Project description:RNA-Seq was used to assess the gene expression profiles of 4 allodiploid embryonic stem cell lines and 4 control embryonic stem cell lines. Moreover, single-cell RNA-Seq was used to quantify the transcriptomes of 87 allodiploid single cells.

Moreover, single-cell RNA-Seq was used to quantify the transcriptomes of 87 allodiploid single cells. Comparison of mRNA profiles of 4 allodiploid embryonic stem cell lines to 4 control mouse and rat embryonic stem cell lines using the Illumina HiSeq 2000 platform. Single-cell RNA-Seq was conducted to check the transcriptomes of single allodiploid embryonic and differentiated cells.
Project description:G-banding of human embryonic stem cells (hESC) has proved their predisposition to aneuploidy of chromosomes 12, 17 and X. Now, using array-based comparative genomic hybridization, we find that hESC also accumulate other recurrent chromosomal abnormalities, such as duplications of stemness genes, submicroscopic instability of 20q11.21 and the appearance of a derivative chromosome 18. Keywords: comparative genomic hybridization, genomic integrity of human embryonic stem cells

Keywords: comparative genomic hybridization, genomic integrity of human embryonic stem cells Array-based comparative genomic hybridization was performed on 48 DNA samples from 17 human embryonic stem cell lines, all cultured in our laboratory under the same conditions. All lines were hybridized against DNA obtained from peripheral blood from donors with a known normal karyotype. No replicates were done from the same DNA sample, but, whenever possible the same stem cell line was analysed at later passages. All detected abnormalities were confirmed by FISH and/or G-banding.
