Abstract
Acyl-homoserine lactones (AHLs), mediating pivotal physiological activities through quorum sensing (QS), have conventionally been considered limited to Gram-negative bacteria. However, few reports on the existence of AHLs in Gram-positive bacteria have questioned this conception. Streptomyces, as Gram-positive bacteria already utilizing a lactone-based QS molecule (i.e., gamma-butyrolactones), are yet to be explored for producing AHLs, considering their metabolic capacity and physiological distinction. In this regard, our study examined the potential production of AHLs within Streptomyces by deploying HPLC-MS/MS methods, which resulted in the discovery of multiple AHL productions by S. griseus, S. lavendulae FRI-5, S. clavuligerus, S. nodosus, S. lividans, and S. coelicolor A3(2). Each of these Streptomyces species possesses a combination of AHLs of different size ranges, possibly due to their distinct properties and regulatory roles. In light of additional lactone molecules, we further confirm that AHL- and GBL-synthases (i.e., LuxI and AfsA enzyme families, respectively) and their receptors (i.e., LuxR and ArpA) are evolutionarily distinct. To this end, we searched for the components of the AHL signaling circuit, i.e., AHL synthases and receptors, in the Streptomyces genus, and we have identified multiple potential LuxI and LuxR homologs in all 2,336 Streptomyces species included in this study. The 6 Streptomyces of interest in this study also had at least 4 LuxI homologs and 97 LuxR homologs. In conclusion, AHLs and associated gene regulatory systems could be more widespread within the prokaryotic realm than previously believed, potentially contributing to the control of secondary metabolites (e.g., antibiotics) and their complex life cycle, which leads to substantial industrial and clinical applications.

Abstract
Dedifferentiation of vascular smooth muscle cells (VSMCs) from a functional phenotype to an inverse synthetic phenotype is a symptom of cardiovascular disorders, such as atherosclerosis and hypertension. The sympathetic nervous system (SNS) is an essential regulator of the differentiation of vascular smooth muscle cells (VSMCs). In addition, numerous studies suggest that SNS also stimulates VSMCs to retain their contractile phenotype. However, the molecular mechanisms for this stimulation have not been thoroughly studied. In this study, we used a novel in vitro co-culture method to evaluate the effective cellular interactions and stimulatory effects of sympathetic neurons on the differentiation of VSMCs. We co-cultured rat neural-like pheochromocytoma cells (PC12) and rat aortic VSMCs with this method. Expression of VSMCs contractile genes, including smooth muscle actin (acta2), myosin heavy chain (myh11), elastin (eln), and smoothelin (smtn), were determined by quantitative real-time-PCR analysis as an indicator of VSMCs differentiation. Fold changes for specific contractile genes in VSMCs grown in vitro for seven days in the presence (innervated) and absence (non-innervated) of sympathetic neurons were 3.5 for acta2, 6.5 for myh11, 4.19 for eln, and 4 for smtn (normalized to Tata Binding Protein (TBP)). As a result, these data suggest that sympathetic innervation promotes VSMCs' contractile gene expression and also maintains VSMCs' functional phenotype.

Abstract
BACKGROUND Nitric oxide is a chemical agent produced by endothelial cells in a healthy blood vessel, inhibiting the overgrowth of vascular smooth muscle cells and regulating vessel tone. Liposomes are biocompatible and biodegradable drug carriers with a similar structure to cell bilayer phospholipid membrane, that can be used as useful nitric oxide carriers in vascular grafts. METHOD Using a custom-designed apparatus, the sheep carotid arteries were decellularized while still maintaining important components of the vascular extracellular matrix (ECM), allowing them to be used as small-diameter vascular grafts. A Chemical signal of sodium nitrite was applied to control smooth muscle cells' behavior under static and dynamic cell culture conditions. The thin-film hydration approach was used to create nano-liposomes, which were then used as sodium nitrite carriers to control the drug release rate and enhance the amount of drug-loaded into the liposomes. RESULTS The ratio of 80:20:2 for DPPC: Cholesterol: PEG was determined as the optimum formulation of the liposome structure with high drug encapsulation efficiency (98%) and optimum drug release rate (the drug release rate was 40%, 65%, and 83% after 24, 48 and 72 hours, respectively). MTT assay results showed an improvement in endothelial cells proliferation in the presence of Nano-liposomal Sodium Nitrite (LNS) at the concentration of 0.5μg/ml. Using a suitable concentration of liposomal sodium nitrite (0.5 μg/ml) put onto the constructed scaffold resulted in the controllable development of smooth muscle cells in the experiment. The culture of smooth muscle cells in a pulsatile perfusion bioreactor indicated that in the presence of synthesized liposomal sodium nitrite, the overgrowth of smooth muscle cells was inhibited in dynamic cell culture conditions. The mechanical properties of ECM graft were measured, and a multi-scale model with an accuracy of 83% was proposed to predict mechanical properties successfully. CONCLUSION The liposomal drug-loaded small-diameter vascular graft can prevent the overgrowth of SMCs and the formation of intimal hyperplasia in the graft. Aside from that, the effect of LNS on endothelial has the potential to stimulate endothelial cell proliferation and re-endothelialization.

