Hyaluronic acid (HA) has been known to play an important role in wound healing process. However, the effect of molecular weight (MW) of exogenously administered HA on the wound healing process has not been fully understood. In this study, we investigated HA with different MWs on wound healing process using human epidermal keratinocytes and dermal fibroblasts. Cell proliferation and migration ability were assessed by water soluble tetrazolium (WST) assay and wound scratch assay. We examined the effect of HA addition in a full-thickness wound model in mice and the gene expression related to wound healing. Proliferation and migration of HaCaT cells increased with the increase of MW and concentration of HA. Interleukin (IL-1β), IL-8 and vascular endothelial growth factor (VEGF) as well as matrix metalloproteinase (MMP)-9 and MMP-13 were significantly upregulated by high molecular weight (HMW) HA in keratinocytes. Together with VEGF upregulation and the observed promotion of HaCaT migration, HA with the MW of 2290 kDa may hold potential to improve re-epithelialization, a critical obstacle to heal chronic wounds.

Abstract Background Long noncoding RNAs (lncRNAs) have been reported to be associated with dermis process during burn wound healing. This study aimed to investigate the role of lncRNA X-inactive specific transcript (XIST) in human skin fibroblasts (HSF) and extracellular matrix (ECM) as well as the regulatory network of XIST/microRNA-29b-3p (miR-29b-3p)/collagen 1 alpha 1 (COL1A1). Methods The wound samples were collected from 25 patients with deep partial thickness burn at day 5 after burn. The thermal injured model was established using HSF cells. The expressions of XIST, miR-29b-3p and COL1A1 were measured by quantitative real-time polymerase chain reaction and western blot. ECM synthesis, cell proliferation and migration were detected by western blot, cell counting kit-8 and trans-well assays, respectively. The interaction between miR-29b-3p and XIST or COL1A1 was explored by bioinformatics analysis and luciferase reporter assay. Results The expressions of XIST and COL1A1 were enhanced but miR-29b-3p expression was decreased after thermal injury. XIST overexpression promoted ECM synthesis, cell proliferation and migration in thermal injured HSF cells. However, XIST knockdown played an opposite effect. miR-29b-3p overexpression inhibited ECM synthesis, cell proliferation and migration, which was reversed by XIST. COL1A1 silence suppressed ECM synthesis, cell proliferation and migration by miR-29b-3p targeting. Moreover, COL1A1 up-regulation weakened the effect of XIST silence on ECM synthesis and HSF cell function. Conclusion XIST promoted ECM synthesis, cell proliferation and migration by sponging miR-29b-3p and targeting COL1A1 in HSF cells after thermal injury, indicating the promoting role of XIST in wound healing.

Non-healing chronic wounds are the key concern in type-2 diabetes that frequently leads to chronic infections, finally causing amputation of limbs, organs etc. Decrease in the proliferation and migration of cells such as keratinocytes and fibroblasts is the major reason for the development of such chronic diabetic wounds. Multiple evidences have shown that CTGF and reduced graphene oxide possesses angiogenic property and promote wound healing by promoting proliferation and migration of fibroblasts and keratinocytes cells.Conjugation of rGO with CTGF using EDC-NHS chemistry is a novel approach to accelerate the wound healing process. In the current work, we have developed a rGO/CTGF incorporated GelMA hydrogel dressing to improve wound healing by increasing proliferation and migration of cells as well as promoting formation of new blood vessels for increased supply of nutrients, oxygen and growth factors to wound area

The delayed and impaired wound healing caused by dexamethasone (DEX) is commonly reported. Puerarin, the major isoflavone found in Pueraria montana var. lobata (Willd.) Sanjappa & Pradeep promoted the wound healing process in diabetic rats. However, the effects and underlying mechanisms of puerarin on DEX-impaired wound healing have not been investigated. This study examined the potential uses of puerarin in upregulating keratinocyte proliferation and migration in dexamethasone (DEX)-suppressed wound healing model. The effects of puerarin on wound healing in vivo were investigated by taking full-thickness 5 mm punch biopsies from the dorsal skin of BALB/c mice and then treating them topically with 0.1% DEX. For the in vitro study, DEX-treated HaCaT cells were used to examine the effects of puerarin on DEX-induced keratinocyte proliferation and migration and the mechanisms of its action. Puerarin, when applied topically, accelerated the wound closure rate, increased the density of the capillaries, and upregulated the level of collagen fibers and TGF-β in the wound sites compared to the DEX-treated mice. Puerarin promoted the proliferation and migration of keratinocytes by activating the ERK and Akt signaling pathways in DEX-treated HaCaT cells. In conclusion, puerarin could be effective in reversing delayed and disrupted wound healing associated with DEX treatments.

Background: One of the main reasons of failure in surgical treatment of primary acquired nasolacrimal duct obstruction is excessive postoperative scarring of the dacryostomy. Despite the variety of procedures designed to prevent this, conflicting evidence of their efficacy and safety provide incentive for further research of antifibrotic therapeutics for adjunctive use in dacryocystorhinostomy.Aims: To evaluate the antifibrotic effect of pirfenidone on human nasal mucosal fibroblast cell culture.Materials and methods: Human nasal mucosal fibroblast cell cultures were established using samples obtained from 3 consecutive patients undergoing endonasal endoscopic dacryocystorhinostomy. Cell viability following treatment with pirfenidone was evaluated using MTS-assay. Induced inhibition of cell proliferation and migration was determined using scratch wound assay.Results: In this study pirfenidone exhibited a significant dose-dependent inhibiting effect on fibroblast proliferation with insignificant cell toxicity. Cell viability following 48 hours of incubation with various pirfenidone concentrations did not drop below 80%. The recovery of the fibroblast monolayer assessed after 24 hours of incubation was 84.88 and 8.26% in the control group, at a drug concentration of 0.15 mg/ml. Cell proliferation and migration was severely inhibited in cell culture specimens treated with pirfenidone compared to controls. The difference between groups was statistically significant (p=0,001).Conclusions: In our study pirfenidone demonstrated a pronounced antifibrotic effect. It is unlikely that inhibition of proliferation and migration of human nasal mucosal fibroblasts is mediated by cell toxicity of this medication as it was evaluated as low. Nonetheless an in vitro analysis is insufficient to judge pirfenidone’s efficacy and safety in preventing cicatrix formation following dacrycystorhinostomy.
