Abstract
Spinal cord injury (SCI) causes inflammation and neuronal degeneration, resulting in functional movement loss. Since the availability of SCI treatments is still limited, stem cell therapy is an alternative clinical treatment for SCI and neurodegenerative disorders. Human umbilical cord Wharton's jelly-derived mesenchymal stem cells (hWJ-MSCs) are an excellent option for cell therapy. This study aimed to induce hWJ-MSCs into neural stem/progenitor cells in sphere formation (neurospheres) by using neurogenesis-enhancing small molecules (P7C3 and Isx9) and transplant to recover an SCI in a rat model. Inducted neurospheres were characterized by immunocytochemistry (ICC) and gene expression analysis. The best condition group was selected for transplantation. The results showed that the neurospheres induced by 10 µM Isx9 for 7 days produced neural stem/progenitor cell markers such as Nestin and β-tubulin 3 through the Wnt3A signaling pathway regulation markers (β-catenin and NeuroD1 gene expression). The neurospheres from the 7-day Isx9 group were selected to be transplanted into 9-day-old SCI rats. Eight weeks after transplantation, rats transplanted with the neurospheres could move normally, as shown by behavioral tests. MSCs and neurosphere cells were detected in the injured spinal cord tissue and produced neurotransmitter activity. Neurosphere-transplanted rats showed the lowest cavity size of the SCI tissue resulting from the injury recovery mechanism. In conclusion, hWJ-MSCs could differentiate into neurospheres using 10 µM Isx9 media through the Wnt3A signaling pathway. The locomotion and tissue recovery of the SCI rats with neurosphere transplantation were better than those without transplantation.

Abstract
Corneal epithelium, the outmost layer of the cornea, comprises corneal epithelial cells (CECs) that are continuously renewed by limbal epithelial stem cells (LESCs). Loss or dysfunction of LESCs causes limbal stem cell deficiency (LSCD) which results in corneal epithelial integrity loss and visual impairment. To regenerate the ocular surface, transplantation of stem cell-derived CECs is necessary. Human Wharton’s jelly derived mesenchymal stem cells (WJ-MSCs) are a good candidate for cellular therapies in allogeneic transplantation. This study aimed to test the effects of treatments on three signaling pathways involved in CEC differentiation as well as examine the optimal protocol for inducing corneal epithelial differentiation of human WJ-MSCs. All-trans retinoic acid (RA, 5 or 10 µM) inhibited the Wnt signaling pathway via suppressing the translocation of β-catenin from the cytoplasm into the nucleus. SB505124 downregulated the TGF-β signaling pathway via reducing phosphorylation of Smad2. BMP4 did not increase phosphorylation of Smad1/5/8 that is involved in BMP signaling. The combination of RA, SB505124, BMP4, and EGF for the first 3 days of differentiation followed by supplementing hormonal epidermal medium for an additional 6 days could generate corneal epithelial-like cells that expressed a CEC specific marker CK12. This study reveals that WJ-MSCs have the potential to transdifferentiate into CECs which would be beneficial for further applications in LSCD treatment therapy.

Abstract
Domestic pigs have become increasingly popular as a model for human diseases such as neurological diseases. Drug discovery platforms have increasingly been used to identify novel compounds that combat neurodegeneration. Currently, bioactive molecules such as melatonin have been demonstrated to offer a neuroprotective effect in several studies. However, a neurodegenerative platform to study novel compounds in a porcine model has not been fully established. In this study, characterized porcine induced neural stem cells (iNSCs) were used for evaluation of the protective effect of melatonin against chemical and pathogenic stimulation. First, the effects of different concentrations of melatonin on the proliferation of porcine iNSCs were studied. Second, porcine iNSCs were treated with the appropriate concentration of melatonin prior to induced degeneration with dimethyl sulfoxide or Zika virus (ZIKV). The results demonstrated that the percentages of Ki67 expression in porcine iNSCs cultured in 0.1, 1, and 10 nM melatonin were not significantly different from that in the control groups. Melatonin at 1 nM protected porcine iNSCs from DMSO-induced degeneration, as confirmed by a dead cell exclusion assay and mitochondrial membrane potential (ΔΨm) analysis. In addition, pretreatment with melatonin reduced the percentage of dead porcine iNSCs after ZIKV infection. Melatonin increased the ΔΨm, resulting in a decrease in cell degeneration. However, pretreatment with melatonin was unable to suppress ZIKV replication in porcine iNSCs. In conclusion, the present study demonstrated the anti-degenerative effect of melatonin against DMSO- and ZIKV-induced degeneration in porcine iNSCs.