Abstract
BACKGROUND In vivo drug screening in animal models is contrary to ethical values, costly and time-consuming. Traditional static in vitro models do not reflect the basic characteristics of bone tumor microenvironments; therefore, perfusion bioreactors, in particular, would be an applicable choice due to their advantages to regenerate versatile bone tumor models for studying in vitro novel drug delivery systems. METHODS In this study, an optimal drug formulation of liposomal doxorubicin was prepared, and the release kinetics of the drug and its toxicity effect on MG-63 bone cancer cell line were investigated in two-dimensional, static three-dimensional media on a PLGA/β-TCP scaffold and also in a dynamic media in a perfusion bioreactor. In this assay, the efficacy of the IC50 of this formulation which had been obtained in two-dimensional cell culture (= 0.1 μg/ml), was studied in static and dynamic threedimensional media after 3 and 7 days. Liposomes with good morphology and encapsulation efficiency of 95% had release kinetics of the Korsmeyer-Peppas model. RESULTS The results of cell growth before treatment and cell viability after treatment in all three environments were compared. Cell growth in 2D was rapid, while it was slow in static 3D conditions. In the dynamic 3D environment, it was significant compared to the static tumor models. Cell viability after 3 and 7 days from treatment was 54.73% and 13.39% in 2D conditions, 72.27% and 26.78% in the static 3D model, while 100% and 78.92% in the dynamic culture indicating the effect of drug toxicity over time, but drug resistance of 3D models compared to 2D culture. In the bioreactor, the formulation used in the mentioned concentration showed very small cytotoxicity demonstrating the dominance of mechanical stimuli on cell growth over drug toxicity. CONCLUSION Increasing drug resistance in 3D models compared to 2D models indicates the superiority of liposomal Dox over free form to reduce IC50 concentration.

Abstract
OBJECTIVE In this study, we aimed to develop new Lipo-niosomes based nanoparticles loaded with Amphotericin B (AmB) and Thymus Essential Oil (TEO) and test their effectiveness in the treatment of fungal-infected human adipose stem cells (hASCs). MATERIALS AND METHODS In this experimental study, optimal formulation of AmB and TEO loaded lipo-niosome (based on lipid-surfactant thin-film hydration method) was chemically, and biologically characterized. Therefore, encapsulation capacity, drug release, size, and the survival rate of cells with different concentrations of free and encapsulated AmB/ TEO were evaluated using the MTT method, and its antifungal activity was compared with conventional AmB. RESULTS Lipo-Niosome containing Tween 60 surfactant: cholesterol: Dipalmitoyl phosphatidylcholine (DPPC): Polyethylene glycol (PEG) with a ratio of 20:40:60:3 were chosen as optimal formulation. Lipo-Niosomes entrapment efficiency was 94.15%. The drug release rate after 24 hours was 52%, 54%, and 48% for Lipo-AmB, Lipo-TEO, and Lipo-AmB/TEO, respectively. Physical and chemical characteristics of the Lipo-Niosomes particles indicated size of 200 nm and a dispersion index of 0.32 with a Zeta potential of -24.56 mv. Furthermore, no chemical interaction between drugs and nano-carriers was observed. The cell viability of adipose mesenchymal stem cells exposed to 50 μg/ml of free AmB, free TEO, and free AmB/TEO was 13.4, 58, and 36.9%, respectively. Whereas the toxicity of the encapsulated formulas of these drugs was 48.9, 70.8, and 58.3% respectively. The toxicity of nanoparticles was very low (8.5%) at this concentration. Fluorescence microscopic images showed that the antifungal activity of Lipo-AmB/ TEO was significantly higher than free formulas of AmB, TEO, and AmB/TEO. CONCLUSION In this study, we investigated the efficacy of the TEO/AmB combination, in both free and encapsulatedniosomal form, on the growth of fungal infected-hASCs. The results showed that the AmB/TEO-loaded Lipo-Niosomes can be suggested as a new efficient anti-fungal nano-system for patients treated with hASCs.

