Hamann A, Pannier AK. Innovative nonviral gene delivery strategies for engineering human mesenchymal stem cell phenotypes toward clinical applications. Curr Opin Biotechnol 2022; 78:102819. [PMID: 36274497 DOI: 10.1016/j.copbio.2022.102819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2022] [Revised: 09/13/2022] [Accepted: 09/15/2022] [Indexed: 12/14/2022]
Abstract
Although human mesenchymal stem cells (hMSCs) have been used in many clinical trials, variable outcomes have resulted in no FDA-approved hMSC treatment. However, research into developing hMSC therapies for many diseases continues. An approach to manipulate hMSCs for therapeutic applications is gene delivery. Nonviral gene delivery is safer and more flexible than viral vectors, but much less efficient, especially in hMSCs. It is not understood why hMSCs are more difficult to transfect than cell lines, but innate features of hMSCs may present unique barriers to transfection. Recently, strategies to improve hMSC transfection have been developed by innovating nanocarriers, nucleic acid cargos, and by 'priming' hMSCs chemically and physically for more efficient transfection. These strategies aim to engineer hMSCs with new phenotypes mediated by transgenic secreted factors, receptors, transcription factors, and genome editing systems for clinical applications requiring enhanced immunomodulation and/or tissue regeneration, or for functions such as tumor-killing and tissue engineering.

Teixeira ABV, Moreira NCS, Takahashi CS, Schiavon MA, Alves OL, Reis AC. Cytotoxic and genotoxic effects in human gingival fibroblast and ions release of endodontic sealers incorporated with nanostructured silver vanadate. J Biomed Mater Res B Appl Biomater 2021; 109:1380-1388. [PMID: 33470054 DOI: 10.1002/jbm.b.34798] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 12/10/2020] [Accepted: 01/09/2021] [Indexed: 01/08/2023]
Abstract
The cytotoxic and genotoxic effects of commercial endodontic sealers (AH Plus, Sealer 26 and Endomethasone N) incorporated with nanostructured silver vanadate decorated with silver nanoparticles (AgVO3 - at concentrations 2.5, 5, and 10%) on human gingival fibroblast (HGF), and the silver (Ag+ ) and vanadium (V4+ /V5+ ) ions release were evaluated. Cytotoxicity, cell death, and genotoxicity tests were carried out with extract samples of 24-hr and 7-days. The release of Ag+ and V4+ /V5+ was evaluated. Cytotoxicity in HGF was caused by AH Plus (AP) with 5 and 10% of AgVO3 (83.84 and 67.49% cell viability, respectively) with 24-hr extract (p < 0.05), as well as all concentrations of AP with 7-days extract (p < 0.05 -AP 0% = 73.17%; AP 2.5% = 75.07%; AP 5% = 70.62%; AP 10% = 68.46% cell viability). The commercial sealers Sealer 26 (S26) and Endomethasone N (EN) were cytotoxic (p < 0.05 - S26 0% = 34.81%; EN 0% = 20.99% cell viability with 7-days extract). AP 10% with 7-days extract induced 32% apoptotic cells in HGF (p < 0.05). Genotoxic effect was not observed. The AP groups released more Ag+ , while S26 and EN released more V4+ /V5+ in 24 hr. The Ag+ can be cytotoxic. In conclusion, the cytotoxicity caused to HGF can be attributed by the commercial sealers and enhanced by incorporation of AgVO3 , was not observed genotoxic effect, and apoptosis was induced only by AH Plus 10% 7-days extract. Ag+ can influence cell viability.

Abstract
Mesenchymal stem/stromal cells (MSC) show widespread application for a variety of clinical conditions; therefore, their use necessitates continuous monitoring of their safety. The risk assessment of mesenchymal stem cell-based therapies cannot be separated from an accurate and deep knowledge of their biological properties and in vitro and in vivo behavior. One of the most relevant safety issues is represented by the genetic stability of MSCs, that can be altered during in vitro manipulation, frequently required before clinical application. MSC genetic stability has the potential to influence the transformation and the therapeutic effect of these cells. At present, karyotype evaluation represents the definitely prevailing assessment of MSC stability, but DNA alterations of smaller size should not be underestimated. This review will focus on current scientific knowledge about the genetic stability of mesenchymal stem cells. The techniques used and possible improvements together with regulatory aspects will also be discussed.

Biological relevance of CuFeO 2 nanoparticles: Antibacterial and anti-inflammatory activity, genotoxicity, DNA and protein interactions. MATERIALS SCIENCE & ENGINEERING.

[PMID: 30889700 DOI: 10.1016/j.msec.2019.01.112] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Revised: 01/23/2019] [Accepted: 01/25/2019] [Indexed: 12/12/2022]
Abstract
Heterometal oxide nanoparticles of bioessential metals are shedding new light to nanoparticle-inspired bioapplications. Pairing bioreactive elements like copper and iron can affect the redox dynamic and biological profile of the nanomaterial. Given the complexity of physicochemical properties, biological activity and toxicity concerns, extensive exploration is demanded, especially when active and less active oxidation states participate as in case of cuprous-ferric delafossite CuFeO2 (copper(I)-iron(III)), a less widespread nanomaterial. In that vein, CuFeO2 nanoparticles were synthesized and biological profile was evaluated in comparison with cuprous oxide (Cu2O NPs) counterpart, an already established antimicrobial agent. Interactions with bacteria, proteins and DNA were examined. Cu2O NPs exhibited stronger antibacterial activity (IC50 < 25 μg/ml) than CuFeO2 NPs (IC50 > 100 μg/ml). In vitro exposure of nanoparticles on plasmid DNA unveiled toxicity in the form of DNA damage for Cu2O and enhanced biocompatibility for CuFeO2 NPs. Genotoxicity estimated by the frequency of sister chromatid exchanges, cytostaticity based on the proliferating rate indices and cytotoxicity based on the mitotic indices at human peripheral lymphocyte cultures were all significantly lower in the case of CuFeO2 NPs. Furthermore, through in vitro albumin denaturation assay, CuFeO2 NPs showed better performance in protein denaturation protection, correlating in superior anti-inflammatory activity than Cu2O and similar to acetylsalicylic acid. Synergy of copper(I)-iron(III) in nanoscale is apparent and gives rise to fruitful bioapplications and perspectives.
