Gene expression analysis in WT-AG-haESCs, DKO-AG-haESCs and round spermatids

Project description:RNA seq result shows that WT-AG-haESCs and DKO-AG-haESCs samples are clustered together using hierarchical cluster both in the all expression genes and imprinting genes. This suggests that DKO of DMRs of H19 and Gtl2 do not change the overall gene expression patterns in AG-haESCs. We used round spermatids as control. Using RNA-seq, profile of all the expression genes and imprinting genes beteween different samples were analysed.

DNA methylation profiling in WT-AG-haESCs, DKO-AG-haESCs and round spermatids

Project description:We generated RRBS data to analyse the DNA methylation profiling among WT-AG-haESCs, DKO-AG-haESCs and round spermatids, we found deletion of H19 and Gtl2 DMRs do not change the methylation patterns in AG-haESCs base on all detected CpG sites. We used round spermatids as control and analysed the DNA methylation profiles of all the cell lines were by RRBS.

CGH analysis of monkey PG-haESCs (parthenogenic haploid embryonic stem cells)

Project description:The genomic DNA sample of monkey PG-haESCs were compared to the female adipose cells by comparative genomic hybridization. The data confirmed that these haploid cells sustained genome integrity. The analysis was performed on a Agilent aCGH G3 Rhesus Macaque 4x180K array to analyse the copy number variations in monkey PG-haESCs, and the genomic DNA of femal monkey adipose was used as control, which had the same background with haploid ESCs.

CGH analysis of AG-haESCs (androgenetic haploid embryonic stem cells)

Project description:The genomic DNA sample of AG-haESCs were compared to the C57BL/6J male mouse kidney by comparative genomic hybridization. The data confirmed that the haploid cells sustained genome integrity. The analysis was performed on a NimbleGen Mouse CGH 3x720K Whole-Genome Tiling Array to analyse the copy number variations in AG-haESCs, and the genomic DNA of C57BL/6J male mouse kidney was used as control, which had the same background with haploid ESCs.

mRNA expression data from AG-haESC, E14 and MEF

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.

mRNA expression data from monkey PG-haESCs, ICSI-derived ESCs and somatic fibroblasts

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 monkey parthenogenic blastocysts. These cells, which we designated PG-haESCs (parthenogenic haploid embryonic stem cells), express classical ESC markers, are pluripotent, and can differentiate to different cell lines from all three embryonic germ layers in vivo and in vitro. We used microarrays to compare the gene expression levels among PG-haESC, ICSI-derived ESCs and female monkey somatic fibroblasts. We used ICSI-derived ESCs and somatic fibroblasts isloated from female individuals as control. Gene expression profiles of all the cell lines were analysed on an Affymetrix Rhesus Macaque array.

Expression data from rat androgenetic embryonic stem cells

Project description:The rat androgenetic embryonic stem cells (RahES cells) have only 21 chromosomes. However, they express pluripotency markers, differentiate into three germ layer cells as well as contribute to the germline as the normal diploid rat ES cells. Moreover, the RahES cells can produce fertile rats after intracytoplasmic injection into oocytes, thus are capable to transmit genetic modifications to offspring. We used microarrays to detail the global gene expression profile of RahES cells and identified distinct classes of up-regulated and down-regulated genes compared with the expression of normal diploid rat ES cells. Two different RahES cell lines, one diploid rat ES cell line and round sperm cells were selected for RNA extraction and hybridization on Affymetrix Chip.
