The search for tissue regeneration has attracted a lot of attention due to its wide applicability, and great potential to solve several problems in advanced therapies. Currently, functional systems have been widely used as therapeutic solutions in the treatment of some skin diseases, whether chronic, acquired, or as a consequence of accidents and burns. It is possible due to the feasibility of releasing and/or acting in loco of some active substances with properties and characteristics very similar to human skin. In this sense, this work aimed to carry out a literature review research regarding the development of new biomaterials, including hydrated membranes composed of biopolymers such as keratin and bacterial cellulose.

ABSTRACT Tooth losses due to pathological processes continue to be a reality in daily clinical dentistry, inducing functional and psychological complications in patients. In view of this, a new option for the management of this problem - tissue engineering - has been studied in Dentistry. This field, considered multidisciplinary, uses three key elements for tissue regeneration: scaffolds (extracellular matrices) - natural or synthetic; cells, and growth factors. In this sense, combination of these three elements may induce regeneration of the dental pulp, bone and periodontal tissue, among others. Therefore, the aim of this study was to conduct a literature review, describing the main elements of tissue engineering and their applicability in Dentistry, as a means of updating dental surgeons about this subject.

ABSTRACTTissue engineering scaffolding is the external media or structure in which cell growth, migration and reproduction is enabled in order to stimulate tissue regeneration. In order to promote tissue regeneration, scaffolding materials are required to have certain properties such as biocompatibility, adequate mechanical properties and surface topographical features in order to provide specific biological signals to promote cell attachment and proliferation [1].Cellulose is the most abundant, inexpensive and readily available carbohydrate polymer in the world and it is traditionally extracted from plants or their wastes [2]. Although the plant itself is the major contributor of cellulose, various types of bacteria are able to produce cellulose and it is termed bacterial cellulose [3]. Bacterial cellulose is a well suited scaffold for tissue regeneration due to its biocompatibility, mechanical properties and its ability to be combined with other structures such calcium phosphates [4], which can create composites with intrinsic properties that meet the requirements of the different tissues of the human body [5].Through additive manufacturing, highly complex structures can be created which are similar to those found in nature. This work will explore the different ways to produce biomimetic structures for tissue engineering applications through the combination of bacterial cellulose and additive manufacturing producing complex structures of a highly a biocompatible material for a range of different biomedical applications [6]. In addition to the manufacturing and processing techniques, the use of mango (juice/peel) as a complex carbon source for the production of bacterial cellulose was investigated.

Large Bone

Bone possesses an intrinsic regenerative capacity, which can be compromised by aging, disease, trauma, and iatrogenesis (e.g. tumor resection, pharmacological). At present, autografts and allografts are the principal biological treatments available to replace large bone segments, but both entail several limitations that reduce wider use and consistent success. The use of decellularized extracellular matrices (ECM), often derived from xenogeneic sources, has been shown to favorably influence the immune response to injury and promote site-appropriate tissue regeneration. Decellularized bone ECM (dbECM), utilized in several forms — whole organ, particles, hydrogels — has shown promise in both in vitro and in vivo animal studies to promote osteogenic differentiation of stem/progenitor cells and enhance bone regeneration. However, dbECM has yet to be investigated in clinical studies, which are needed to determine the relative efficacy of this emerging biomaterial as compared with established treatments. This mini-review highlights the recent exploration of dbECM as a biomaterial for skeletal tissue engineering and considers modifications on its future use to more consistently promote bone regeneration.

The goals of periodontal therapy are to arrest of periodontal disease progression and to attain the regeneration of the periodontal apparatus. Osseous grafting and Guided tissue regeneration (GTR) are the two techniques with the most extensive documentation of periodontal regeneration. However, these techniques offer limited potential towards regenerating the periodontal tissues. Recent surgical procedures and application of newer materials aim at greater and more predictable regeneration with the concept of tissue engineering for enhanced periodontal regeneration and functional attachment have been developed, analyzed, and employed in clinical practice

