Neuroprotective functions of different types of stem cells in the nervous system have been evaluated in many studies investigating the effectiveness of these cells in various retinal disease models. Neural progenitor cells (NPCs) secrete an assortment of trophic factors that are vital to the protection of the visual system. We aimed to assess the therapeutic potentials of NPCs in an ONC mouse model. Materials and Methods In this experimental study, NPCs were produced using noggin and retinoic acid from human embryonic stem cells (hESCs). Fifty mice were divided into the following three groups: i. Intact , ii. Vehicle [optic nerve crush+Hank’s balanced salt solution (HBSS)], and iii. Treatment (optic nerve crush+NPCs). The visual behavior of the mice was examined using the Visual Cliff test, and in terms of RGC numbers, they were assessed by Brn3a immunostaining and retrograde tracing using DiI injection. Results Intravenous injection of 50,000 NPCs through visual cliff did not produce any visual improvement. However, our data suggest that the RGCs protection was more than two-times in NPCs compared to the vehicle group as examined by Brn3a staining and retrograde tracing. Conclusion Our study indicated that intravenous injection of NPCs could protect RGCs probably mediated by trophic factors. Due to this ability and good manufacturing practices (GMP) grade production feasibility, NPCs may be used for optic nerve protection.","PeriodicalId":9692,"journal":{"name":"Cell Journal (Yakhteh)","volume":"67 1","pages":"120 - 126"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80244313","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}

Understanding the signaling pathways in astrocytes can be a great help in treating of AD. This study aimed to investigate signaling pathway relations between low dose of methamphetamine (METH), the apoptosis, cell cycle, and glutamine (Gln) pathways in the activated astrocyte. Materials and Methods In this experimental study, the activated astrocyte cells were exposed to a low dose of METH (12.5 µM) which was determined by Thiazolyl blue tetrazolium bromide (MTT) method. The groups were: group 1 cells with Aβ, group 2 cells with METH, group 3 cells with METH after 24 hours of adding Aβ (Aβ+METH, treated group), group 4 cells with Aβ after 24 hours of adding METH (METH+Aβ, prevention group), and group 5 as the control. The Gln was assayed by high-performance liquid chromatography (HPLC), and also the apoptosis, and cell cycle and BAX, BCL-X expression was evaluated. Results The amount of Gln was increased, and the value of late and early apoptosis was reduced in the treatment groups, and necrosis is decreased in the prevention group (group 4 compared to group 1). Moreover, it was revealed through cell cycle analysis that G2 in group 4 was reduced compared to group 1 and the expression of BAX, BAX/ BCL-X, and BCL-X in group 3 and group 4, was decreased and increased, respectively compared to group 1. Conclusion These findings suggest that perhaps a non-toxic dosage of METH (low dose) can reduce the amount of apoptosis and BAX expression and increase the expression of BCL-X. Furthermore, the cells are arrested in the G2 phase and can raise the amount of extracellular glutamine, which has a protective role in neuron cells. These findings may provide a new perspective to design a new drug with less toxic results.","PeriodicalId":9692,"journal":{"name":"Cell Journal (Yakhteh)","volume":"38 1","pages":"105 - 111"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79850715","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 pathogenesis of cHCC- CC is poorly understood due to a shortage of suitable in vitro models. Due to scarce availability of human liver tissue, induced pluripotent stem cells (iPSCs) are a useful alternative source to produce renewable liver cells. For use in the development of liver pathology models, here we successfully developed and evaluated iPSCs from liver fibroblasts of a patient with cHCC-CC. Materials and Methods In this experimental study, human liver fibroblasts (HLFs) were obtained from the liver biopsy of a 69-year-old male patient with cHCC-CC and transduced with a retroviral cocktail that included four factors - OCT4, SOX2, KLF4, and c-MYC (OSKM). Pluripotency of the iPSCs was determined by alkaline phosphatase (AP) staining, quantitative real-time polymerase chain reaction (PCR), and immunofluorescence. We induced in vitro embryoid body (EB) formation and performed an in vivo teratoma assay to confirm their differentiation capacity into the three germ layers. Results HLF iPSCs derived from the cHCC-CC patient displayed typical iPSC-like morphology and pluripotency marker expression. The proficiency of the iPSCs to differentiate into three germ layers was assessed both in vitro and in vivo. Compared to normal control iPSCs, differentiated HLF iPSCs showed increased expressions of HCC markers alpha-fetoprotein (AFP) and Dickkopf-1 (DKK1) and the CC marker cytokeratin 7 (CK7), and a decreased expression of the CC tumour suppressor SRY-related HMG-box 17 (SOX17). Conclusion We established HLF iPSCs using liver fibroblasts from a patient with cHCC-CC for the first time. The HLF iPSCs maintained marker expression in the patient when differentiated into EBs. Therefore, HLF iPSCs may be a sustainable cell source for modelling cHCC-CC and beneficial for understanding liver cancer pathology and developing therapies for cHCC-CC treatment.","PeriodicalId":9692,"journal":{"name":"Cell Journal (Yakhteh)","volume":"1 1","pages":"133 - 139"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83663770","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}

