Project description:Embryonic stem (ES) cells and ES cell-derived progeny characterized by nestin expression (including neural progenitors) were studied (three independent experiments). The mouse ES cell line R1 was cultured on a feeder layer of mouse embryonic fibroblasts (FL). ES cells were differentiated into nestin-positive cells for 4+8 days and 4+11 days according to the differentiation protocol by Rolletschek et al. (Mechanisms of Development 105, 93-104, 2001). The study was performed with three independent cell cultures (= triplicates). RNA was prepared from both undifferentiated ES cells and ES cell-derived nestin-positive cells, and from fibroblast feeder cells.

Project description:Conventional conditions to maintain human embryonic stem cells (hESC) imply the use of inactive mouse embryonic fibroblast (iMEF) as a feeder layer. However, it has suggested that the culture of hESC on iMEF could be an artifact that does not correspond to the in vitro counterpart of the human epiblast. We previously derived and maintained human embryonic stem cells (Amicqui-1 hESC line) on a feeder layer of human amniotic epithelial cells (hAEC). However, the mechanisms involved in the interaction between both cell types to promote the pluripotency still remain unknown. To elucidate if the transcription profile of hESC on hAEC differs from conventional conditions on iMEF, we carried out RNA-seq of Amicqui-1 hESC on both feeder layer conditions (AMIQ hESC-iMEF and AMIQ hESC-hAEC) and on their respective conditioned media (AMIQ hESC-hAEC-CM and AMIQ hESC-iMEF-CM). In this experiment we included H1-hESC-iMEF and hAEC alone.

Project description:Background: The hES-T3 cell line with normal female karyotype was used to differentiate into autogeneic fibroblast-like cells (T3HDF) as feeder to support the undifferentiated growth of hES-T3 cells (T3/HDF) for 14 passages. A feeder-free culture on Matrigel in hES medium conditioned by these autogeneic feeder cells (T3HDF) was established to maintain the undifferentiated growth of hES-T3 cells (T3/CMHDF) for 8 passages. Results: The gene expression profiles of mRNAs, microRNAs and proteins between the undifferentiated T3/HDF and T3/CMHDF cells were shown to be very similar, and their expression profiles were also found to be similar to those of T3/MEF and T3/CMMEF cells grown on MEF feeder and feeder-free Matrigel in MEF-conditioned medium, respectively. The abundantly expressed genes of T3/HDF, T3/CMHDF, T3/MEF and T3/CMMEF cells were found to play prominent roles in signaling pathways and GO process networks. The miR-302/367 cluster and miR-371/372/373 cluster were extremely abundantly expressed in undifferentiated T3/HDF and T3/CMHDF as well as T3/MEF andT3/CMMEF cells. The undifferentiated state of T3/HDF and T3/CMHDF cells was evidenced by the very high expression levels of ¡§stemness¡¨ genes and low expression levels of differentiation markers of ectoderm, mesoderm and endoderm in addition to the strong staining of OCT4 and NANOG. Conclusion: The T3HDF feeder and T3HDF-conditioned medium were able to support the undifferentiated growth of hES cells, and they would be useful for drug development and toxicity testing in addition to the reduced risks of xenogeneic pathogens when used for medical applications such as cell therapies. Keywords: genetic modification In this investigation, both miRNA and mRNA expression profiles from human embryonic stem cells (hES-T3) grown on MEF feeder (T3_MEF), feeder-free Matrigel in MEF-conditioned medium (T3_CMMEF), T3HDF (hES-T3 differentiated fibroblast-like cells) feeder and feeder-free Matrigel in T3HDF-conditioned medium were quantitatively determined. Several target genes of T3BA and T3CM cells-specific miRNAs were identified. ***This submission represents the mRNA expression component of the study only***

Project description:Tissue from the telencephalon was isolated from E13.5 BALB/C mouse and allowed to culture as neurospheres in the presence of FGF2. These cultures were assessed for undifferentiated neural stem cells by the expression of Nestin and were found to be ~98% Nestin positive. Comparisons of these nestin positive neural stem cells will be made to R1 ES cells to identify the genes that are important in totipotent, self-renewing ES cells vs. commitment to the multipotent, self-renewing neural stem cell phenotype.