In the past decade, a new frontier in scarless wound healing has arisen because of significant advances in the field of wound healing realised by incorporating emerging concepts from mechanobiology and immunology. The complete integumentary organ system (IOS) regeneration and scarless wound healing mechanism, which occurs in specific species, body sites and developmental stages, clearly shows that mechanical stress signals and immune responses play important roles in determining the wound healing mode. Advances in tissue engineering technology have led to the production of novel human skin equivalents and organoids that reproduce cell–cell interactions with tissue-scale tensional homeostasis, and enable us to evaluate skin tissue morphology, functionality, drug response and wound healing. This breakthrough in tissue engineering has the potential to accelerate the understanding of wound healing control mechanisms through complex mechanobiological and immunological interactions. In this review, we present an overview of recent studies of biomechanical and immunological wound healing and tissue remodelling mechanisms through comparisons of species- and developmental stage-dependent wound healing mechanisms. We also discuss the possibility of elucidating the control mechanism of wound healing involving mechanobiological and immunological interaction by using next-generation human skin equivalents.

The Impact

In contemporary bioanalysis, monitoring the antioxidant activity (AOA) of the human skin is used to assess stresses, nutrition, cosmetics, and certain skin diseases. Non-invasive methods for skin AOA monitoring have certain advantages over invasive methods, namely cost-effectiveness, lower labor intensity, reduced risk of infection, and obtaining results in the real-time mode. This study presents a new flexible potentiometric sensor system (FPSS) for non-invasive determination of the human skin AOA, which is based on flexible film electrodes (FFEs) and membrane containing a mediator ([Fe(CN)6]3–/4–). Low-cost available materials and scalable technologies were used for FFEs manufacturing. The indicator FFE was fabricated based on polyethylene terephthalate (PET) film and carbon veil (CV) by single-sided hot lamination. The reference FFE was fabricated based on PET film and silver paint by using screen printing, which was followed by the electrodeposition of precipitate containing a mixture of silver chloride and silver ferricyanide (SCSF). The three-electrode configuration of the FPSS, including two indicator FFEs (CV/PET) and one reference FFE (SCSF/Ag/PET), has been successfully used for measuring the skin AOA and evaluating the impact of phytocosmetic products. FPSS provides reproducible (RSD ≤ 7%) and accurate (recovery of antioxidants is almost 100%) results, which allows forecasting its broad applicability in human skin AOA monitoring as well as for evaluating the effectiveness of topically and orally applied antioxidants.

AbstractSkin is the body’s first barrier against external pathogens that maintains the homeostasis of the body. Any serious damage to the skin could have an impact on human health and quality of life. Tissue engineering aims to improve the quality of damaged tissue regeneration. One of the most effective treatments for skin tissue regeneration is to improve angiogenesis during the healing period. Over the last decade, there has been an impressive growth of new potential applications for nanobiomaterials in tissue engineering. Various approaches have been developed to improve the rate and quality of the healing process using angiogenic nanomaterials. In this review, we focused on molecular mechanisms and key factors in angiogenesis, the role of nanobiomaterials in angiogenesis, and scaffold-based tissue engineering approaches for accelerated wound healing based on improved angiogenesis.

In recent years, polyphenols have been extensively studied due to their antioxidant, anticancer, and anti-inflammatory properties. It has been shown that anthocyanins, flavonols, and flavan-3-ols play an important role in the prevention of bacterial infections, as well as vascular or skin diseases. Particularly, resveratrol, as a multi-potent agent, may prevent or mitigate the effects of oxidative stress. As the largest organ of the human body, skin is an extremely desirable target for the possible delivery of active substances. The transdermal route of administration of active compounds shows many advantages, including avoidance of gastrointestinal irritation and the first-pass effect. Moreover, it is non-invasive and can be self-administered. However, this delivery is limited, mainly due to the need to overpassing the stratum corneum, the possible decomposition of the substances in contact with the skin surface or in the deeper layers thereof. In addition, using resveratrol for topical and transdermal delivery faces the problems of its low solubility and poor stability. To overcome this, novel systems of delivery are being developed for the effective transport of resveratrol across the skin. Carriers in the micro and nano size were demonstrated to be more efficient for safe and faster topical and transdermal delivery of active substances. The present review aimed to discuss the role of resveratrol in the treatment of skin abnormalities with a special emphasis on technologies enhancing transdermal delivery of resveratrol.
