Project description:CGH analysis of androgenetic haploid embryonic stem cells
| PRJNA170766 | ENA
Project description:We reported a kind of new haploid embryonic stem cell, human haploid androgenetic embryonic stem cell, which kept the sperm characteristic epigenetic modification patterns for imprinting genes. In this study, two human haploid androgenetic embryonic stem cell lines (ha-AGHESC) and two human haploid parthenogenetic embryonic stem cell lines (ha-PGHESC) with somatic control and diploid HESC control, were processed with RNA-sequencing (RNA-seq) and whole genome bisulfite sequencing (WGBS). We showed that the reconstructed semi-clone HESCs were similar to the diploid HESC in transcriptome and the methylome especially related to the known human imprinting genes. The raw data of WGBS and bulk RNA-seq are deposited at Genome Sequence Archive (GSA) of Human with accession number HRA004100.

Project description:Haploid cells are amenable for genetic analysis because they contain only one set of chromosomes.Here,we report the derivation of haESCs from androgenetic blastocysts. These cells, which we designated AG-haESCs, express classical ESC markers, are pluripotent, and contribute to various tissues including the germline upon injection into diploid blastocysts. We used microarrays to compare the gene expression levels among androgenetic haploid embryonic stem cell lines(AG-haESC) E14 and male mouse embryonic fibroblasts (MEFs) and identified that most paternally imprinted genes were down-regulated and the maternally imprinted genes were up-regulated.

To avoid the influence of diploidized cells on the expression profile, we collected samples from FACS of cells at G1/G0 stage by staining Hochest 33342. We used E14,which was a male embryonic stem cell lines, and MEFs isloated from male individuals as control. Gene expression profiles of all the cell lines were analysed on an Affymetrix GeneChip 430 2.0 array.

Project description:Comparative genomic hybridization (CGH) analysis of androgenetic haploid embryonic stem cells was done with 129/Sv male mouse kidney genomic DNA as reference. The results revealed no consistent copy number variations (CNVs) among the examined cell lines (AH129-5, AH129-N1 and AH129-NC1), except for the global difference on the X chromosome to the male control.
