Nanocomposite scaffolds for accelerating chronic wound healing by enhancing angiogenesis.

Skin 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.

The potential renal toxicity of silver nanoparticles after repeated oral exposure and its underlying mechanisms.

BACKGROUND: Silver nanoparticles (AgNPs) can accumulate in various organs after oral exposure. The main objective of the current study is to evaluate the renal toxicity induced by AgNPs after repeated oral exposure and to determine the relevant molecular mechanisms. METHODS: In this study, 40 male Wistar rats were treated with solutions containing 30, 125, 300, and 700 mg/kg of AgNPs. After 28 days of exposure, histopathological changes were assessed using hematoxylin-eosin (H&E), Masson's trichrome, and periodic acid-Schiff (PAS) staining. Apoptosis was quantified by TUNEL and immunohistochemistry of caspase-3, and the level of expression of the mRNAs of growth factors was determined using RT-PCR. RESULTS: Histopathologic examination revealed degenerative changes in the glomeruli, loss of tubular architecture, loss of brush border, and interrupted tubular basal laminae. These changes were more noticeable in groups treated with 30 and 125 mg/kg. The collagen intensity increased in the group treated with 30 mg/kg in both the cortex and the medulla. Apoptosis was much more evident in middle-dose groups (i.e., 125 and 300 mg/kg). The results of RT-PCR indicated that Bcl-2 and Bax mRNAs upregulated in the treated groups (p < 0.05). Moreover, the data related to EGF, TNF-α, and TGF-ß1 revealed that AgNPs induced significant changes in gene expression in the groups treated with 30 and 700 mg/kg compared to the control group. CONCLUSION: Our observations showed that AgNPs played a critical role in in vivo renal toxicity.

Evaluation radioprotective effect of curcumin conjugated albumin nanoparticles.

In this research, curcumin (CUR) conjugated albumin based nanoparticles (BSA-CUR) were designed for improvement and evaluation radioprotective effect of CUR. In this way, we have prepared BSA-CUR by covalently binding the CUR with BSA. Next, this synthesized prodrug was evaluated for physical and chemical properties by Fourier-transform infrared (FTIR), Dynamic light scattering (DLS), Transmission electron microscopy (TEM), Ultraviolet-visible (UV/Vis), and Differential scanning calorimetry (DSC) analysis. Furthermore, the chemical stability of designed prodrug was appraised. The result shows that the size of nanoparticles is 174.4 nm with a polydispersity index (PdI) of 0.191. The nanoparticles have a high loading capacity and show sustained release behavior. Loading of CUR to BSA not only could increase the chemical stability of CUR, but also could improve radioprotection efficacy of it's against X-Ray irradiation. The HHF-2 cells show 107% viability in the presence of BSA-CUR at a concentration of 50 µg/mL, whereas non-treated cells show 46% viability, under X-Ray irradiation. Also in vivo study results show that, four out of five mice have died when the mice irradiated by X-Ray and no received any treatment. Although, for a group that treated with BSA-CUR and also irradiated by X-Ray, median survival and survival rate was higher than CUR treated and control mice, and only two out of five mice have died. The result of this study proved that BSA-CUR can be used as a proficient vehicle for improving the potential radioprotective effect of CUR.

Biopolymer-based scaffolds for corneal stromal regeneration: A review.

The stroma is one of the 5 layers of the cornea that comprises more than 90% of the corneal thickness, and is the most important layer for the transparency of cornea and refractive function critical for vision. Any significant damage to this layer may lead to corneal blindness. Corneal blindness refers to loss of vision or blindness caused by corneal diseases or damage, which is the 4th most common cause of blindness worldwide. Different approaches are used to treat these patients. Severe corneal damage is traditionally treated by transplantation of a donor cornea or implantation of an artificial cornea. Other alternative approaches, such as cell/stem cell therapy, drug/gene delivery and tissue engineering, are currently promising in the regeneration of damaged cornea. The aim of tissue engineering is to functionally repair and regenerate damaged cornea using scaffolds with or without cells and growth factors. Among the different types of scaffolds, polymer-based scaffolds have shown great potential for corneal stromal regeneration. In this paper, the most recent findings of corneal stromal tissue engineering are reviewed.

Preparation and characterization of poly(ethylene oxide)/zinc oxide nanofibrous scaffold for chronic wound healing applications.