Abstract
Synergistic promotion of angiogenesis and osteogenesis in bone tissue-engineered constructs remains a crucial clinical challenge, which might be overcome by simultaneous employment of superior techniques including coculture systems, differentiation-stimulated factors, combinatorial scaffolds and bioreactors.Current study investigated the effect of flow perfusion along with coculture of human adipose stem cells (hASCs) and human umbilical vein endothelial cells (HUVECs) on osteogenic and angiogenic differentiation.Pre-treated hASCs with 1,25-dihydroxyvitamin D3 were seeded onto poly(lactic-co-glycolic acid)/β-tricalcium phosphate/polycaprolactone (PLGA/β-TCP/PCL) scaffold with/without HUVECs, and cultured for 14 days within a flask or modified perfusion bioreactor. Analysis of osteogenic and angiogenic gene expression, alkaline phosphatase (ALP) activity and ALP staining indicates a synergistic effect of perfusion flow and coculture system on osteogenic and angiogenic differentiation. The advantage of modified perfusion bioreactor is its five-branch flow distributor which directly connect to the porous PCL hollow fibers embedded in the 3D scaffold to improve flow and flow-induced shear stress uniformity.Dynamic coculture increased VEGF165 by 6-fold, VEGF189 by 2-fold, and Endothelin-1 by 4-fold, relative to dynamic monoculture. Static coculture enhanced osteogenic and angiogenic differentiation, compared with static monoculture. Although dynamic coculture is in preference to static coculture due to significant increase in ALP activity and promoted angiogenic marker expression. Our finding is the first to indicate that the modified perfusion bioreactor combined with the beneficial cell-cell crosstalk in pre-treated hASC/HUVEC cocultures provides a synergy between osteogenic and angiogenic differentiation of the accumulation of cells, suggesting that it represents a promising approach for regeneration of critical-sized bone defects.

Abstract
The development of decellularized small-diameter vascular grafts is a potential solution for patients requiring vascular reconstructive procedures. However, there is a limitation for acellular scaffolds due to incomplete recellularization and exposure of extracellular matrix components to whole blood resulting in platelet adhesion. To address this issue, a perfusion decellularization method was developed using a custom-designed set up which completely removed cell nuclei and preserved three-dimensional structure and mechanical properties of native tissue (sheep carotid arteries). Afterwards, carboxymethyl kappa carrageenan (CKC) was introduced as a novel anticoagulant in vascular tissue engineering which can inhibit thrombosis formation. The method enabled uniform immobilization of CKC on decellularized arteries as a result of interaction between amine functional groups of decellularized arteries and carboxyl groups of CKC. The CKC modified graft significantly reduced platelet adhesion from 44.53 ± 2.05% (control) to 19.57 ± 1.37% (modified) and supported endothelial cells viability, proliferation, and nitric oxide production. Overall, the novel CKC modified scaffold provides a promising solution for thrombosis formation of small-diameter vessels and could be a potent graft for future in vivo applications in vascular bypass procedures. © 2019 Wiley Periodicals, Inc.

Abstract
In this paper, an optical-electrochemical nano-biosensor was introduced for measuring Cu2+ ion concentrations in water. A multi-step procedure was used to fabricate the transparent-conductive biosensor platform consisting of an l-cysteine–gold nanoparticle-based sandwich structure. First, colloidal gold nanoparticles (GNPs) were synthesized according to the Turkevich–Frens method with some modifications and then functionalized with l-cysteine molecules (GNP/l-cys). Then, cyclic voltammetry was preformed in buffered solutions containing HAuCl4·3H2O for gold nanoparticle electrodeposition on cleaned ITO glasses. The GNP-electrodeposited ITO glasses (ITO/GNPs) were thermally treated in air atmosphere for 1 hour at a temperature of 300 °C. Following the procedure, the gold nanoparticles on ITO/GNPs substrates were functionalized with l-cysteine to prepare ITO/GNPs/l-cys substrates. Finally, the sandwich-type substrates of ITO/GNPs/l-cys⋯Cu2+⋯l-cys/GNPs were fabricated by accumulation of Cu2+ ions using an open circuit technique performed in copper ion buffer solutions in the presence of previously produced colloidal GNP/l-cys nanoparticles. The effective parameters including GNP/l-cys solution volume, pre-concentration pH and pre-concentration time on the LSPR and SWV responses were investigated and optimized. The fabricated transparent-conductive platforms were successfully assessed as a nano-biosensor for detection of copper ions using two different methods of square wave voltammetry (SWV) and localized surface plasmon resonance (LSPR). As a result, the proposed biosensor showed a high sensitivity, selectivity and a wide detectable concentration range to copper ions. The total linear range and the limit of detection (LOD) of the nano-biosensor were 10–100 000 nM (0.6–6354.6 ppb) and below 5 nM (0.3 ppb), respectively. The results demonstrated the potential of combining two different optical and electrochemical methods for quantitation of the single analyte on the same biosensor platform and obtaining richer data. Also, these results indicated that the developed LSPR-SWV biosensor was superior to many other copper biosensors presented in the literature in terms of linear range and LOD. The developed nano-biosensor was successfully applied in the determination of trace Cu2+ concentration in actual tap water samples. The transparent-conductive platforms of ITO/GNPs/l-cys⋯Cu2+⋯l-cys/GNPs were fabricated for quantitation of Cu2+ ions in water samples using combined LSPR and SWV methods.![]()