This study aimed to investigate the role of long intergenic non-protein coding RNA 174 (LINC00174) in NSCLC. Materials and Methods In this experimental study, LINC00174 expression in NSCLC tissues and cell lines was investigated by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Besides, cell counting kit-8 (CCK-8), 5-bromo-2'-deoxyuridine (BrdU). Transwell and Flow Cytometry assays were applied to detect the regulatory function of LINC00174 on the growth, migration and apoptosis of NSCLC cells. Bioinformatics analysis, dual luciferase reporter gene assay and RNA immunoprecipitation (RIP) assay predicted and verified the targeting relationship between LINC00174 and miR-31-5p, and between miR-31-5p and the 3´-untranslated region (3´UTR) of large tumor suppressor kinase 2 (LATS2), respectively. Western blotting was performed to detect the regulatory function of LINC00174 and miR-31-5p on LATS2 protein expression. Results Compared with that in normal lung tissues, LINC00174 expression in NSCLC tissues and cell lines was reduced. LINC00174 expression was negatively associated with the TNM stage of the patients. Functional experiments showed that LINC00174 overexpression inhibited NSCLC cell multiplication and migration, and induced apoptosis. Furthermore, LINC00174 targeted miR-31-5p and repressed its expression. Additionally, LINC00174 upregulated LATS2 expression through competitively binding to miR-31-5p.

Materials and Methods In this experimental study, twelve adult female rats weighting 180-220 g were randomly divided into case and control groups. Hypothyroidism was induced by dissolving 0.1 g/L of 6-n-propyl-2-thiouracil in drinking water toward the end of pregnancy and lactation. At the end of the breastfeeding period, the blood samples of female children were collected. Six healthy, mature, female rats were selected and kept until they reached maturity, and were then mated with male rats. After observing the female rats’ delivery, blood samples were collected from their male and female newborns and the healthy rats were selected. Results There was a significant difference in the volume and size of ovarian as well as in the number of secondary follicles in comparison with the control group (P=0.025). However, there were no significant changes in the other parameters including the number of primary follicles, the number of Graafian follicles and sperm parameters.

Recently therapeutic progress in retinal degeneration, using human embryonic stem cells (hESCs), has been facing technical challenges, demanding the development of simple and standardized protocols. In addition to the designing of the protocols, characterization of the obtained cells is highly required for confirming the reliability of the applied methods for future medical applications. Previously, we showed that human stem cells from apical papilla (SCAP) have stromal cell-derived inducing activity (SDIA). Materials and Methods In this experimental study, we developed an efficient retinal differentiation protocol, based on the co-culture of confluent hESCs and SCAP in the absence of exogenous molecules, such as activators or inhibitors of molecular signaling pathways. This experimental procedure resulted in the generation of self-forming neural retina (NR)-like structures containing retinal progenitor cells (RPCs) within 4 weeks. Results We have focused on the characterization of the derived RPCs, as a crucial step towards further verification of the efficiency of our previously suggested protocol. The differentiated cells expressed eye-field markers, PAX6, RAX, LHX2, and SIX3, and also generated neurospheres by a floating culture system for one week. Conclusion We have reported that the treatment of hESC-derived RPCs by the Notch pathway-inhibitor induced the generation of photoreceptor precursor cells (PPCs). The presented method demonstrates the fact that a co-culture of hESCs and SCAP without exogenous molecules provides an efficient approach to produce RPCs for the treatment of retinal disease, and act as an in vitro model for the development of human retina.","PeriodicalId":9692,"journal":{"name":"Cell Journal (Yakhteh)","volume":"90 1","pages":"127 - 132"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82361911","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}

Therefore, it can be considered as an inducer for cell replacement therapies in diabetes. The main goal of this research is to successfully culture and induce differentiation of human Wharton’s jelly mesenchymal stem cells (hWJMSCs) into Sox17-expressing cells using a Wnt/β-catenin pathway agonist (SKL2001) plus nanoparticles on a polylactic acid/chitosan (PLA/Cs) nanocomposite scaffold. Materials and Methods In this experimental study, the nanocomposite was prepared through an electrospinning method and hWJMSCs were isolated through an explant technique. The morphology and the cell viability were evaluated by scanning electron microscopy (SEM) and 3-(4, 5- Dimethylthiazol-2)-2, 5-diphenyltetrazolium bromide (MTT) assay. Here, we present two differentiation protocols: the first one is induction with SKL2001; and the second one is with a combination of SKL2001 and zinc oxide nanoparticles (nZnO). Real-time quantitative reverse transcription (QRT-PCR) and immunocytochemistry analysis are carried out to examine the expression of specific markers in the differentiated cells. Results The nanocomposite had appropriate biocompatibility for cell adhesion and growth. While the hWJMSCs cultured on the PLA/Cs scaffolds differentiated into DE cells in the presence of SKL2001, introducing nZnO to their environment increased the differentiation process. Analyses of DE-specific markers including SOX17, FOXA2, and gooscoid (GSC) genes in mRNA level, indicated significantly high levels of expression in the SKL2001/nZnO group, followed by SKL2001 group compared to the control.