BACKGROUND: Skin, the first barrier to pathogens, loses its integrity and function after an injury. The presence of an antibacterial dressing at the wound site may prevent bacterial invasion and also improve the healing process. OBJECTIVES: The current study aimed to fabricate a biomimetic membrane with antibacterial properties for healing chronic wounds. MATERIAL AND METHODS: The membranes, fabricated through electrospinning, are comprised of poly(ethylene oxide) (PEO) and zinc oxide nanoparticles (ZnO-NPs) as the main biomaterial and antibacterial agent, respectively. Antibacterial activity, cell attachment and viability were tested to evaluate the biological properties of the membranes. The optimal cell compatible concentration of ZnO-NPs was determined for further studies. In vitro characterization of the membranes was performed to confirm their suitable properties for wound healing. RESULTS: The antibacterial PEO/ZnO-NP membrane containing 2% of nanoparticles showed no cell toxicity, and human fibroblast cells were able to adhere and proliferate on the scaffold. The in vitro results from the tensile test, wettability, porosity, and protein adsorption revealed appropriate properties of the membrane as a scaffold for skin tissue engineering. CONCLUSIONS: Synthetic polymers have been widely used for tissue engineering applications. The proper characteristics of PEO nanofibers, including a high ratio of surface/volume, moderate hydrophilicity and good mechanical properties, make this polymer interesting for skin regeneration. The results demonstrate the potential of the antibacterial PEO/ZnO-NP membrane to be used as an engineered scaffold to improve the wound healing process.

In this project methotrexate (MTX) conjugated albumin based nanoparticles (MTX-BSA) loaded with curcumin (CUR) drug (CUR-MTX-BSA) for simultaneous delivery of multi-chemotherapeutic drugs and combination cancer therapy were designed. Co-delivery is a new strategy which minimize the amount of each drug, reduce of side effects and also to achieve the synergistic effect for cancer therapies. The MTX was conjugated to albumin via covalent bond. Next, this synthesized prodrug loaded with CUR. Afterward, the formulations were evaluated for physical and chemical properties by DLS, TEM, FTIR, UV/Vis, DSC analysis, in vitro cytotoxicity and in vivo biocompatibility studies. Furthermore, the drug loading and release study were evaluated. Proteinase K enzyme was used to break amid bond between MTX and BSA and also amidic bonds in BSA structure. Administration of up to 2000 mg/kg of BSA to healthy animals was non-toxic and all treated mice were still alive after 24 h. The result of this study proved that CUR-MTX-BSA can be used as a proficient vehicle for effective co-delivery of CUR and MTX in the treatment of cancer.

In this study, we designed a polymersome system for the controlled release of methotrexate (MTX) as an anticancer drug with the objective of improving the loading efficiency of the drug in polymersomes as well as achievement of an efficient control on the release rate of drug from nanocarriers. We synthesized mono methoxy poly(ethylene glycol)-poly(e-caprolactone) (mPEG-PCL) diblock copolymers. The structure of the copolymers was characterized by proton nuclear magnetic resonance spectroscopy (1H NMR), Fourier transform infrared spectroscopy (FT-IR), and differential scanning calorimetry (DSC) techniques. MTX was encapsulated within nanoparticles (NPs) through multiple emulsion method. The resulting NPs were characterized further by various techniques such as atomic force microscopy (AFM) and dynamic light scattering (DLS). Next, the various kinetic equations were fitted to the release data of MTX from MTX-loaded mPEG-PCL polymersomes. The results showed that the zeta potential of MTX-loaded mPEG-PCL polymersomes was about -5.49 mV and the average size was 49.18 nm. MTX was encapsulated into polymersomes loading capacity of 12 ± 0.09% and encapsulation efficiency of 45.5 ± 0.41%. The metabolic activity assays of void of MTX, mPEG-PCL polymersomes, and MTX-loaded mPEG-PCL polymersomes were compared to each other by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay of the treated MCF-7 cell lines. It can be concluded that application of NPs is a better and more effective strategy for controlled and slow release of MTX in the treatment of cancer.

Directed Differentiation of Adipose-Derived Stem Cells Using Imprinted Cell-Like Topographies as a Growth Factor-Free Approach.

The influence of surface topography on stem cell behavior and differentiation has garnered significant attention in regenerative medicine and tissue engineering. The cell-imprinting method has been introduced as a promising approach to mimic the geometry and topography of cells. The cell-imprinted substrates are designed to replicate the topographies and dimensions of target cells, enabling tailored interactions that promote the differentiation of stem cells towards desired specialized cell types. In fact, by replicating the size and shape of cells, biomimetic substrates provide physical cues that profoundly impact stem cell differentiation. These cues play a pivotal role in directing cell morphology, cytoskeletal organization, and gene expression, ultimately influencing lineage commitment. The biomimetic substrates' ability to emulate the native cellular microenvironment supports the creation of platforms capable of steering stem cell fate with high precision. This review discusses the role of mechanical factors that impact stem cell fate. It also provides an overview of the design and fabrication principles of cell-imprinted substrates. Furthermore, the paper delves into the use of cell-imprinted polydimethylsiloxane (PDMS) substrates to direct adipose-derived stem cells (ADSCs) differentiation into a variety of specialized cells for tissue engineering and regenerative medicine applications. Additionally, the review discusses the limitations of cell-imprinted PDMS substrates and highlights the efforts made to overcome these limitations.

Cerium oxide nanoparticles: Synthesis methods and applications in wound healing.

