Chronological expression data from mouse skeletal muscle stem cells

ABSTRACT: Satellite cells are the primary source of stem cells for skeletal muscle growth and regeneration. Since adult stem cell maintenance involves a fine balance between intrinsic and extrinsic mechanisms, we performed genome-wide chronological expression profiling to identify the transcriptomic changes involved in acquisition of muscle stem cell characteristics. Muscle samples were isolated from the trunk during development, postnatally and in adult and aged Pax3GFP/+ mice. After digestion, GFP cells were purified via FACS and process for RNA extraction and hybridization on Affymetrix microarrays (Affymetrix Mouse Genome 430 2.0 Arrays). The different ages selected for sample isolation were E11.5-E12.5-E13.5-E14.5-E15.5-E17.5-P1-P12-1MO-2MO-18MO (E, Embryonic days; P, Postnatal days; MO, age in months), covering embryonic and fetal progenitors and proliferant, quiescent satellite cells. The eleven stages were done in triplicate for E11.5-E12.5-E14.5-E15.5-1MO-2MO-18MO, twice for E13.5, 4 times for P1-P12 and 5 times for E17.5, so 36 samples included in the microarray.

Early postnatal expression data from mouse skeletal muscle stem cells

Project description:Satellite cells are the primary source of stem cells for skeletal muscle growth and regeneration. Since adult stem cell maintenance involves a fine balance between intrinsic and extrinsic mechanisms, we performed genome-wide chronological expression profiling to identify the transcriptomic changes involved during early postnatal growth till acquisition of satellite cell quiescence. Muscle samples were isolated from the trunk of Pax3GFP/+ mice. After digestion, GFP cells were purified via FACS and process for RNA extraction and hybridization on Affymetrix microarrays (Affymetrix Mouse Genome 430 2.0 Arrays). The different ages selected for sample isolation were P1-P12-P28 (P, postnatal days), covering proliferant and quiescent satellite cells. The three stages were done in triplicate for P28 and 4 times for P1-P12, so 11 samples included in the microarray.

Multi-stage analysis of gene expression in C57/B6 mouse liver development

Project description:The liver performs a number of essential functions for life. The development of such a complex organ relies on finely regulated gene expression profiles which change over time in the development and determine the phenotype and function of the liver. We used high-density oligonucleotide microarrays to study the gene expression and transcription regulation at 14 time points across the C57/B6 mouse liver development, which include E11.5 (embryonic day 11.5), E12.5, E13.5, E14.5, E15.5, E16.5, E17.5, E18.5, Day0 (the day of birth), Day3, Day7, Day14, Day21, and normal adult liver. With these data, we made a comprehensive analysis on gene expression patterns, functional preferences and transcriptional regulations during the liver development. Keywords: time course

Single cell RNA-seq of the developing mouse hypothalamus

Project description:Neurons in the hypothalamic arcuate nucleus (ARC) are fundamental regulators of energy homeostasis, growth and reproduction. Spatially overlapping subpopulations of ARC neurons produce specific neuropeptides including melanocortins, opioids, neuropeptide Y, growth hormone releasing hormone and kisspeptin. However, the developmental pathways controlling ARC neuron specification, differentiation and maturation remain poorly understood relative to more structurally ordered brain regions. Here, we analyzed the transcriptomes of individual mouse ARC neurons sorted for expression of a Proopiomelanocortin-Td-dsRed transgene at four embryonic (E11.5, E13.5, E15.5 and E17.5) and two postnatal (P5 and P12) ages. There was an unanticipated complexity of neurochemical subpopulations in the developing ARC characterized by low, medium or high levels of Pomc transcripts and distinct temporal patterns of transcription factor expression. Moreover, sizeable fractions of Pomc-positive neural progenitors differentiated into non-POMC neurons by P12. We conclude that ARC neuronal development is highly dynamic with plasticity that may be susceptible to environmental programming.

Transcripts with H3K36me3 modification at differente stages of pancreas organogensis [CUT&Tag]

Project description:To find the genes with H3K36me3 modificaiton at different stages of pancreas development, we isolated the pancreatic epithelial cells from E11.5, E13.5 and E15.5 fetal pancreas. Considering the low expression of H3K36me3 at E11.5, E11.5 samples worked as a "negantive" control. By compared with the peaks of E11.5, we was able to find genes under direct regulation of H3K36me3 at E13.5 and E15.5.

Single cell RNA-seq developmental series in mouse hypothalamus in wild-type and Eed-cKO

Project description:Neuronal sub-type diversity in the hypothalamus is staggeringly immense. To investigate the role of epigenetic regulation in hypothalamic development in the generation of this cellular diversity; a floxed Eed allele was crossed to the early, pan-CNS Cre deleter Sox1-Cre, resulting in loss of H3K27me3 in the entire Mus musculus CNS by E11.5. E12.5, E13.5, E15.5, and E16.5 embryonic mouse hypothalamic cells were dissected and analysed by single cell RNA sequencing, on the Illimina/BioRad platform.

Expression profiling of FACS-purified fetal germ cells

Project description:We used microarrays to profile global gene expression changes of Pou5f1-GFP-positive germ cells between E11.5 to E15.5. Germ cells were FACS-purified from gonadal single cell suspension based on Pou5f1-GFP expression. Three timepoints were included in this study: E11.5 (male/female), E13.5 (male) and E15.5 (male). For each timepoint, three biological replicates were analyzed. The Pou5f1-GFP-negative (non-germ cell) fraction of E13.5 (male) gonads was also included as a control.
