn in rats. Current study was conducted to determine the gene expression levels related to burn wound healing process. A total of 180 Sprague-Dawley rats were randomly divided into 6 groups: untreated control, treated with Silverdin cream, base cream, base cream with 0.00075% EGF, base cream with 3% TRF or base cream with 0.00075% EGF, and 3% TRF, respectively. Burn wounds were created and the above-mentioned creams were applied once daily. Six animals from each group were sacrificed on days 3, 7, 11, 14, and 21 postburn. RNA was extracted from wound tissues and quantitative real-time polymerase chain reaction was performed to analyze the 9 wound healing-related genes against time postburn. Results demonstrated that topically applied EGF + TRF formulation downregulated the expression levels of IL-6 ( interluekin-6), TNF-α ( tumor necrosis factor-α) and iNOS ( inducible nitric oxide synthase) throughout the whole healing process. TGF-β1 ( transforming growth factor-β) and VEGF-A ( vascular endothelial growth factor-A) were reduced on day 14 postburn. On the contrary, increased expression of Collagen-1 in the early stage of wound healing was observed with no effects on epidemal growth factor receptor (EGFR). The results showed beneficial application of EGF + TRF cream in the treatment of burn wound since it accelerated wound healing by relieving oxidative stress, decreasing inflammation, and promoting proper tissue modelling in the burn wound.

An analysis of modern scientific and practical literature leaves no doubt that among the many problems of a dentist, an important place is occupied by the optimization of wound healing of the oral mucosa in case of injuries. Immunodeficiencies of various origins, elderly and senile age, diabetes mellitus, and severe pathology of the cardiovascular system, hypoxic conditions and other somatic diseases reduce the repair potential of the oral mucosa. In addition, all types of metabolism are disrupted, synthesis and humoral transport are reduced, as well as the secretion of growth factors with saliva and their content in the blood and tissue. The healing process of the oral mucosa is slowed down by bacterial colonization of the wound surface, which can increase the area of inflammation. A common method of treating such patients in a dental clinic is the use of agents aimed at regenerative processes in tissues. Along with the positive qualities of modern drugs (good fixation, comfort when used in the oral cavity, wound healing, bactericidal effect on the damaged mucous membrane, reducing pain, accelerating the processes of epithelialization and scar organization), a noticeable weakening of their action in immunodeficient conditions should be noted. Based on this, it is advisable to use recombinant epidermal growth factor (EGFR) in the treatment of traumatic lesions of the oral mucosa, including those caused by the use of orthopedic structures, surgical interventions, especially those accompanied by conditions involving a decrease in the immune status.

Growth Factor Production

Patients with diabetes experience impaired growth factor production such as epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF), and they are reportedly involved in wound healing processes. Here, we report dual growth factor-loaded hyaluronate collagen dressing (Dual-HCD) matrix, using different ratios of the concentration of stabilized growth factors—stabilized-EGF (S-EGF) and stabilized-bFGF (S-bFGF). At first, the optimal concentration ratio of S-EGF to S-bFGF in the Dual-HCD matrix is determined to be 1:2 in type I diabetic mice. This Dual-HCD matrix does not cause cytotoxicity and can be used in vivo. The wound-healing effect of this matrix is confirmed in type II diabetic mice. Dual HCD enhances angiogenesis which promotes wound healing and thus, it shows a significantly greater synergistic effect than the HCD matrix loaded with a single growth factor. Overall, we conclude that the Dual-HCD matrix represents an effective therapeutic agent for impaired diabetic wound healing.