Wound care and treatment can be critical from a clinical standpoint. While different strategies for the management and treatment of skin wounds have been developed, the limitations inherent in the current approaches necessitate the development of more effective alternative strategies. Advances in tissue engineering have resulted in the development of novel promising approaches for accelerating wound healing. The use of various biomaterials capable of accelerating the regeneration of damaged tissue is critical in tissue engineering. In this regard, cerium oxide nanoparticles (CeO2 NPs) have recently received much attention because of their excellent biological properties, such as antibacterial, anti-inflammatory, antioxidant, and angiogenic features. The incorporation of CeO2 NPs into various polymer-based scaffolds developed for wound healing applications has led to accelerated wound healing due to the presence of CeO2 NPs. This paper discusses the structure and functions of the skin, the wound healing process, different methods for the synthesis of CeO2 NPs, the biological properties of CeO2 NPs, the role of CeO2 NPs in wound healing, the use of scaffolds containing CeO2 NPs for wound healing applications, and the potential toxicity of CeO2 NPs.

Enhanced In Vivo Radiotherapy of Breast Cancer Using Gadolinium Oxide and Gold Hybrid Nanoparticles.

Radiation therapy has demonstrated promising effectiveness against several types of cancers. X-ray radiation therapy can be made further effective by utilizing nanoparticles of high-atomic-number (high-Z) materials that act as radiosensitizers. Here, in purpose of maximizing the radiation therapy within tumors, bovine serum albumin capped gadolinium oxide and gold nanoparticles (Gd2O3@BSA-Au NPs) are developed as a bimetallic radiosensitizer. In this study, we incorporate two high-Z-based nanoparticles, Au and Gd, in a single nanoplatform. The radiosensitizing ability of the nanoparticles was assessed with a series of in vitro tests, following evaluation in vivo in a breast cancer murine model. Enhanced tumor suppression is observed in the group that received radiation after administration of Gd2O3@BSA-Au NPs. As a result, cancer therapy efficacy is significantly improved by applying Gd2O3@BSA-Au NPs under X-ray irradiation, as evidenced by studies evaluating cell viability, proliferation, reactive oxygen species production, and in vivo anti-tumor effect.

Silver sulfide coated alginate radioenhancer for enhanced X-ray radiation therapy of breast cancer.

A wide range of high-Z nanomaterials are fabricated to decrease radiation dose by sensitizing cells to irradiation through various mechanisms such as ROS generation enhancement. Alginate-coated silver sulfide nanoparticles (Ag2S@Alg) were synthesized and characterized by SEM, TEM, DLS, XRD, EPS, FT-IR, and UV-vis analysis techniques. Cytotoxicity of nanoparticles was tested against HFF-2, MCF-7, and 4 T1 cell lines for biocompatibility and radio enhancement ability evaluation, respectively. Moreover, the hemolysis assay demonstrated that the nanoparticles were biocompatible and nontoxic. In vitro intracellular ROS generation and calcein AM/PI co-staining unveiled cancerous cell death induction by nanoradiosensitizer, Ag2S@Alg. Further, histopathology results emphasized the tumor ablation capability of Ag2S@Alg. Silver anticancer properties were also recognized and combined with its radiosensitizing effect under X-ray irradiation.

Magnetic ferrite nanoparticles coated with bovine serum albumin and glycine polymers for controlled release of curcumin as a model.

To conquer the low water solubility and bioavailability of curcumin (CUR), to corroborate its functional qualities and to broaden its applicability in the pharmaceutical sector, numerous nanoscale methods have been widely exploited for its administration. Because of its polycystic, biodegradable, biocompatibility, non-toxicity, and non-allergenic properties, bovine serum albumin (BSA) and glycine (Gly) have been actively investigated as natural biopolymers for decades. Various BSA and Gly-based nanocarriers with unique features for CUR delivery, such as magnetic ferrite nanoparticles, are being developed (MNPs). In this work, magnesium ferrite (MgFe2O4)/BSA and nickel ferrite (NiFe2O4)/Gly nanocomposites loaded with CUR (drug model) were manufactured for the first time using a chemical co-precipitation approach to create biocompatible drug nanocarriers. It was found that the synthesized MgFe2O4/BSA and NiFe2O4/Gly nanoparticles have a uniform particle distribution and their size is much less than 100 nm. Saturation magnetization in MgFe2O4 and NiFe2O4 reaches 13.07 and 33.4 emu/g the remarkable peak of magnetization decreases to 10.99 and 32.36 emu/g after the addition of polymers. These analyses also showed the presence of chemical bonds in the structure of the nanocomposite. The curcumin diffusion process in NPs were determined using a mathematical modeling. The yielding of the product for MgFe2O4/BSA and NiFe2O4/Gly in 200 h is about 72 and 63%, respectively. Also, regressed relative diffusivities (D/R2), including effective steric hindrance, were determined as 5.75 × 10-4 and 2.72 × 10-4 h-1 for MgFe2O4/BSA and NiFe2O4/Gly, respectively. It shows that there is a significant steric barrier that significantly deviates from the molecular diffusion of the liquid. As a result, the low effective release of curcumin in the particles is more noticeable. Our study demonstrated the effective relationship between the polymer architecture and the biophysical properties of the resulting nanoparticles and shed light on new approaches for the design of efficient NP-based drug carriers.