Abstract
Transportation of mesenchymal stem cells (MSCs) under hypothermic conditions in 0.9% normal saline solution (NSS) might increase cell death and alter the stemness of MSCs. The present study aimed to evaluate the effect of proline-based solution (PL-BS) on cell viability and the stemness of newly established canine adipose-derived mesenchymal stem cells (cAD-MSCs) under hypothermic conditions. Characterized cAD-MSCs were stored in 1, 10, and 100 mM PL-BS or NSS at 4°C for 6, 9, and 12 hours prior to an evaluation. The results demonstrated that storage in 1 mM PL-BS for 6 hours decreased cell apoptosis and proliferation ability, but improved cell viability and mitochondrial membrane potential. cAD-MSCs maintained their high expression of CD44 and CD90, but had a low expression of CD34 and MHC class II. Trilineage differentiation ability of cAD-MSCs was not affected by storage in 1 mM PL-BS. Gene expression analysis demonstrated that immunomodulatory genes, including IDO, HGF, PGE-2, and IL-6, were upregulated in cAD-MSCs stored in 1 mM PL-BS. In conclusion, PL-BS can be effectively applied for storing cAD-MSCs under hypothermic conditions. These findings provide a new solution for effective handling of cAD-MSCs which might be promising for clinical applications.

Abstract
The reprogramming of cells into induced neural stem cells (iNSCs), which are faster and safer to generate than induced pluripotent stem cells, holds tremendous promise for fundamental and frontier research, as well as personalized cell-based therapies for neurological diseases. However, reprogramming cells with viral vectors increases the risk of tumor development due to vector and transgene integration in the host cell genome. To circumvent this issue, the Sendai virus (SeV) provides an alternative integration-free reprogramming method that removes the danger of genetic alterations and enhances the prospects of iNSCs from bench to bedside. Since pigs are among the most successful large animal models in biomedical research, porcine iNSCs (piNSCs) may serve as a disease model for both veterinary and human medicine. Here, we report the successful generation of piNSC lines from pig fibroblasts by employing the SeV. These piNSCs can be expanded for up to 40 passages in a monolayer culture and produce neurospheres in a suspension culture. These piNSCs express high levels of NSC markers (PAX6, SOX2, NESTIN, and VIMENTIN) and proliferation markers (KI67) using quantitative immunostaining and western blot analysis. Furthermore, piNSCs are multipotent, as they are capable of producing neurons and glia, as demonstrated by their expressions of TUJ1, MAP2, TH, MBP, and GFAP proteins. During the reprogramming of piNSCs with the SeV, no induced pluripotent stem cells developed, and the established piNSCs did not express OCT4, NANOG, and SSEA1. Hence, the use of the SeV can reprogram porcine somatic cells without first going through an intermediate pluripotent state. Our research produced piNSCs using SeV methods in novel, easily accessible large animal cell culture models for evaluating the efficacy of iNSC-based clinical translation in human medicine. Additionally, our piNSCs are potentially applicable in disease modeling in pigs and regenerative therapies in veterinary medicine.

Abstract
In a feeder-dependent culture system of human pluripotent stem cells (hPSCs), coculture with mouse embryonic fibroblasts may limit the clinical use of hPSCs. The aim of this study was to determine the feasibility of using human Caesarean scar fibroblasts (HSFs) as feeder cells for the culture of hPSCs. HSFs were isolated and characterised and cocultured with hPSCs, and the pluripotency, differentiation ability and karyotypic stability of hPSCs were determined. Inactivated HSFs expressed genes (including inhibin subunit beta A (INHBA), bone morphogenetic protein 4 (BMP4), fibroblast growth factor 2 (FGF2), transforming growth factor-β1 (TGFB1), collagen alpha-1(I) (COL1A1) and fibronectin-1 (FN1) that have been implicated in the maintenance of hPSC pluripotency. When HSFs were used as feeder cells, the pluripotency and karyotypic stability of hPSC lines did not change after prolonged coculture. Interestingly, exogenous FGF2 could be omitted from the culture medium when HSFs were used as feeder cells for hESCs but not hiPSCs. hESCs cocultured with HSF feeder cells in medium without FGF2 supplementation maintained their pluripotency (as confirmed by the expression of pluripotency markers and genes), differentiated invitro into embryonic germ layers and maintained their normal karyotype. The present study demonstrates that HSFs are a novel feeder cell type for culturing hPSCs and that supplementation of exogenous FGF2 is not necessary for the Chula2.hES line.