Abstract
Purpose Osteosarcoma (OS) mostly affects children and young adults, and has only a 20%–30% 5-year survival rate when metastasized. We aimed to create dual-targeted (extracellular against EphA2 and intracellular against JNK-interacting protein 1 [JIP1]), doxorubicin (DOX)-loaded liposomes to treat OS metastatic disease. Materials and methods Cationic liposomes contained N-[1-(2,3-dioleoyloxy)propyl]-N,N,N-trimethylammonium methyl-sulfate (DOTAP), cholesterol, 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC), and distearoyl-phosphatidylethanolamine–methyl-poly(ethylene glycol) (DSPE–mPEG) conjugate. EphA2 targeting was accomplished by conjugating YSA peptide to DSPE–mPEG. Vesicles were subsequently loaded with DOX and JIP1 siRNA. Results Characteristics assessment showed that 1) size of the bilayered particles was 109 nm; 2) DOX loading efficiency was 87%; 3) siRNA could be successfully loaded at a liposome:siRNA ratio of >24:1; and 4) the zeta potential was 18.47 mV. Tumor-mimicking pH conditions exhibited 80% siRNA and 50.7% DOX sustained release from the particles. Stability studies ensured the protection of siRNA against degradation in serum. OS cell lines showed increased and more pericellular/nuclear localizations when using targeted vesicles. Nontargeted and targeted codelivery caused 70.5% and 78.6% cytotoxicity in OS cells, respectively (free DOX: 50%). Targeted codelivery resulted in 42% reduction in the siRNA target, JIP1 mRNA, and 46% decrease in JIP1 levels. Conclusion Our dual-targeted, DOX-loaded liposomes enhance toxicity toward OS cells and may be effective for the treatment of metastatic OS.

Abstract
Cationic liposomes have been investigated as non-viral vectors for gene delivery for more than a decade to overcome challenges associated with viral gene delivery. However, due to instability of liposomes, siRNA delivery is still a serious problem. In this study, we developed stealth PEGylated liposome formulations and focused on the effects of PEGylated liposomes on parameters related to size, zeta potential, polydispersity index, siRNA-loading efficiency and long-term stability of the siRNA-liposome complex. We were able to generate siRNA lipoplexes that could be very efficiently loaded, did not aggregate, could be stored at 4 °C for at least 6 months with only marginal release (1-5%) of siRNA and enhanced intracellular delivery of siRNA. Moreover, we could demonstrate that PEGylation positively contributed to all these parameters compared to liposomes, which were not PEGylated. The prepared lipoplex was successfully silenced J1P1 expression in MG-63 osteosarcoma cell line. In conclusion, our novel PEGylated liposomes have high potential for systemic delivery of siRNA and can improve in vivo stability of free siRNA and also siRNA lipoplexes.

