Project description:Pluripotent stem cell-derived mesenchymal progenitor cells (PSC-MPCs) are primarily derived through two main methods: 3-dimensional (3D) embryonic body-platform (EB formation) and 2D direct differentiation method. We recently established somatic cell nuclear transfer (SCNT)-PSC lines and showed their stemness. In the present study, we produced SCNT-PSC-MPCs using a novel direct differentiation method, and the characteristics, gene expression, and genetic stability of these MPCs were compared with those derived through the EB formation method. The recovery and purification of SCNT-PSC-Direct-MPCs were significantly accelerated compared to those of the SCNT-PSC-EB-MPCs, but both types of MPCs expressed typical surface markers and exhibited similar proliferation and differentiation potentials. Additionally, the analysis of gene expression patterns using microarrays showed very similar patterns. Moreover, array CGH analysis showed that both SCNT-PSC-Direct-MPCs and SCNT-PSC-EB-MPCs exhibited no significant differences in copy number variation (CNV) or single-nucleotide polymorphism (SNP) frequency. These results indicate that SCNT-PSC-Direct-MPCs exhibited high genetic stability even after rapid differentiation into MPCs, and the rate at which directly derived MPCs reached a sufficient number was higher than that of MPCs derived through the EB method. Therefore, we suggest that the direct method of differentiating MPCs from SCNT-PSCs can improve the efficacy of SCNT-PSCs applied to allogeneic transplantation.

Project description:In this study, we derived human embryonic stem cell via SCNT. Transcriptional analysis was performed to compare characteristics of SCNT-derived ESCs to their IVF counterpart. The transcriptomes of human embryonic stem cells (hESO-NT1) derived from human skin fibroblasts (HDF-f) via somatic cell nuclear transfer (SCNT) was compared with IVF-derived counterpart (hESO-7) derived using oocytes from identical donor and parental skin fibroblast (HDF-f). . Three biological replicates of each cell line (A, B, C) were analyzed.

Project description:The exchange of the oocyte’s genome with the genome of a somatic cell, followed by the derivation of pluripotent stem cells, could enable the generation of specific cell types affected in degenerative human diseases. Such cells, carrying the patient’s genome, might be useful for cell replacement. Here we report that the development of human oocytes activated after genome exchange invariably arrests at the late cleavage stages in association with transcriptional abnormalities. In contrast, if the oocyte genome is not removed and the somatic cell genome is merely added, they efficiently develop to the blastocyst stage. Human stem cell lines derived from these blastocysts differentiate into cell types of all three germ layers, and a pluripotent gene expression program is established on the genome derived from the somatic cell. This result demonstrates the feasibility of reprogramming human cells using oocytes and identifies the removal of the oocyte genome as the primary cause of developmental failure after genome exchange. Future work should focus on the critical elements that are associated with the human oocyte genome. Stem cells were derived by reprogramming of skin cells using oocytes ('nuclear transfer') or defined factors (iPS cells), or from IVF blastocysts

Project description:Here we performed genome-wide RNA-seq and Reduced Representation Bisulfite Sequencing (RRBS-seq) in isogenic human induced pluripotent stem cells (iPSCs) and somatic cell nuclear transfer-derived embryonic stem cells (nt-ESCs), genetically matched in vitro fertilization-derived ESCs (IVF-ESCs), and their respective differentiated cells (cardiomyocytes and endothelial cells). We generated the transcriptome and DNA methylome map in human pluripotent stem cells and their differentiated cells with single-nucleotide resolution. We compared the genetic (genetic makeup) and epigenetic (reprogramming approach) influence on the gene expression and DNA methylation profiles and found that genetic composition is the major contributor of the transcriptional and epigenetic variances observed in the undifferentiated and differentiated cells originated from different reprogramming mechanisms.

Project description:Human pluripotent stem cells can be derived from somatic cells by forced expression of defined factors, and more recently by nuclear-transfer into human oocytes, revitalizing a debate on whether one reprogramming approach might be advantageous over the other. Here we compared the genetic and epigenetic stability of human nuclear-transfer embryonic stem cell (NT-ESC) lines and isogenic induced pluripotent stem cell (iPSC) lines, derived from the same somatic cell cultures of fetal, neonatal and adult origin. Both cell types shared similar genome-wide gene expression and DNA methylation profiles. Importantly, NT-ESCs and iPSCs have comparable numbers of de novo coding mutations but significantly higher than parthenogenetic ESCs. Similar to iPSCs NT-ESCs displayed clone- and gene-specific aberrations in DNA methylation and allele-specific expression of imprinted genes, similarly to iPSCs. The occurrence of these genetic and epigenetic defects in both NT-ESCs and iPSCs suggests that they are inherent to reprogramming, regardless of the underlying technique. RNA sequencing analysis was performed on a total of 12 human cell lines, including: an isogenic set of 3 nuclear-transfer embryonic stem cell (NT-ESC) lines, 2 RNA-reprogrammed induced pluripotent stem cell (iPSC) lines and their parental neonatal fibroblast cell line; an isogenic set of 1 NT-ESC line, 3 iPSC lines and their parental adult fibroblast cell line (derived from a type 1 diabetic subject); as well as 1 control embryonic stem cell (ESC) line.