Abstract
BACKGROUND Mesenchymal stem cells (MSCs) can be derived from several tissues such as bone marrow, placenta, adipose tissue, or endometrial tissue. MSCs gain a lot of attention for cell-based therapy due to their characteristics including differentiation ability and immunomodulatory effect. Preclinical and clinical studies demonstrated that MSCs can be applied to treat female infertility by improving of the functions of ovary and uterus. This mini- review focuses on the current study of treatment of endometrial infertility by using MSCs. METHODS The present study performed a literature review focusing on the effect of MSCs for treatment of women infertility caused by endometrial dysfunction. RESULTS Bone marrow-, umbilical cord-, adipose-, amniotic-, and menstruation-derived MSCs enhance endometrial cell proliferation, injury repairs as well as reducing scar formation. The beneficial mechanism probably via immunomodulatory, cell differentiation, stimulates endometrial cell proliferation and down-regulation of fibrosis genes. The major advantage of using MSCs is to improve endometrial functions resulting in increased implantation and pregnancy. CONCLUSIONS MSCs exhibit a potential for endometrial infertility treatment. Adipose- and menstruation-derived stem cells show advantages over other sources because the cells can be derived easily and do not causes graft rejection after autologous transplantation.

Abstract
Two clones of human induced pluripotent stem cells (iPSCs) were generated from dermal fibroblasts isolated from a one-year-old Thai patient with X-linked osteogenesis imperfecta. The patient harbored a mutation, p.N459S, in the MBTPS2 gene. The cells were reprogrammed using an integration-free Sendai virus containing KLF4, c-MYC, OCT4 and SOX2. Both of the established iPSC lines (MDCUi001-A and MDCUi001-B) maintained normal karyotype, expressed pluripotent markers and differentiated into all three germ layers.

Abstract
Lentiviral vectors have emerged as the most efficient system to stably transfer and insert genes into cells. By adding a tetracycline (Tet)-inducible promoter, transgene expression delivered by a lentiviral vector can be expressed whenever needed and halted when necessary. Here we have constructed a doxycycline (Dox)-inducible lentiviral vector which efficiently introduces a designed zinc finger protein, 2-long terminal repeat zinc-finger protein (2LTRZFP), into hematopoietic cell lines and evaluated its expression in pluripotent stem cells. As a result this lentiviral inducible system can regulate 2LTRZFP expression in the SupT1 T-cell line and in pluripotent stem cells. Using this vector, no basal expression was detected in the T-cell line and its induction was achieved with low Dox concentrations. Remarkably, the intracellular regulatory expression of 2LTRZFP significantly inhibited HIV-1 integration and replication in HIV-inoculated SupT1 cells. This approach could provide a potential tool for gene therapy applications, which efficiently control and reduce the side effect of therapeutic genes expression.

Abstract
To achieve in creating permanent shrimp cell lines, cellular arrest of primary cells in the culture is needed to be firstly solved. Considering the insertion of some markers affecting cellular proliferation into primary haemocytes in order to produce the black tiger shrimp cell line and the very low percent of transduced cells previously reported in penaeid shrimps, these paved us the way to set up suitable gene delivery protocols to increase percent of transduced cells in the shrimp as our primary aim. In this study, electroporation and lipofection were used to transfer construct plasmids (pLL3.7 plasmids containing CMV promoters and pGL-IE1-126(A)-EGFP plasmids carrying WSSV IE1 promoters) into primary haemocytes. As it was difficult to distinguish between cells expressing EGFP signal and auto-fluorescence of many dead cells occurred by electroporation during the first 72 h of experiment; so, only lipofection was managed to deliver plasmids into primary cells. Surprisingly, numbers of suspected proliferative cells were derived after electroporation with no insertion of immortalising markers. These cells survived in vitro for up to 45 days with high rate of cell viability, but the number of viable cells decreased throughout the experiment. In addition, these cells expressed genes and proteins closely related to hyaline cells determined using RT-PCR and western blot. For the lipofection experiment, no green fluorescence signal was detected in any primary cell introduced with these plasmids, suggesting that plasmids were not successfully inserted into cells. Also, a number of primary haemocytes had the apoptotic cell death characteristic within 5 days after lipofection. These possibly result from using inappropriate lipofection protocol and chemical substances. In summary, finding out suitable protocols to elevate the percent of transduced cells is still necessary. Additionally, continuous shrimp cell lines would be possibly established by transforming suspected proliferative cells derived from electroporation in this study.

Abstract
This article summarizes the recent activity of the International Stem Cell Banking Initiative (ISCBI) held at the California Institute for Regenerative Medicine (CIRM) in California (June 26, 2016) and the Korean National Institutes for Health in Korea (October 19-20, 2016). Through the workshops, ISCBI is endeavoring to support a new paradigm for human medicine using pluripotent stem cells (hPSC) for cell therapies. Priority considerations for ISCBI include ensuring the safety and efficacy of a final cell therapy product and quality assured source materials, such as stem cells and primary donor cells. To these ends, ISCBI aims to promote global harmonization on quality and safety control of stem cells for research and the development of starting materials for cell therapies, with regular workshops involving hPSC banking centers, biologists, and regulatory bodies. Here, we provide a brief overview of two such recent activities, with summaries of key issues raised. Stem Cells Translational Medicine 2017;6:1956-1962.