Abstract
OBJECTIVE In this study we prepared a novel formulation of liposomal doxorubicin (L- DOX). The drug dose was optimized by analyses of cellular uptake and cell viability of osteosarcoma (OS) cell lines upon exposure to nanoliposomes that contained varying DOX concentrations. We intended to reduce the cytotoxicity of DOX and improve characteristics of the nanosystems. MATERIALS AND METHODS In this experimental study, we prepared liposomes by the pH gradient hydration method. Various characterization tests that included dynamic light scattering (DLS), cryogenic transmission electron microscopy (Cryo-TEM) imaging, and UV- Vis spectrophotometry were employed to evaluate the quality of the nanocarriers. In addition, the CyQUANT® assay and fluorescence microscope imaging were used on various OS cell lines (MG-63, U2-OS, SaOS-2, SaOS-LM7) and Human primary osteoblasts cells, as novel methods to determine cell viability and in vitro transfection efficacy. RESULTS We observed an entrapment efficiency of 84% for DOX within the optimized liposomal formulation (L-DOX) that had a liposomal diameter of 96 nm. Less than 37% of DOX released after 48 hours and L-DOX could be stored stably for 14 days. L-DOX increased DOX toxicity by 1.8-4.6 times for the OS cell lines and only 1.3 times for Human primary osteoblasts cells compared to free DOX, which confirmed a higher sensitivity of the OS cell lines versus Human primary osteoblasts cells for L-DOX. We deduced that L- DOX passed more freely through the cell membrane compared to free DOX. CONCLUSION We successfully synthesized a stealth L-DOX that contained natural phospholipid by the pH gradient method, which could encapsulate DOX with 84% efficiency. The resulting nanoparticles were round, with a suitable particle size, and stable for 14 days. These nanoparticles allowed for adequately controlled DOX release, increased cell permeability compared to free DOX, and increased tumor cell death. L-DOX provided a novel, more effective therapy for OS treatment.

Abstract
A novel approach was developed for the preparation of stealth controlled-release liposomal doxorubicin. Various liposomal formulations were prepared by employing both thin film and pH gradient hydration techniques. The optimum formulation contained phospholipid and cholesterol in 1:0.43 molar ratios in the presence of 3% DSPE-mPEG (2000). The liposomal formulation was evaluated by determining mean size of vesicle, encapsulation efficiency, polydispersity index, zeta potentials, carrier's functionalization, and surface morphology. The vesicle size, encapsulation efficiency, polydispersity index, and zeta potentials of purposed formula were 93.61 nm, 82.8%, 0.14, and -23, respectively. Vesicles were round-shaped and smooth-surfaced entities with sharp boundaries. In addition, two colorimetric methods for cytotoxicity assay were compared and the IC50 (the half maximal inhibitory concentration) of both methods for encapsulated doxorubicin was determined to be 0.1 μg/ml. The results of kinetic drug release were investigated at several different temperatures and pH levels, which showed that purposed formulation was thermo and pH sensitive.

Abstract
This study focuses on the development of a universal mathematical model for drug release kinetics from liposomes to allow in silico prediction of optimal conditions for fine-tuned controlled drug release. As a prelude for combined siRNA-drug delivery, nanoliposome formulations were optimized using various mole percentages of a cationic lipid (1,2-dioleoyl-3-trimethylammonium-propane, DOTAP) in the presence or absence of 3 mol% distearoyl phosphoethanolamine, polyethylene glycol (PEG-2000mDSPE). Outcome parameters were particle size, zeta potential, entrapment efficiency, in vitro drug release, and tumor cell kill efficiency. The optimized formula (containing 20% DOTAP with 3% DSPE-mPEG(2000) was found to be stable for six months, with round-shaped particles without aggregate formation, an average diameter of 71 nm, a suitable positive charge, and 89% drug encapsulation efficiency (EE). The 41% drug release during 6 h confirmed controlled release. Furthermore, the release profiles as functions of pH and temperature were investigated and the kinetics of the drug release could adequately be fitted to Korsmeyer-Peppas' model by multiple regression analysis. The statistical parameters confirmed good conformity of final models. Functionality of the novel cationic liposome formulations (± DOX) was tested on osteosarcoma (OS) cell lines. Increased OS cell toxicity (1.3-fold) was observed by the DOX-loaded vs. the free DOX. A feasibility pilot showed that siRNA could be loaded efficiently as well. In conclusion, we have established a predictive mathematical model for the fine-tuning of controlled drug release from liposomal formulations, while creating functional drug-delivery liposomes with potential for siRNA co-delivery to increase specificity and efficacy.

