Cancer cells exist in a state of Darwinian selection using mechanisms that produce changes in gene expression through genetic and epigenetic alteration to facilitate their survival. Cellular plasticity, or the ability to alter cellular phenotype, can assist in survival of premalignant cells as they progress to full malignancy by providing another mechanism of adaptation. The connection between cellular stress and the progression of cancer has been established, although the details of the mechanisms have yet to be fully elucidated...

Neuropilin-1 (NRP1) is one of the members of neuropilin family. It can combine with disparate ligands involved in regulating cell proliferation, apoptosis, and differentiation. The binding of NRP1 to Sema3A stimulates osteoblast differentiation through the classical Wnt/β-catenin pathway. However, the functions of NRP1 in dental pulp stem cells (DPSCs) are not clear. The aim of our study was to investigate how NRP1 controlled odontoblast differentiation in DPSCs and clarified the underlying mechanisms. NRP1 expression was increased in time-dependent manner along with cell odontoblast differentiation...

We evaluated the suitability of 10 candidate internal control genes (ICGs), belonging to different functional classes, namely ACTB, EEF1A1, GAPDH, HPRT1, HMBS, RPS15, RPS18, RPS23, SDHA, and UBC for normalizing the real-time quantitative polymerase chain reaction (qPCR) data of blastocyst-stage buffalo embryos produced by hand-made cloning and in vitro fertilization (IVF). Total RNA was isolated from three pools, each of cloned and IVF blastocysts (n = 50/pool) for cDNA synthesis. Two different statistical algorithms geNorm and NormFinder were used for evaluating the stability of these genes...

MicroRNAs (miRNAs) with 20-30 nucleotides have recently emerged as the multidimensional regulators of cell fate decisions. Recent improvement in high-throughput sequencing has highlighted the potential role of LIN28/let-7 regulatory network in several developmental events. It was proposed that this pathway might represent a functional signature in cell proliferation, transition between commitment and pluripotency, and regulation of cancer and tumorigenicity. LIN28/let-7 regulatory pathway is one of the excellent examples of the relationship between an miRNA and mRNAs...

Somatic cell nuclear transfer (SCNT) success is partially hindered by the low epigenetic reprogramming efficiency of the donor cell. Previous studies suggest cellular heterogeneity among donor nuclei in regard to reprogramming potential, which precludes comparison among different strategies to increase cloning success. In this context, we evaluated the effect of using clonal cell populations (CPs) of bovine adult fibroblasts established by single-cell plating in SCNT. Different CPs were evaluated in regard to proliferation rate, senescence level, and chromosome stability, as well as for POU5F1 (POU class 5 homeobox 1) mRNA expression levels...

For successful cartilage tissue engineering, the ability to generate a high number of chondrocytes in vitro while avoiding terminal differentiation or de-differentiation is critical. The ability to accomplish this by using the abundant and easily sampled costal cartilage could provide a practical alternative to the use of articular cartilage and mesenchymal stem cells. Chondrocytes isolated from pig costal cartilage were expanded in either serum-free medium with FGF2 (SFM) or fetal bovine serum-containing medium (SCM), under either high (21%) or low (5%) oxygen conditions...

Emerging evidence suggests that epitranscriptional modifications influence multiple cellular processes. N6-methyladenosine (m(6)A), as the most abundant reversible methylation of mRNA, has also been reported to play critical roles in modulating embryonic stem cell differentiation and somatic cell reprogramming by regulating gene expression. This review examined the characteristics of m(6)A, including the distribution profile and currently discovered "writer," "eraser," and "reader" proteins. Moreover, the hypothesis is proposed that m(6)A could influence cell fate determination, and the underlying mechanisms are due to the related mRNA degradation, causing weakening of previous cell characteristics and eventually leading them to develop into the reverse direction (pluripotency or differentiation state)...

Yinyang1 (YY1) participates in protein-DNA, protein-RNA, and protein-protein interactions and regulates developmental processes and disease mechanisms. YY1 interactions regulate a range of important biological functions, including oocyte maturation, epithelial to mesenchymal transition, and vascular endothelial growth factor (VEGF) signaling. We tested the hypothesis that YY1 is required for inner cell mass (ICM) lineage commitment during preimplantation development. In this study, we document gene expression patterns and protein localization of key transcription factors in Yy1 global, tissue-specific, and dsRNA-mediated knockout/down embryos...

A time-lapse monitoring system has predictive value for selecting good-quality embryos with the highest implantation potential. Using this new tool, we investigated the developmental potential and developmental kinetics of bovine parthenogenetic (PA) and two types of somatic cell nuclear transfer (NT) embryos. Bovine non-transgenic ear cells (bECs) or transgenic cells (bTGCs) were used as donor cells. The cleavage and blastocyst development rates did not significantly differ among the PA, NT-bEC, and NT-bTGC groups, and first cleavage occurred an average of 19...

