    Abstract The MUSIe002-A cell line was established from in vitro fertilization of human sperm and oocytes donated for research with informed consent. This cell line exhibited normal human embryonic stem cell (hESC) characteristics, including typical cell morphology, expression of all pluripotent stem cell markers, and potential to differentiate into three germ layers. A karyotyping analysis revealed 46 XY chromosome and cells that did not have mycoplasma contamination. MUSIe002-A represents a valuable unlimited cell source and is of potential interest for human in vitro stem cell based-models, genetic modifications, and stem cell-based therapy of human disease.

    Abstract In mammals, there are a number of kinases, including serine/threonine-protein kinase LATS1, that act as a core kinase of the Hippo pathway and that negatively regulate the Hippo effector protein YAP and its paralog TAZ. Using CRISPR/Cas9 technology, we established a stable LATS1 knockdown (LATS1-KD) iPSC from the MUSIi012-A cell line. The LATS1-KD iPSC MUSIi012-A-3 that was developed maintained both the normal karyotype and the pluripotent phenotype, and retained the ability to differentiate into all three embryonic germ layers.

    Abstract MUSIe001-A cell line was derived from a Southeast Asian (SEA) type deletion α0-thalassemia embryo. The SEA deletion embryo was donated for research with informed consent. This cell line shows normal hESC morphology, expresses all pluripotent markers, and has the potential to differentiate into all three germ layers in vitro and in vivo. The MUSIe001-A line has normal karyotype and is free from mycoplasma contamination. PCR analysis confirmed the MUSIe001-A cell line to be a SEA type deletion. MUSIe001-A is a valuable proof of principle model for gene therapy that will facilitate the development of new treatments for affected foetuses.

    Abstract Human induced pluripotent stem cells (hiPSCs) derived from dermal fibroblasts having wild type (WT) SCN5A were engineered by CRISPR/Cas9-mediated genome editing to harbor a specific point mutation (C2204>T) in SCN5A, which results in a substitution of the WT alanine by valine at codon 735 (A735V). The established MUSli009-A-1 hiPSC line has a homozygous C2204>T mutation on exon 14 of SCN5A that was confirmed by DNA sequencing analysis. The cells exhibited normal karyotype, expressed pluripotent markers and retained its capability to differentiate into three germ layers. The cardiomyocytes derived from this line would be a useful model for investigating cardiac channelopathy.

    Abstract Abstract Background Due to their extensive self-renewal and multilineage differentiation capacity, human embryonic stem cells (hESCs) have great potential for studying developmental biology, disease modeling, and developing cell replacement therapy. The first hESC line was generated in 1998 by culturing inner cell mass (ICM) cells isolated from human blastocysts using an immunosurgery technique. Since then, many techniques including mechanical ICM isolation, laser dissection, and whole embryo culture have been used to derive hESC lines. However, the hESC derivation efficiency remains low, usually less than 50%, and it requires a large number of human embryos to derive a significant number of hESC lines. Due to a shortage of and restricted access to human embryos, a novel approach with better hESC derivation efficiency is badly needed to decrease the number of embryos used. Methods We hypothesized that the low hESC derivation efficiency might be due to extensive proliferation of trophoblast (TE) cells which could interfere with ICM proliferation. We therefore developed a methodology to minimize TE cell proliferation by culturing ICM in a feeder-free system for 3 days before transferring them onto feeder cells. Results This minimized trophoblast cell proliferation (MTP) technique could be successfully used to derive hESCs from normal, abnormal, and frozen–thawed embryos with better derivation efficiency of more than 50% (range 50–100%; median 70%). Conclusions We successfully developed a better hESC derivation methodology using the “MTP” culture system. This methodology can be effectively used to derive hESCs from both normal and abnormal embryos under feeder-free conditions with higher efficiency when compared with other methodologies. With this methodology, large-scale production of clinical-grade hESCs is feasible.

    Abstract Suitable diet for cancer survivors remains an unresolved challenge. Increased glucose utilization is a hallmark of various cancers. Therefore, alternative carbohydrate supplying normal tissue but retarding cancer growth is needed. This study investigated the effect of sugar alcohols on the proliferation of oral cancer cells compared to nontransformed cells and explored the mechanism. Six oral squamous cell carcinoma (CAL-27, FaDu, SCC4, SCC9, SCC15, and SCC25) and one nontransformed oral keratinocyte (OKF6/TERT2) lines were cultured in media containing 1 mg/ml glucose and 5.8 mg/ml xylitol or sorbitol, yielding equal energy input to control group (4.5 mg/ml glucose). Partial substitution of glucose with sugar alcohols especially xylitol significantly suppressed proliferation of oral cancer but not nontransformed cells. Despite the addition of isocaloric quantities of the sugars, cancer cells exposed to low glucose plus xylitol had retarded ATP generation and decreased activity of phosphofructokinase (PFK), the rate-limiting enzyme in glycolysis. Furthermore, D-xylulose, its key metabolic intermediate, enhanced the anticancer effect of xylitol. These findings suggested a selective anticancer activity of xylitol and the potential mechanism involving inhibition of glucose utilization. Partial substitution of glucose with xylitol may be a proper nutrient for oral cancer survivors, deserving further investigation in animal and clinical settings.

    Abstract Inflammatory mediators produced during inflammatory response play an important role on pathological development of several chronic diseases. Although several dietary plants exhibited anti-inflammatory property, their impacts as a whole food has been rarely reported. The aim of the present study is to assess anti-inflammatory activity of an ethanol extract from a whole food namely “ready to eat stir-fry chicken with green curry” consisting of green curry paste, big egg plant, pea egg plant, red chili, kaffer lime and sweet basil as plant-based ingredients. The food extract at 55 - 220 μg/ml was incubated with RAW264.7 murine macrophage cells prior to stimulation with lipopolysaccharide (LPS) for 24 h. Inflammatory mediators [(inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor (TNF-α) and interleukine-6 (IL-6)] mRNA and protein were determined by RT-PCR, immunoblot and ELISA respectively. The modulation mechanism by the food extract was observed by measuring the phosphorylated form of mitogen activated protein kinases (MAPKs) and inhibitor kappa B alpha (IκB-α). The ready to eat stir-fry chicken with green curry extract significantly suppressed LPS-induced iNOS, COX-2, IL-6 and TNF-α gene expression in a dose-depend- ent manner without cytotoxicity. The suppressive effect was modulated partly by inhibiting phosphorylation of MAPKs and IκB-α. These results indicate that spices and vegetables in a complex diet still possess strong anti-inflammatory activities which warrant confirming such activities to ameliorate the pathogenesis of inflammatory-associated chronic diseases in vivo.
