Project description:The study is to obtain a transcriptome-wide map of prenatal murine stem and progenitor cells. VavCre+ mice were used for conditional knockout of Ddx41. Wild-type, Ddx41 heterozygous (Ddx41+/-) and Ddx41 knockout (Ddx41-/-) LSK cells from embryonic 14.5 day fetal liver were harvested (three samples from each group) for RNA. Gene expression analysis and alternative splicing analysis were performed. RNA-seq data were confirmed by RT-qPCR and regular PCR followed by gel quantification. A global change of gene expression and substantial differential splicing events were observed in KO samples compared to WT and het.
Project description:To compare the impact of hematopoietic-specific Brpf1 gene inactivation, LSK (Lin-Sca1+cKit1+) cells were sorted from wild-type and Brpf1-null fetal liver cells for RNA-Seq. Four E14.5 embryos were used to pool sufficient LSK cells for total RNA isolation and subsequent sequencing on HiSq2500. Two independent pairs of wild-type and mutant RNA samples (each of which contained LSK cells pooled from four embryos) were used for oligo-dT primed RNA Seq.
Project description:Loss of polycomb-group gene Ezh2 causes activation of fetal gene signature in adult mouse bone marrow (BM) hematopoietic stem and progenitor cells (HSPCs). Ezh2 directly represses fetal-specific let-7 target genes, including Lin28, thereby cooperates with let-7 microRNAs in silencing fetal gene signature in BM HSPCs. We purified Lineage-Sca-1+c-Kit+ (LSK) HSPCs from E14.5 FL and adult BM and subjected them to microarray analysis.

Project description:The aim of this study was to analyze the transcriptome of TER119+ fetal liver cells in the absence of the transcription factor KLF3 at murine embryonic day E14.5
Project description:The aim of this experiment was to investigate the role of KLF3 in regulating gene expression at different stages throughout the erythroid maturation process. Affymetrix microarrays were performed on fetal liver cells (both TER119- progenitor cells and TER119+ erythroblast cells) from E14.5 wildtype and Klf3 KO mice. Four wildtype TER119- replicates, four Klf3 KO TER119- replicates, four wildtype TER119+ replicates, three Klf3 KO TER119+ replicates. All are from E14.5 fetal liver.

Project description:Total RNA (15 ug) isolated from three each of wild type and Cited2-null E14.5 fetal livers using Qiagen RNeasy kit (Valencia, CA) was used to prepare biotinylated cRNA according to the protocol described in Affymetrix Expression Analysis Technical Manual. We hybridized a total of six GeneChip Mouse Genome 430A 2.0 arrays (Affymetrix), three for controls and three for experimental samples.