Abstract
OBJECTIVE This study aimed to evaluate a co-encapsulated pegylated nano-liposome system based on two herbal anti-tumor drugs, silibinin and glycyrrhizic acid, for delivery to a hepatocellular carcinoma (HCC) cell line (HepG2). MATERIALS AND METHODS In this experimental study, co-encapsulated nano-liposomes by the thin layer film hydration method with HEPES buffer and sonication at 60% amplitude. Liposomes that co-encapsulated silibinin and glycyrrhizic acid were prepared with a specified molar ratio of dipalmitoylphosphatidylcholine (DPPC), cholesterol (CHOL), and methoxy-polyethylene glycol 2000 (PEG2000)-derived distearoyl phosphatidylethanolamine (mPEG2000-DSPE). We used the MTT technique to assess cytotoxicity for various concentrations of co-encapsulated nano-liposomes, free silibinin (25% w/v) and glycyrrhizic acid (75% w/v) on HepG2 and fibroblast cell lines over a 48-hour period. RESULTS Formulation of pegylated nano-liposomes showed a narrow size distribution with an average diameter of 46.3 nm. The encapsulation efficiency (EE) for silibinin was 24.37%, whereas for glycyrrhizic acid it was 68.78%. Results of in vitro cytotoxicity showed significantly greater co-encapsulated nano-liposomes on the HepG2 cell line compared to the fibroblast cell line. The half maximal inhibitory concentration (IC50) for co-encapsulated pegylated nanoliposomal herbal drugs was 48.68 µg/ml and free silibinin with glycyrrhizic acid was 485.45 µg/ml on the HepG2 cell line. CONCLUSION This in vitro study showed that nano-liposome encapsulation of silibinin with glycyrrhizic acid increased the biological activity of free drugs, increased the stability of silibinin, and synergized the therapeutic effect of silibinin with glycyrrhizic acid. The IC50 of the co-encapsulated nano-liposomes was lower than the combination of free silibinin and glycyrrhizic acid on the HepG2 cell line.

Abstract
In this paper we present the preliminary results of a novel biological analysis platform for early colon cancer detection using magnetic separation of magnetized markers. The platform consists of a microfluidic structure integrated with biosensors. Super-Paramagnetic Iron Oxide nanoparticles (SPIO-NPs) were functionalized with purified DNA Aptamer and their synthesis is described. In this paper, we also present the physicochemical results of the synthesized SPIO/Au-NPs characterized by TEM and XRD. Toxicity of our synthesized biomarkers on HCT116 cell line is discussed. Based on our findings, a concentration of 1mg/ml of our biomarkers added to 5 × 105 cells per well has no effect the viability of the human cells even after 24 hours.

Abstract
Blood oxygenation is the main performance characteristic of capillary membrane oxygenators (CMOs). Handling of natural blood in in vitro investigations of CMOs is quite complex and time-consuming. Since the conventional blood analog fluids (e.g. water/glycerol) lack a substance with an affinity to capture oxygen comparable to hemoglobin's affinity, in this study a novel approach using modified sulfite solution is proposed to address this challenge. The solution comprises sodium sulfite as a component, simulating the role of hemoglobin in blood oxygenation. This approach is validated by OTR (oxygen transfer rate) measured using native porcine blood, in two types of commercially available CMOs. Consequently, the number of complicated natural blood investigations in the evolution procedure of newly developed oxygenators would considerably decrease. Moreover, the reassessing of failed devices, in clinics, would be performed more precisely using a modified sulfite solution than simple water/glycerol testing.

Abstract
Neural tissue engineering is one of the most promising strategies for treatment of nerve tissue injuries. Three-dimensional (3D) environment mimics in vivo conditions for cells. 3D distribution and growth of the cells within the scaffold are both important for neural tissue engineering. In this study, endometrial stromal cell-derived oligodendrocyte progenitor cells (EnSC-derived OPCs) were cultured in fibrin gel and cell differentiation and viability were evaluated after 8 days of post-culture. The structural and mechanical characteristics of fibrin gel-like scaffold were examined with rheological analysis. EnSCs were isolated from donor tissue and were induced to OPCs with growth factors (FGF2/EGF/PDGF-AA) for 12 days, then were cultured in fibrin gel with Triiodothyronine (T3) medium for another 8 days. The viability of cells was analyzed using MTT assay for a period of 8 days culturing in a fibrin matrix. Structure of fibrin matrix and cell morphology was analyzed with SEM. TEM, immunostaining and quantitative RT-PCR was performed for OPCs markers after cell culturing in fibrin matrix. Cell viability is enhanced in fibrin matrix after 8 days. SEM and TEM show that cells are in good integration with nano-fibers. Moreover, immunohistochemistry and quantitative RT-PCR of OPCs differentiation markers showed that Olig2, Sox10, PDGFRa, CNP, and A2B5 are expressed after 8 days culturing within fibrin matrix. Fibrin can provide a suitable 3-D scaffold for EnSCs differentiated cells for the regeneration of CNS.
