The aqueous extracts of Ganoderma lucidum 1900 (Curtis) P. Karst and Crinipellis schevczenkovi 31 Buchalo mycelia were investigated for skin wound healing activity in vivo using the excision wound healing model. The extracts were prepared by mixing of 100 mg of powdered mycelium of both mushrooms with 1 mL of sterile distilled water for injections. White albino mice line FVB/Cg., 3 months of age (male), were used for the study. The rate of wound healing and the histology of healed wounds in mice have been studied. Visual method of wound study and histological investigation of skin tissue showed the presence of wound healing potential of G. lucidum and C. schevczenkovi mycelia. The wound healing process was expressed more active on 3th day in case of topical application of C. schevczenkovi mycelium extract, but on 5th day the wound healing effects of both mushroom extracts were almost at the same level and statistically better then results in the control group. Wounds treated with mycelial extracts were covered completely on the 6th day compared with 8th day in control group. Wound healing ability of C. schevczenkovi observed in present investigations for the first time.

AbstractPlasma fibrinogen (F1) and fibronectin (pFN) polymerize to form a fibrin clot that is both a hemostatic and provisional matrix for wound healing. About 90% of plasma F1 has a homodimeric pair of γ chains (γγF1) and 10% has a heterodimeric pair of γ and more acidic γ’ chains (γγ’F1). We have synthesized a novel fibrin matrix exclusively from a 1:1 (molar ratio) complex of γγ’F1 and pFN in the presence of highly active thrombin and recombinant Factor XIII (rFXIIIa). In this matrix, the fibrin nanofibers were wrapped with periodic 200-300 nm wide pFN nanobands (termed γγ’F1:pFN fibrin). In contrast, fibrin made from 1:1 mixture of γγF1 and pFN formed a sporadic distribution of “pFN droplets” (termed γγF1 +pFN fibrin). The γγ’F1:pFN fibrin enhanced the adhesion of primary human umbilical vein endothelium cells (HUVECs) relative to the γγF1+FN fibrin. Three dimensional (3D) culturing showed that the γγ’F1:pFN complex fibrin matrix enhanced the proliferation of both HUVECs and primary human fibroblasts. HUVECs in the 3D γγ’F1:pFN fibrin exhibited a starkly enhanced vascular morphogenesis while an apoptotic growth profile was observed in the γγF1 +pFN fibrin. Relative to γγF1 +pFN fibrin, mouse dermal wounds that were sealed by γγ’F1:pFN fibrin exhibited accelerated and enhanced healing. This study suggests that a 3D pFN nano-array presented on a fibrin matrix can promote wound healing.

Abstract Digitaria ciliaris is widely reported to be a problematic weed in agricultural areas and is mainly used as an indicator plant for the development of herbicides. However, its bioactivities on skin regeneration and wound healing have not been investigated. In the present study, we investigated the effects of D. ciliaris flower absolute on skin wound healing and skin regeneration-related events, that is, proliferation, migration, and collagen biosynthesis, in human fibroblasts and keratinocytes. For this study, we extracted absolute from the D. ciliaris flower by solvent extraction and identified the composition of D. ciliaris flower absolute using GC/MS analysis. We also tested the effect of D. ciliaris flower absolute in CCD986sk fibroblasts and/or HaCaT keratinocytes using the WST assay and 5-bromo-2′-deoxyuridine incorporation assay, Boyden chamber assay, ELISA, sprouting assay, and immunoblotting. GC/MS analysis of D. ciliaris flower absolute revealed that it contained 15 compounds. The absolute increased the proliferations of keratinocytes and fibroblasts and the migration of fibroblasts but did not affect cell viabilities. In addition, it enhanced the syntheses of type I and IV collagen in fibroblasts, but not in keratinocytes. The sprouting assay showed increased sprout outgrowth of fibroblasts. In addition, D. ciliaris flower absolute induced the phosphorylation of extracellular signal-regulated kinase 1/2 and p38 mitogen-activated protein kinase in fibroblasts. These results indicate that D. ciliaris flower absolute may promote skin wound healing/regeneration by inducing the proliferation, migration, and collagen synthesis of fibroblasts, as well as the proliferation of keratinocytes. Therefore, D. ciliaris flower absolute may be a potential natural source for cosmetic or pharmaceutical agents that promote skin wound healing/regeneration.

