Illumina Genome Analyzer II
Description
To investigate the molecular mechanism which caused the defect of aberrant somatic cell differentiation in Wt1-deficient gonads, the differentially expressed genes between control and Wt1-deficient gonads at E11.5 was analyzed by RNA Seq analysis.After tamoxifen injection at E9.5, total RNA was prepared from control and Wt1-deficient gonads at E11.5 using RNeasy Minikit (Ambion, Austin, TX). Gonads of the same genotype (about 12 pairs each) were pooled together. For RNA-Seq, the main reagents and instruments used for RNA library construction and deep sequencing were the Illumina Gene Expression Sample Prep Kit, Solexa Sequencing Chip (flowcell), Illumina Cluster Station and Illumina HiSeq 2000 System. Sequence tags were prepared using the Illumina Digital Gene Expression Tag Profiling Kit, according to the manufacturer's protocol. Raw data was filtered to remove adaptor tags, low quality tags, and tags with a single copy number. Paired-end reads were mapped to the mouse genome (mm9) with TopHat and further analyzed by Cufflinks-Cuffdiff (Trapnell et al., 2009; Trapnell et al., 2010) pipelines to identify differentially expressed transcripts (DETs) between control and Wt1-deficient gonads.

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
nulliparous cd1 female mice were mated. Twenty four hours after detecting hte vaginal plug , the animals were laparatomized and the uterine lumen were transiently-transfected with plasmid harboring HOXA10 or control. Forty eight hours later, the uteri were morcellated in trizol and the RNA was extracted per Trizol protocol. Total RNA was then submitted for microarray analysis

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Background: In vitro culture of preimplantation mouse embryos is associated with changes in gene expression. It is however not known if the method of fertilization affects the global pattern of gene expression. Method: We compared gene expression and development of mouse blastocysts produced by intra-cytoplasmic sperm injection and cultured in Whittens medium (ICSIWM) or KSOM medium with amino acids (ICSIKSOMaa) with control blastocysts flushed out of the uterus on post coital day 3.5 (In vivo). Global pattern of gene expression was assessed using the Affymetrix 430 2.0 chip. In addition we compared gene expression in embryos generated in IVF or ICSI using WM. Results: Blastocysts resulting from ICSI fertilization have a reduction in the number of trophoblastic and inner cell mass cells compared to in vivo generated embryos. Approximately 1000 genes are different between ICSI blastocyst and in vivo blastocysts; proliferation, apoptosis and morphogenetic pathways are the most common pathways altered after in vitro culture. Unexpectedly, only 41 genes were statistically different between embryo cultured in suboptimal conditions (WM) or optimal conditions (KSOMaa). Conclusion: The method of fertilization plays a more important role in shaping the transcriptome of the developing mouse embryo than the culture media used.

Description
We have derived hESC from biopsied blastomeres of cleavage stage embryos under virtually the same conditions we used for the derivation of hESC lines from inner cell mass of blastocyst stage embryos. Blastomere-derived hESC lines exhibited all the standard characteristics of hESC including undifferentiated proliferation, genomic stability, expression of pluripotency markers and the ability to differentiate into the cells of all three germ layers both in vitro and in vivo. To examine whether hESC lines derived from two developmental stages of the embryo differ in gene expression, we have subjected three blastomere-derived hESC lines and two ICM-derived hESC lines grown under identical culture conditions to transcriptome analysis using gene expression arrays. Unlike previously reported comparisons of hESC lines which demonstrated, apart from core hESC-associated pluripotency signature, significant variations in gene expression profiles of different lines, our data show that hESC lines derived and grown under well-controlled defined culture conditions adopt nearly identical gene expression profiles. Moreover, blastomere-derived and ICM-derived hESC exhibited very similar transcriptional profiles independent of the developmental stage of the embryo from which they originated. Furthermore, this profile was evident in very early passages of the cells and did not appear to be affected by extensive passaging. These results suggest that during derivation process cells which give rise to hESC acquire virtually identical stable phenotype and are not affected by the developmental stage of the starting cell population.