Abstract
Abstract
Background: Human embryonic stem (hES) cells are pluripotent, and can differentiate into three germ layers. Traditionally, cultures of hES cells are maintained in a system containing mouse embryonic fibroblasts as a feeder layer for support of undifferentiated growth. However, contamination by animal cells limits the use of hES cells.
Objective: We evaluated the use of human dental pulp stem cells (hDPSCs) as a feeder layer for hES cell culture. It should be possible to obtain a new source of human mesenchymal stem cells for feeder cells to maintain undifferentiated growth of hES cells.
Methods: hDPSCs from removed impacted wisdom teeth (third molars) were extracted, cultured, and characterized for mesenchymal stem cell properties. Furthermore, hDPSCs were used as a feeder layer for culturing Chula2 and Chula5 hES cell lines. Finally, hES cell lines grown on hDPSCs feeders were examined embryonic stem cell properties.
Results: We found that hDPSCs, which have mesenchymal properties, can support undifferentiated growth of hES cell lines. After prolonged culture (passage 17), these hES cell lines still maintain ES cell properties including typical morphology seen in hES cells, the expression of pluripotency markers (Oct4, Sox2, Nanog, Rex1, SSEA-3, SSEA-4, TRA-1-60, and TRA-1-81), embryoid body formation and retention of a normal karyotype.
Conclusion: hDPSCs, derived from the pulp tissue of impacted third molars, are a potential source of human feeder cells for the culture of undifferentiated hES cells.

Abstract
Because the diploid human embryonic stem cells (hESCs) can be successfully derived from tripronuclear
zygotes thus, they can serve as an alternative source of derivation of normal karyotype hESC lines. The aim of
the present study was to compare the pluripotency and trophoblast differentiation ability of hESCs derived
from tripronuclear zygotes and diploid hESCs. In the present study, a total of 20 tripronuclear zygotes were
cultured; 8 zygotes developed to the blastocyst stage and 1 hESC line was generated. Unlike the previous
studies, chromosomal correction of tripronuclear zygotes during derivation of hESCs did not occur. The
established line carries 3 sets of chromosomes and showed a numerical aberration. Although the cell line
displayed an abnormal chromosome number, it was found the cell line has been shown to be pluripotent with the
ability to differentiate into 3 embryonic germ layers both in vitro and in
vivo. The expression of X inactive specific transcript (XIST) in mid-passage (passage 42) of
undifferentiated triploid hESCs was detected, indicating X chromosome inactivation of the cell line. Moreover,
when this cell line was induced to differentiate toward the trophoblast lineage, morphological and functional
trophoblast cells were observed, similar to the diploid hESC line.

Abstract
To reduce the cost of cytokines and growth factors in stem cell research, a simple method for the production of soluble and biological active human basic fibroblast growth factor (hbFGF) fusion protein in <i>Escherichia coli</i> was established. Under optimal conditions, approximately 60-80 mg of >95% pure hbFGF fusion proteins (Trx-6xHis-hbFGF and 6xHis-hbFGF) were obtained from 1 liter of culture broth. The purified hbFGF proteins, both with and without the fusion tags, were biologically active, which was confirmed by their ability to stimulate proliferation of NIH3T3 cells. The fusion proteins also have the ability to support several culture passages of undifferentiated human embryonic stem cells and induce pluripotent stem cells. This paper describes a low-cost and uncomplicated method for the production and purification of biologically active hbFGF fusion proteins.

Abstract
Central nervous system (CNS) dysfunction caused by neurovirulent influenza viruses is a dreaded complication of infection, and may play a role in some neurodegenerative conditions, such as Parkinson-like diseases and encephalitis lethargica. Although CNS infection by highly pathogenic H5N1 virus has been demonstrated, it is unknown whether H5N1 infects neural progenitor cells, nor whether such infection plays a role in the neuroinflammation and neurodegeneration. To pursue this question, we infected human neural progenitor cells (hNPCs) differentiated from human embryonic stem cells in vitro with H5N1 virus, and studied the resulting cytopathology, cytokine expression, and genes involved in the differentiation. Human embryonic stem cells (BG01) were maintained and differentiated into the neural progenitors, and then infected by H5N1 virus (A/Chicken/Thailand/CUK2/04) at a multiplicity of infection of 1. At 6, 24, 48, and 72 hours post-infection (hpi), cytopathic effects were observed. Then cells were characterized by immunofluorescence and electron microscopy, supernatants quantified for virus titers, and sampled cells studied for candidate genes.The hNPCs were susceptible to H5N1 virus infection as determined by morphological observation and immunofluorescence. The infection was characterized by a significant up-regulation of TNF-α gene expression, while expressions of IFN-α2, IFN-β1, IFN-γ and IL-6 remained unchanged compared to mock-infected controls. Moreover, H5N1 infection did not appear to alter expression of neuronal and astrocytic markers of hNPCs, such as β-III tubulin and GFAP, respectively. The results indicate that hNPCs support H5N1 virus infection and may play a role in the neuroinflammation during acute viral encephalitis.