The differentiation of multipotent stem cells toward a pancreatic lineage provides us with an alternative cell-based therapeutic approach to type 1 diabetes and enables us to study pancreas development. The current study aims to study the effect of growth factors such as activin A or nicotinamide, alone and in combinations with the transcription factor, PDX1 (pancreatic and duodenal homeobox-1), on human amnion epithelial cells (hAECs) toward a pancreatic lineage. Ectopic expression of Pdx1 followed by treatment of hAECs with nicotinamide for 4 days resulted in strong induction of pancreatic endoderm and pancreatic progenitor genes, including NKX6...

The potential clinical applications of hematopoietic stem cells (HSCs) derived from human pluripotent stem cells (hPSCs) are limited by the difficulty of recapitulating embryoid hematopoiesis and by the unknown differentiation potential of hPSC lines. To evaluate their hematopoietic developmental potential, available hPSC lines were differentiated by an embryoid body (EB) suspension culture in serum-free medium supplemented with three different cytokine mixes (CMs). The hPSC differentiation status was investigated by the flow cytometry expression profiles of cell surface molecules, and the gene expression of pluripotency and differentiation markers over time was evaluated by real-time reverse transcription polymerase chain reaction (qRT-PCR)...

The concept of Regenerative Medicine combined with Cell based Therapy and Tissue Engineering represents the fourth pillar of healthcare and provides a promising approach for the treatment of serious diseases. Recently, cell based therapies are focused on the use of mesenchymal stem/stromal cells (MSCs). Human MSCs, that represent a mesoderm derived population of progenitors, are easily expanded in culture. They are capable to differentiate into osteoblasts, chondrocytes, and adipocytes and exhibit the potential to repair or regenerate damaged tissues...

Specific activation of endogenous genes can be achieved by programmable artificial transcription factors (ATFs). In this study, we compared two artificial, programmable, clustered regularly interspaced short palindromic repeats (CRISPR)-based, ubiquitous transcription factors: deficient CRISPR-associated protein 9 (dCas9)-VP64 (CRISPRa) alone, or a combination of dCas9-VP64 and MS2-P65-HSF1 [synergistic activation mediator (SAM) system] mediated activation of five pluripotency genes: KLF4 (K), LIN28 (L), MYC (M), OCT4 (O), and SOX2 (S) in human cells (HEK293T, HeLa, HepG2, and primary fibroblasts)...

The "Dolly" based cloning (classical nuclear transfer, [CNT]) and the handmade cloning (HMC) are methods that are nowadays routinely used for somatic cloning of large domestic species. Both cloning protocols share several similarities, but differ with regard to the required in vitro culture, which in turn results in different time intervals until embryo transfer. It is not yet known whether the differences between cloned embryos from the two protocols are due to the cloning methods themselves or the in vitro culture, as some studies have shown detrimental effects of in vitro culture on conventionally produced embryos...

The application of cloning technology on a large scale is limited by very low offspring rate primarily due to aberrant or incomplete epigenetic reprogramming. Trichostatin A (TSA), a histone deacetylase inhibitor, and 5-aza-2'-deoxycytidine (5-aza-dC), an inhibitor of DNA methyltransferases, are widely used for altering the epigenetic status of cloned embryos. We optimized the doses of these epigenetic modifiers for production of buffalo embryos by handmade cloning and examined whether combined treatment with these epigenetic modifiers offered any advantage over treatment with the individual epigenetic modifier...

Mesenchymal stem cells (MSCs) are a promising resource for stem cell therapy for the treatment of different neurodegenerative disorders. In particular, dental MSCs, given their origin from neural crest and their proneness toward neuronal differentiation, may be more suitable for transplantation. However, if MSCs can undergo spontaneous transformation and give rise to tumor is still debated. Data about transcriptional regulation of oncogenes in MSCs following in vitro expansion are not available. In this work, we compared gene expression levels of oncogenes in gingival-derived MSCs at passage number 10 and 41...

In mammals, the imprinted genes play vital roles in development and are generally controlled by DNA methylation at imprinting control regions (ICRs). Recently, it was discovered that 5-hydroxymethylcytosine (5-hmC) is a stable epigenetic modification; however, its functions in cloned animal genomes have not yet been fully elucidated. In this study, we interrogated and quantified the 5-hmC levels in the brain of cloned goats and discovered upregulation of Uhrf1 (p < 0.001), Dnmt1 (p < 0.05), Dnmt3a (p < 0...

Induced pluripotent stem cells (iPSCs) have an extensive application in regenerative medicine, pharmaceutical discovery, and basic research. With the recent derivation of rat iPSCs, it is now feasible to apply genetic manipulation in this species. But such tools do not yet exist for many rat strains, especially for disease model rat. The Sprague Dawley (SD) rat is an inbred disease model for hypertension, nephropathy, pulmonary hypertension, depression, and alcohol consumption. In this study, the SD rat iPSCs were generated using lentiviral method...

MicroRNAs (miRNAs) are posttranscriptional regulators of gene expression. They play an important role in various cellular processes such as apoptosis, differentiation, secretion, and proliferation. Embryonic stem cells (ESCs) are derived from the inner cell mass of the blastocyst stage of the embryo. miRNAs are critical factors for the self-renewal and differentiation of ESCs. In this review, we will focus on the role of miRNAs in the self-renewal and directional differentiation of ESCs. We will present the current knowledge on key points related to miRNA biogenesis and their function in ESCs...
