Abstract
Fat tissue (FT) has been used for many years in regenerative surgery as a bioactive material through the lipofilling/fat graft (F-GRF)-nano-fat technique, as a bioactive scaffold when it was enriched with adipose-derived mesenchymal stem cells (AD-MSCs) contained in the stromal vascular fraction (SVF), and as a direct source of AD-MSCs used in wound healing (WH) and scar treatment (ST). This systematic review aims to describe the advances in FT engineering applied to regenerative surgery (from bench to clinic), through the use of AD-MSCs, SVF contained in F-GRF in WH and ST. The work has been performed by assessing in the selected studies autologous graft of AD-MSCs, SVF, and F-GRF compared to any control for ST and WH. The protocol was developed following the Preferred Reporting for Items for Systematic Reviews and Meta-Analyses-Protocols (PRISMA-P) guidelines. A multistep search of the PubMed, MEDLINE, Embase, PreMEDLINE, Ebase, CINAHL, PsycINFO, Clinicaltrials.gov , Scopus database, and Cochrane databases has been performed to identify papers on AD-MSCs, SVF, and F-GRF use in WH and ST in which FT was used as bioactive material-scaffold and source of AD-MSCs. Of the 714 articles initially identified, 453 articles focusing on regenerative strategies in WH and ST were selected and, consequently, only 84 articles that apparently related to AD-MSC, SVF, and F-GRF were analyzed. Of these, 61 articles identified as pre-clinical, experimental, and in vitro, and 5 articles identified as a comment and systematic review were excluded. Only 18 original articles which strictly and exclusively focused on autologous AD-MSCs, SVF, and F-GRF in ST and WH were analyzed. The included studies had to match predetermined criteria according to the PICOS (patients, intervention, comparator, outcomes, and study design) approach. The identified studies described microscopic and clinical outcomes in patients treated with AD-MSCs, SVF, and F-GRF. Collected data confirmed the safety and efficacy of FT both as bioactive material-scaffold and source of AD-MSCs in WH and ST without major side effects.

Abstract
Stem cell therapy has been proved to be an effective approach to ameliorate the heart remodeling post myocardial infarction (MI). However, poor cell engraftment and survival in ischemic myocardium limits the successful use of cellular therapy for treating MI. Here, we sought to transplant adipose derived-mesenchymal stem cells (AD-MSCs) with a hydrogel (NapFF-NO), naphthalene covalently conjugated a short peptide, FFGGG, and β-galactose caged nitric oxide (NO) donor, which can release NO molecule in response to β-galactosidase. AD-MSCs, either from transgenic mice that constitutively express GFP and firefly luciferase (Fluc), or express Fluc under the control of VEGFR2 promoter, were co-transplanted with NapFF-NO hydrogel into murine MI models. Improved cell survival and enhanced cardiac function were confirmed by bioluminescence imaging (BLI) and echocardiogram respectively. Moreover, increasing VEGFR2-luc expression was also tracked in real-time in vivo, indicating NapFF-NO hydrogel stimulated VEGF secretion of AD-MSCs. To investigate the therapeutic mechanism of NapFF-NO hydrogel, cell migration assay, paracrine action of AD-MSCs, and histology analysis were carried out. Our results revealed that condition medium from AD-MSCs cultured with NapFF-NO hydrogel could promote endothelial cell migration. Additionally, AD-MSCs showed significant improvement secretion of angiogenic factors VEGF and SDF-1α in the presence of NapFF-NO hydrogel. Finally, postmortem analysis confirmed that transplanted AD-MSCs with NapFF-NO hydrogel could ameliorate heart function by promoting angiogenesis and attenuating ventricular remodeling. In conclusion, NapFF-NO hydrogel can obviously improve therapeutic efficacy of AD-MSCs for MI by increasing cell engraftment and angiogenic paracrine action.