Abstract
Wiskott-Aldrich syndrome (WAS) is an X-linked recessive disorder characterised by microthrombocytopenia, complex immunodeficiency, autoimmunity, and haematologic malignancies. It is caused by mutations in the gene encoding WAS protein (WASP), a regulator of actin cytoskeleton and chromatin structure in various blood cell lineages. The molecular mechanisms underlying microthrombocytopenia caused by WASP mutations remain elusive. Murine models of WASP deficiency exhibited only mild thrombocytopenia with normal-sized platelets. Here we report on the successful generation of induced pluripotent stem cell (iPSC) lines from two patients with different mutations in WASP (c.1507T>A and c.55C>T). When differentiated into early CD34+ haematopoietic and megakaryocyte progenitors, the WAS-iPSC lines were indistinguishable from the wild-type iPSCs. However, all WAS-iPSC lines exhibited defects in platelet productionin vitro. WAS-iPSCs produced platelets with more irregular shapes and smaller sizes. Immunofluorescence and electron micrograph showed defects in cytoskeletal rearrangement, F-actin distribution, and proplatelet formation. Proplatelet defects were more pronounced when using culture systems with stromal feeders comparing to feeder-free culture condition. Overexpression of WASP in the WAS-iPSCs using a lentiviral vector improved proplatelet structures and increased the platelet size. Our findings substantiate the use of iPSC technology to elucidate the disease mechanisms of WAS in thrombopoiesis.

Abstract
Human neural progenitor cells (hNPCs) are the starting material required for neuronal subtype differentiation. Proliferation of hNPCs allows researchers to study the mechanistic complexities and microenvironments present during neural differentiation and to explore potential applications for hNPCs in cell therapies. The use of enzymatic dissociation during hNPC proliferation causes dissociation-induced apoptosis; therefore, in the present study, we examined the effect of the p-160-Rho-associated coiled-coil kinase (ROCK) inhibitor Y-26732 on dissociation-induced apoptosis of hNPCs. We generated hNPCs via embryoid body formation using serum-free culture medium supplemented with noggin. The established hNPCs were characterized and the effect of the ROCK inhibitor on hNPC dissociation was studied. We demonstrated that supplementation of the culture media with 10 μM Y-26732 efficiently reduced apoptosis of dissociated hNPCs; this supplementation was effective when the inhibitor was applied either at (i) 24 h before dissociation of the cells and at 24 h after plating the cells or (ii) at 24 h after plating of the cells only. In addition to reducing apoptosis, both supplementation conditions with Y-26732 enhanced the proliferation of dissociated hNPCs. Our findings provide the optimal time window for ROCK treatment of hNPC dissociation in respect to apoptosis and cell proliferation.

Abstract
Human embryonic stem (hES) cells are considered to be a potential source for the therapy of human diseases, drug screening, and the study of developmental biology. In the present study, we successfully derived hES cell lines from blastocysts developed from frozen and fresh embryos. Seventeen- to eighteen-year-old frozen embryos were thawed, cultured to the blastocyst stage, and induced to form hES cells using human foreskin fibroblasts. The Chula2.hES cell line and the Chula4.hES and Chula5.hES cell lines were derived from blastocysts developed from frozen and fresh embryos, respectively. The cell lines expressed pluripotent markers, including alkaline phosphatase (AP), Oct3/4, stage-specific embryonic antigen (SSEA)-4, and tumor recognition antigen (TRA)-1-60 and TRA-1-81 as detected with immunocytochemistry. The real-time polymerase chain reaction (RT-PCR) results showed that the cell lines expressed pluripotent genes, including OCT3/4, SOX2, NANOG, UTF, LIN28, REX1, NODAL, and E-Cadherin. In addition, the telomerase activities of the cell lines were higher than in the fibroblast cells. Moreover, the cell lines differentiated into all three germ layers both in vitro and in vivo. The cell lines had distinct identities, as revealed with DNA fingerprinting, and maintained their normal karyotype after a long-term culture. This study is the first to report the successful derivation of hES cell lines in Thailand and that frozen embryos maintained their pluripotency similar to fresh embryos, as shown by the success of hES cell derivation, even after years of cryopreservation. Therefore, embryos from prolonged cryopreservation could be an alternative source for embryonic stem cell research.

