In tissue repair, MSC-Exos are more effective than MSCs, and they can be used as a cell-free alternative therapy to MSCs. This therapeutic system has a stable membrane structure that is coated with proteins, miRNAs, mRNA, lncRNA, DNA, and other macromolecular active substances. These molecules have a powerful effect on tissue regeneration. MSC-Exos can regulate the biological function of target cells through direct recognition, membrane fusion, and secretion of communication mediators. Skin wound healing consists mainly of blood coagulation, inflammation response, cell proliferation, and tissue remodeling. By regulating the four stages of wound healing, MSC-Exos effectively reduce tissue inflammation, reduce the immune response, promote enhanced cell migration and angiogenesis and regulate tissue remodeling, thus shortening the healing time and reducing scar formation. A variety of biological factors, genetic material and signaling pathways are involved in this process. This article reviews the efficacy and mechanism of MSC-Exos in promoting skin tissue repair.</p></div>","PeriodicalId":22019,"journal":{"name":"Smart Materials in Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45255078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the lack of osteogenic activity restricts its application. In this study, gold nanoparticles (GNPs) with excellent osteogenic differentiation ability were incorporated into the network of BC hydrogel (Au/BC hydrogels) by the in-situ fermentation. The effects of GNPs on physicochemical properties of BC hydrogel and subsequently <em>in vitro</em> osteogenic differentiation and <em>in vivo</em> bone regeneration of Au/BC hydrogels were comprehensively investigated. The results showed that the increased feeding amounts of GNPs could remarkablly enhance the Au/BC hydrogels with better mechanical properties, higher porosity, larger surface area, and biocompatibility. The sustainable release of GNPs endowed the hydrogels with an outstanding biological activity in facilitating osteogenic differentiation of human bone marrow-derived mesenchymal stem cells (hBMSCs). Mechanism research showed that autophagy might be a potential pathway for Au/BC hydrogels-induced osteogenic differentiation of hBMSCs. In addition, Au/BC hydrogel exhibited an excellent <em>in vivo</em> bone repair performance in a rabbit model of femoral defect, which was evidenced by the significant newly bone formation. Overall, the multifunctional Au/BC hydrogels fabricated by in-situ fermentation could serve as a good scaffold for promoting bone tissue regeneration in clinic.</p></div>","PeriodicalId":22019,"journal":{"name":"Smart Materials in Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49716760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of nanotubes has been raised due to their excellent mechanical properties, carry and delivery of drugs capabilities, and bioactive properties. These features depend on the composition of nanotubes and their application. This scoping review aims to describe previous studies about incorporating nanotubes in restorative resin-based materials. The main goals here addresses are: (1) to identify which are the most used nanotubes in the development of these dental materials; (2) to verify which the molecules/particles associated with these nanotubes; (3) to report the objectives of the incorporation of nanotubes to these dental materials and main results. The searches were performed using PubMed and Scopus databases in December 2022, identifying 534 manuscripts. After the selection process, 43 studies were included in the review. We mainly analyzed and discussed the nanotubes' composition, the parental materials in which the nanotubes were incorporated, the purposes of adding these particles to the dental materials, how the materials were analyzed, and the primary studies' outcomes. The outcomes are stimulating and reveal a promising advance in dental resins with the possibility of improving the maintenance of restorations and patients' quality of life.

Several million cases of PNI in the world every year have brought a heavy burden to the patients and the social economy. Autologous nerve grafting has long been the “gold standard” in the treatment of PNI repair, but it still has some shortcomings, such as donor area injury, limited graft source and mismatch of nerve thickness after transplantation. In recent years, many artificial nerve guidance conduits (NGCs) have emerged for replacing autologous nerve grafts, and their effectiveness has been proven. Currently, there are already clinical products obtained from the European CE Certification, and approved by the Food and Drug Administration (FDA), China Food and Drug Administration (CFDA), Therapeutic Goods Administration (TGA) in Australia, etc. The preparation of NGCs requires interdisciplinary studies and has received considerable attention from researchers in recent years. At present, among emerging and mature manufacturing technologies, textile methods to prepare NGCs are relatively simple and have wide material sources, which has become a hotspot in textile research.
