    Abstract Background: Wound healing is a complex process including hemostasis, inflammation, proliferation, and remodeling during which an orchestrated array of biological and molecular events occurs to promote skin regeneration. Abnormalities in each step of the wound healing process lead to reparative rather than regenerative responses, thereby driving the formation of cutaneous scar. Patients suffering from scars represent serious health problems such as contractures, functional and esthetic concerns as well as painful, thick, and itchy complications, which generally decrease the quality of life and impose high medical costs. Therefore, therapies reducing cutaneous scarring are necessary to improve patients' rehabilitation.
    Summary: Current approaches to remove scars, including surgical and nonsurgical methods, are not efficient enough, which is in principle due to our limited knowledge about underlying mechanisms of pathological as well as the physiological wound healing process. Thus, therapeutic interventions focused on basic science including genetic and epigenetic knowledge are recently taken into consideration as promising approaches for scar management since they have the potential to provide targeted therapies and improve the conventional treatments as well as present opportunities for combination therapy. In this review, we highlight the recent advances in skin regenerative medicine through genetic and epigenetic approaches to achieve novel insights for the development of safe, efficient, and reproducible therapies and discuss promising approaches for scar management.
    Key message: Genetic and epigenetic regulatory switches are promising targets for scar management, provided the associated challenges are to be addressed.

    Abstract Inflammatory and autoimmune diseases are among the most challenging disorders for health care professionals that require systemic immune suppression which associates with various side effects. Mesenchymal stromal cells (MSCs) are capable of regulating immune responses, mainly through paracrine effects and cell-cell contact. Since MSCs are advanced therapy medicinal products (ATMPs), they must follow Good Manufacturing Practice (GMP) regulations to ensure their safety and efficacy. In this study, we evaluated the immunomodulatory effects of GMP-compliant clinical grade MSCs obtained from four different sources (bone marrow, adipose tissue, Wharton's Jelly, and decidua tissue) on allogeneic peripheral blood mononuclear cells (PBMCs). Our results revealed that WJ-MSCs were the most successful group in inhibiting PBMC proliferation as confirmed by BrdU analysis. Moreover, WJ-MSCs were the strongest group in enhancing the regulatory T cell population of PBMCs. WJ-MSCs also had the highest secretory profile of prostaglandin E2 (PGE-2), anti-inflammatory cytokine, while interleukin-10 (IL-10) secretion was highest in the DS-MSC group. DS-MSCs also had the lowest secretion of IL-12 and IL-17 inflammatory cytokines. Transcriptome analysis revealed that WJ-MSCs had the lowest expression of IL-6, while DS-MSCs were the most potent group in the expression of immunomodulatory factors such as hepatocyte growth factor (HGF) and transforming growth factor-β (TGF- β). Taken together, our results indicated that GMP-compliant Wharton's Jelly and decidua-derived MSCs showed the best immunomodulatory performance considering paracrine factors.

    Abstract Wound healing remains a burdensome healthcare problem due to moisture loss and bacterial infection. Advanced hydrogel dressings can help to resolve these issues by assisting and accelerating regenerative processes such as cell migration and angiogenesis because of the similarities between their composition and structure with natural skin. In this study, we aimed to develop a keratin-based hydrogel dressing and investigate the impact of the delivery of LL-37 antimicrobial peptide using this hydrogel in treating full-thickness rat wounds. Therefore, oxidized (keratose) and reduced (kerateine) keratins were utilized to prepare 10% (w/v) hydrogels with different ratios of keratose and kerateine. The mechanical properties of these hydrogels with compressive modulus of 6-32 kPa and tan δ <1 render them suitable for wound healing applications. Also, sustained release of LL-37 from the keratin hydrogel was achieved, which can lead to superior wound healing.

    Abstract Worldwide, impaired wound healing leads to a large burden of morbidity and mortality. Current treatments have several limitations. Recently, nanomaterials such as copper nanoparticles (CuNPs) have attracted considerable research interest. Here, we investigated the potential therapeutic effect of various CuNPs concentrations (1 μM, 10 μM, 100 μM, 1 mM, and 10 mM) and sizes (20 nm, 40 nm, 80 nm) in wound healing. Our results revealed that the 10 μM concentration of 40 nm CuNPs and the 1 μM concentration of 80 nm CuNPs were not toxic to the cultured fibroblast, endothelial, and keratinocyte cells, and also 1 μM concentration of 80 nm CuNPs enhanced endothelial cell migration and proliferation. Extensive assessment of in vivo wound healing demonstrated that the 1 μM concentration of 80 nm CuNPs accelerated wound healing over a shorter time via formation of granulation tissue and higher new blood vessels. Importantly, serum biochemical analysis confirmed that the 40 nm CuNP (10 μM) and 80 nm CuNP (1 μM) did not show any accumulation in the liver during wound healing. Overall, our results have indicated that the 1 μM concentration of 80 nm CuNPs is a promising NP for wound healing applications without adverse side effects.