Abstract
Embryonic stem cells derived from nuclear transfer embryos (ntESCs) are particularly valuable for regenerative medicine, as they are a patient-specific and histocompatible cell source for the treatment of varying diseases. However, currently, little is known about their cellular and molecular profile. In the present study, in a mouse model different donor cell-derived ntESCs from various genetic backgrounds were compared with reference ESCs and analyzed comprehensively at the cellular level. A number of pluripotency marker genes were compared by flow cytometry and immunocytochemistry analysis. Significant differences at the protein level were observed for POU5F1, SOX2, FGF4, NANOG, and SSEA-1. However, such differences had no effect on in vitro cell differentiation and cell fate: derivatives of the three germ layers were detected in all ntESC lines. The neural and cardiac in vitro differentiation revealed minor differences between the cell lines, both at the mRNA and protein level. Karyotype analyses and cell growth studies did not reveal any significant variations. Despite some differences observed, the present study revealed that ntESC lines had similar differentiation competences compared to other ESCs. The results indicate that the observed differences may be related to the genotype rather than to the nuclear transfer technology.

Abstract
Pluripotent stem cells would have great potential in cell therapies and drug development when genetically matched with the patient; thus, histocompatible cells could be used in transplantation therapy or as a source of patient-specific cells for drug testing. Pluripotent embryonic stem cells (ESCs)-generated via somatic cell nuclear transfer (SCNT) or parthenogenesis (pESC)-are potential sources of histocompatible cells and tissues for transplantation. Earlier studies used the piezoelectric microinjection (PEM) technique for nuclear transfer (NT) in mouse. No specific studies examined zona-free (ZF) NT as an alternative NT method to generate genetically matched ESCs of a nuclear donor. In this study, we compared the efficiency of nuclear transfer-derived ESC (ntESC) line establishment from ZF-NT, ZF-parthenogenetic (PGA), and ZF-fertilized embryos with that of the PEM-NT method. Different nuclei donor cells [cumulus, ESC, and mouse embryonic fibroblast (MEF)] were used and the efficiency of ntESC derivation was investigated, along with their in vitro characterization. The ZF-NT method's efficiency was higher than that of the PEM-NT using cumulus cells. When ESCs and cumulus cells were used as nuclear donor cells, they resulted in significantly higher ZF-NT-derived ntESC line establishment rates compared to MEF cells. In conclusion, the nuclear donor cell type significantly affected the efficiency of ntESC line establishment, and the ZF-NT method was efficient to establish pluripotent ntESC lines.

Abstract
OBJECTIVE To establish human embryonic stem (hES) cells from human embryos. DESIGN Experimental study. SETTING Reproductive Medicine Unit, Department of Obstetrics and Gynecology, Faculty of Medicine, Chulalongkorn University. MATERIAL AND METHOD Abnormal and normal fertilization embryos were cultured in vitro until reaching blastocyst stage. Four different methods for isolation of ICMs were used. Immunosurgery, mechanical isolation, laser assists, and whole blastocyst culture were performed. The feeder layers used in the present study were fibroblasts, isolated from either mouse or human. Mechanical splitting of ICM outgrowths or hES-like cells was performed for propagation of cells. Characterization of hES-like cells was conducted by morphology, detection of immunostaining of Oct-4, and enzymatic activity of alkaline phosphatase (AP). HES-like cells were spontaneously differentiated through suspension culture of embryoid body (EB). Subsequent differentiation was done on gelatin-coated dishes. MAIN OUTCOME MEASURE Establishment of hES cells. RESULTS By using abnormal fertilization embryos, 80.0% (8/10) of blastocysts were able to attach on the feeder layers, 50% (4/8) formed ICM outgrowths, but no hES-like cells were established. By using normal fertilization embryos, 84.6% (22/26) of blastocysts were able to attach on feeder layers, 18.2% (4/22) formed ICM outgrowths. One hES-like cell line was successfully established by using mechanical isolation of ICMs and human adult skin fibroblasts as feeder layers. This hES-like cells exhibited typical morphology of hES cells, positive staining for Oct-4 and AP. hES-like cells were able to form EB and differentiated into neural-like cells. CONCLUSION This is the first report in Thailand that hES-like cells can be isolated from normal development human embryos at blastocysts-stage using mechanical isolation of ICM and culture with human adult skin fibroblast as feeder layers.