Auricularia auricula-judae, a nutrient-rich mushroom used in traditional medicine, is a macrofungi that exhibits various biological properties. In this study, we have reported on the mechanisms that promote the wound-healing effects of a water-soluble polysaccharide-rich extract obtained from A. auricula-judae (AAP). AAP contained high amounts of polysaccharides (349.83 ± 5.00 mg/g extract) with a molecular weight of 158 kDa. The main sugar composition of AAP includes mannose, galactose, and glucose. AAP displayed antioxidant activity in vitro and was able to abort UVB-induced intracellular ROS production in human fibroblasts in cellulo. AAP significantly promoted both fibroblast and keratinocyte proliferation, migration, and invasion, along with augmentation of the wound-healing process by increasing collagen synthesis and decreasing E-cadherin expression (All p < 0.05). Specifically, the AAP significantly accelerated the wound closure in a mice skin wound-healing model on day 9 (2.5%AAP, p = 0.031 vs. control) and day 12 (1% and 2.5%AAP with p = 0.009 and p < 0.001 vs. control, respectively). Overall, our results indicate that the wound-healing activities of AAP can be applied in an AAP-based product for wound management.

Overexpression of reactive oxygen species (ROS) can lead to chronic inflammation, which limits skin wound healing. Therefore, it is of great significance to develop materials that can locally control the adverse reactions caused by excessive ROS. In this research, an ROS-sensitive hydrogel with strong free radical scavenging ability was prepared by introducing the thione (Tk) group into carboxymethyl chitosan (CMCTS) hydrogel. CMCTS hydrogel was cross-linked by NH2-Tk-NH2 agent and loaded curcumin (Cur), which possessed favorable nontoxicity, water absorption, mechanical property, biodegradability, drug release behavior, the M2 phenotype, and inflammatory factor regulating the capacity of macrophages. It is worth noting that Cur@CMCTS-Tk hydrogel can significantly inhibit oxidative damage of human fibroblasts in the H2O2-induced microenvironment and protect their viability by reducing the production of intracellular ROS. In vivo, ROS-removing hydrogel effectively accelerated the process of wound healing and possessed good regenerative properties, including hair follicle formation, promotion of new blood vessel formation, and highly orderly arrangement of collagen fibers in the full-thickness skin burn defect rat model. Hence, we expect that the Cur@CMCTS-Tk hydrogel could be used for wound treatment and tissue regeneration due to the ability to scavenge excess ROS.

The intracellular serine amidase, fatty acid amide hydrolase (FAAH), degrades a heterogeneous family of lipid-derived bioactive molecules that include amides of long-chain fatty acids with taurine [N-acyl-taurines (NATs)]. The physiological functions of the NATs are unknown. Here we show that genetic or pharmacological disruption of FAAH activity accelerates skin wound healing in mice and stimulates motogenesis of human keratinocytes and differentiation of human fibroblasts in primary cultures. Using untargeted and targeted lipidomics strategies, we identify two long-chain saturated NATs—N-tetracosanoyl-taurine [NAT(24:0)] andN-eicosanoyl-taurine [NAT(20:0)]—as primary substrates for FAAH in mouse skin, and show that the levels of these substances sharply decrease at the margins of a freshly inflicted wound to increase again as healing begins. Additionally, we demonstrate that local administration of synthetic NATs accelerates wound closure in mice and stimulates repair-associated responses in primary cultures of human keratinocytes and fibroblasts, through a mechanism that involves tyrosine phosphorylation of the epidermal growth factor receptor and an increase in intracellular calcium levels, under the permissive control of transient receptor potential vanilloid-1 receptors. The results point to FAAH-regulated NAT signaling as an unprecedented lipid-based mechanism of wound-healing control in mammalian skin, which might be targeted for chronic wound therapy.

Wounds within the oral mucosa are known to heal more rapidly than skin wounds. Recent studies suggest that differences in the microRNAome profiles may underlie the exceptional healing that occurs in oral mucosa. Here, we test whether skin wound-healing can be accelerating by increasing the levels of oral mucosa-specific microRNAs. A panel of 57 differentially expressed high expresser microRNAs were identified based on our previously published miR-seq dataset of paired skin and oral mucosal wound-healing [Sci. Rep. (2019) 9:7160]. These microRNAs were further grouped into 5 clusters based on their expression patterns, and their differential expression was confirmed by TaqMan-based quantification of LCM-captured epithelial cells from the wound edges. Of these 5 clusters, Cluster IV (consisting of 8 microRNAs, including miR-31) is most intriguing due to its tissue-specific expression pattern and temporal changes during wound-healing. The in vitro functional assays show that ectopic transfection of miR-31 consistently enhanced keratinocyte proliferation and migration. In vivo, miR-31 mimic treatment led to a statistically significant acceleration of wound closure. Our results demonstrate that wound-healing can be enhanced in skin through the overexpression of microRNAs that are highly expressed in the privileged healing response of the oral mucosa.