    Abstract Aim: The aim of this study was to determine gene expression levels of TNF-α, NOTCH1, and HES1 in patients with UC.
    Background: Intestinal inflammation and epithelial injury are the leading actors of inflammatory bowel disease (IBD), causing an excessive expression of pro-inflammatory cytokines such as TNF-α. Also, target genes of NOTCH signaling are involved in the regulation of intestinal homeostasis. Previous studies have demonstrated that TNF-α increases in ulcerative colitis (UC) patients, but the relationship between TNF-α and NOTCH signaling pathway in UC etiopathology needs further study.
    Methods: Twelve active UC patients and twelve healthy controls were enrolled in this study. RNA was extracted and the mRNA expression levels of TNF-α, NOTCH1, and HES1 were examined using real-time PCR analyses. Further, transcriptome data deposited in Gene Expression Omnibus (GEO) database were analyzed to detect the differential expression of TNF superfamily and NOTCH1 gene in IBD patients. Finally, the interaction of TNF-α and NOTCH signaling was obtained from The SIGnaling Network Open Resource 2.0 (SIGNOR 2.0) database.
    Results: The transcription levels of TNF-α, NOTCH1, and HES1 genes were significantly elevated in UC patients compared with control (p < 0.05). In addition, GEO results confirmed our expression results. SIGNOR analysis showed that TNF-α interacts with NOTCH signaling components.
    Conclusion: Based on our data, we observed that NOTCH1 and HES1 in co-operation of TNF-α, may play an important role in pathogenesis of UC. The members of NOTCH signaling pathway can be ideal candidates to target the therapy of IBD.

    Abstract Objective: Autologous transplantation of epidermal cells has been used increasingly to treat vitiligo patients and is a simple, safe, and relatively efficient method. However, the outcome is not always satisfactory, and some patients show less or no response to this treatment. This study was evaluated to identify genes expressed differently among responders and non-responders to cell transplantation to find potential markers that could predict 'patients' responses to this type of cell therapy.
    Materials and methods: Eleven stable vitiligo patients who received autologous epidermal cell transplantation were included in this clinical trial study. Before cell transplantation, skin samples were obtained from the recipient's vitiligo lesions. After epidermal cell transplantation, patients were followed for at least six months to assess the response to epidermal cell injection. RNA sequencing was used to determine potential gene expression profile differences between responder and non-responder vitiligo patients.
    Results: The RNA sequencing results showed differences in expression levels of 470 genes between the skin specimens of responder versus non-responder patients. There were 269 up-regulated genes and 201 down-regulated genes. Upregulated genes were involved in processes, such as Fatty Acid Omega Oxidation. Down-regulated genes were related to PPAR signaling pathway, and estrogen signaling pathway. Among the most differentially expressed genes (DEGs) with the most altered RNA expression levels in responders versus non-responder patients, we selected three genes (up-regulated genes
    Conclusion: Based on our findings, it is estimated that proposed genes might predict the response of vitiligo patients to cell therapy. However, further studies are required to clarify the role of these genes in pathogenesis and to characterize gene expression in a larger number of vitiligo patients in the context of epidermal cell transplantation therapy (registration number: IRCT201508201031N16).

    Abstract Billions of dollars are annually invested in pharmaceutical industry and cosmetic sector with intent to develop new drugs and treatment strategies for alopecia. Because the hair looks an important characteristic of humans-an effective appendage in perception, expression of beauty, and preservation of self-esteem-the global market for hair loss treatment products is exponentially increasing. However, current methods to treat hair loss endure yet multiple challenges, such as unfavorable outcomes, nonpermanent and patient-dependent results, as well as unpredictable impacts, which limit their application. Over recent years, remarkable advances in the fields of regenerative medicine and hair tissue engineering have raised new hopes for introducing novel cell-based approaches to treat hair loss. Through cell-based approaches, it is possible to produce hair-like structures in the laboratory setting or manipulate cells in their native niche (in vivo lineage reprogramming) to reconstruct the hair follicle. However, challenging issues still exist with the functionality of cultured human hair cells, the proper selection of nonhair cell sources in cases of shortage of donor hair, and the development of defined culture conditions. Moreover, in the case of in vivo lineage reprogramming, selecting appropriate induction factors and their efficient delivery to guide resident cells into a hair fate-with the aim of reconstructing functional hair-still needs further explorations. In this study, we highlight recent advances and current challenges in hair loss treatment using cell-based approaches and provide novel insights for crucial steps, which must be taken into account to develop reproducible, safe, and efficient cell-based treatment.