Abstract
OBJECTIVE To determine the effect of leukemia inhibitory factor (LIF) on the quality of in vitro produced mouse blastocyst and the efficiency of embryonic stem (ES) cell derivation. DESIGN Experimental study SETTING Reproductive Medicine Unit, Department of Obstetrics and Gynecology, Faculty of Medicine, Chulalongkorn University MATERIAL AND METHOD In vivo fertilized zygotes were collected and subjected to in vitro culture in potassium simplex optimized medium (KSOM) containing 1,000 unit/ml LIF. The developmental ability of the zygote to blastocyst-stage and the cell numbers in blastocysts were evaluated Expanded blastocysts developed in different culture media were subsequently subjected to ES cell derivation. MAIN OUTCOME MEASURE (s): The influence of LIF on the quality of and the total cell numbers of blastocyst developed in vitro. RESULTS Supplementation of LIF in KSOM increased the rate of hatching blastocysts (63.8% vs. 53.7%; p < 0.05) and total cell numbers (91.4 +/- 15.0 vs. 85.1 +/- 7.7; p < 0.05) compared to KSOM alone. ES cells were obtained 66.7% from blastocysts developed in KSOM-LIF versus 41.7% in KSOM (p > 0.05). Established ES cell lines showed typical colony and characteristics of pluripotent murine ES cells. CONCLUSION LIF improved the quality of in vitro produced blastocysts but not enhanced ES cell derivation.

Abstract
Mouse cloning can be performed by a direct microinjection of donor nuclei using a conventional or a piezo-actuated technique (Rybouchkin et al. 2002 Reproduction 124, 197–207; Wakayama et al. 1998 Nature 394, 369–374). However, a high percentage of lysed oocytes was observed during the pipette penetration of the cytoplasmic membrane through the zona pellucida. The aim of this experiment was to investigate the possibility of a combination of a laser-assisted zona opening and electro-fusion for mouse cloning. Mature oocytes were obtained from FSH-superovulated B6D2F1 female mice. Enucleation and transfer of donor cell were performed in HEPES-buffered CZB medium. Spindle-chromosome complexes (SCCs) together with first polar body were removed by blunt-end pipette via a small hole in the zona pellucida which was cut by a laser beam. An adult fibroblast cell was introduced into the perivitelline space and fused to the enucleated oocyte by using a single DC pulse of 1.5 kV cm-1, 20 �s, in a fusion medium (Liu and Aoki 2003 Animal Sci. J. 75, 125–129). The fusion rate was checked 30 min later and only the fused oocytes were subjected to activation by 6 h culture in Ca2+-free CZB medium supplemented with 10 mM Sr2+ and 5 �g mL-1 cytochalasin B. The oocytes which presented the pseudo-pronuclei were considered as the activated oocytes and were cultured in CZB medium at 37�C, 5% CO2 in humidified atmosphere. The developmental rate was observed every 24 h for 4 days. The diploid parthenogenetically activated embryos serving as a control were obtained using the same activation protocol but without SCC removal. The percentages of survival after enucleation and after fusion were recorded. The formation of pseudo-pronuclei and the embryos developing to a particular stage were determined by chi-square analysis. The results show that most of the oocytes survived after enucleation (92.5%, 172/186) and the fusion rate was 71.9% (105/146). The formation of pseudo-pronuclei and the cleavage rate of cloned embryos was lower than in the control (87.6% (92/105) vs. 100% (90/90) and 69.6% (64/92) vs. 92.2% (83/90), respectively). The developmental rate to morula–blastocyst stage of cloned embryos was significantly lower than in the control [1.1% (1/92) vs. 44.4% (40/90); P < 0.05]. These results indicate that using laser-assisted zona opening and electro-fusion technique is practical for mouse cloning and provides an alternative method when injection of donor nuclei into the recipient oocytes using a conventional or a piezo-driven method is technically difficult.

Abstract
Generating cloned embryos using rabbit oocytes as the recipient cytoplasm is useful for studying the interaction between a foreign donor nucleus and the recipient cytoplasm. The aims of the study were to (1) investigate the development of inter-species cloned embryos derived from rabbit oocytes, using cow (no. 1 and no. 2), swamp buffalo, pig, and elephant ear fibroblasts as donor cells, and (2) observe the developmental capacity of cloned rabbit embryos derived from adult and fetal fibroblasts. Mature oocytes were collected from superovulated rabbit does by oviductal flushing. A single fibroblast (passages 3–5) in the starvation stage (1–3 days prior to nuclear transfer) was transferred into an enucleated oocyte, which was confirmed by Hoechst staining. Reconstructed oocytes were later fused by electrical stimulation using 3 DC pulses, 3.2 kV.cm-1, for 20 �s. Fused couplets were activated by inducing the same electrical stimulation, and subsequently incubated in activation medium comprised of 5 �g mL-1 cycloheximide, 2 mM mL-1 6-DMAP and 10% fetal bovine serum (FBS), in synthetic oviduct fluid (SOF), for 1 h. They were then cultured in SOF supplemented with 10% FBS for 5 days. Differences in the percentages of fusion and embryo development to a particular stage between source of donor cells were determined by chi-square analysis. The fusion rates of cow no. 1 (62%; 82/133), cow no. 2 (54%; 41/76), buffalo (63%; 53/84), pig (69%; 60/87), elephant (59%; 44/74), adult rabbit (55%; 41/74), and fetal rabbit couplets (70%; 56/80) did not differ significantly. The cleavage rates of cows no. 1 and 2, buffalo, pig, and elephant embryos were 33%, 83%, 57%, 67%, and 100%, respectively. The rabbit fibroblasts derived from an adult gave a significantly lower cleavage rate than those derived from a fetus (54% vs. 95%) (P < 0.05). The developmental rates at morula and blastocyst of cloned embryos reconstructed from fetal rabbit fibroblasts were significantly greater than those reconstructed from adult rabbit, buffalo, pig, and elephant (morula: 39%, 12%, 4%, 7%, and 14%; blastocyst: 23%, 7%, 0%, 3%, and 9%, respectively; P < 0.05). While cow no. 2 donor cells provided a significant embryo development success rate in terms of blastocyst formation, cow no. 1 cloned embryos could not develop beyond the cleavage stage (morula: 10% vs. 0%; and blastocyst: 7% vs. 0%). In conclusion, cow, swamp buffalo, pig, and elephant fibroblasts can be produced by using enucleated rabbit oocytes as recipient cytoplasm. The developmental capacity of cloned embryos is affected by the sources and the individual ability of donor cell used, and varies according to the species.

Abstract
Cell therapy is the promising therapeutic tool for the next decade. "Regenerative Medicine" based on cell and tissue replacement therapy is proposed as a revolutionary approach to various chronic and incurable conditions. The first key step for successful cell therapy is the establishment of clinical grade human Embryonic Stem Cell (hESC) lines. This article provides a concise summary on conventional and novel methods for hESC line derivation. There is also discussion on progression, future direction and problems in hESC line development. In Thailand, more advance knowledge, skill, and technology are required to develop the first human embryonic stem cell line and step forward to make cell therapy a reality.

Abstract
Interspecies nuclear transfer is an important tool for studying the interaction between the cytoplasm of one cell and the donor nucleus of another (Chen et al. 2002 Biol. Reprod. 67, 637–642). The aim of this experiment was to investigate the possibility of developing in vitro an asian elephant cloned embryo using a rabbit recipient oocyte. The elephant donor cells were obtained from the ear skin of a stillborn Asian elephant (Elephus maximus) and the in vivo-matured recipient oocytes were obtained from FSH-stimulated New Zealand White doe rabbits. Enucleation was accomplished by aspiration of the first polar body and the metaphase II plate together with a small amount of cytoplasm. Successful enucleation was confirmed by UV examination after staining with 5 μg mL−1 Hoechst 33342. The donor cells were introduced into the perivitelline space of the enucleated oocytes immediately after enucleation. The elephant-rabbit reconstructed embryos were fused in 0.3 M manitol with 0.1 mM Ca2+ and Mg2+ using two types of electrical pulses: E1 (n = 61): 3.2 kV/cm, 3 pulses, 20 μs (Chesne et al. 2002 Nat. Biotechnol. 20, 366–369); E2 (n = 69): 2.0 kV/cm, 2 pulses, 20 μs (Chen et al. 2002 Biol. Reprod. 67, 637–642). The fused embryos were activated 1 h after fusion by electrical pulses to those used for fusion and then incubated in 5 μg mL−1 cyclohexamide and 2 mM 6-DMAP for 1 h. Subsequently, the activated embryos were cultured in B2 medium containing 2.5% fetal calf serum. The developmental rate was observed every 24 h for 7 days and the differences in the percentages of embryos developing to a particular stage were determined by chi-square analysis. The results showed that the fusion and cleavage rates of elephant-rabbit cloned embryos fused and activated by E1 were significantly higher than for E2 (P < 0.05; see Table 1). Compared with rabbit-rabbit cloned embryos using adult skin fibroblast as a donor cell and E1 for both fusion and electrical activation, we found that the cleavage and blastocyst rates of elephant-rabbit cloned embryos was higher than for the rabbit-rabbit ones (65% (28/43) versus 58% (28/48) and 7% (3/43) versus 4% (2/48) respectively). Results from this study showed that either of the electrical pulses, 3.2 kV/cm, 3 pulses, 20 μs or 2.0 kV/cm, 2 pulses, 20 μs, can be used to fuse elephant somatic cells to rabbit ooplasm and the rabbit oocytes can be served as recipient oocytes to support the development of elephant cloned embryos up to the blastocyst stage.
