The HSC niche factor SCF is required for HSC maintenance. Using an Scf-GFP knockin mouse, we have identified a perivascular cell type in the bone marrow expressing high level of Scf.
Endothelial and perivascular cells maintain haematopoietic stem cells.

View SamplesThe transition in developmental control from maternal to zygotic gene products marks a critical step in early embryogenesis. Here, we use GRO-seq analysis to map the genome-wide RNA polymerase distribution during the Drosophila maternal to zygotic transition. This analysis unambiguously identifies the zygotic transcriptome, and provides insight into its mechanisms of regulation. Overall design: Two replicates of GRO-seq at each time point.
Extensive polymerase pausing during Drosophila axis patterning enables high-level and pliable transcription.

View SamplesChoroid plexuses (CP) develop early during development. They form a barrier between the blood and the cerebrospinal fluid, and fulfill important protective and nutritive functions. We used Affymetrix microarrays to assess whether CP of the lateral ventricles (LVCP) have similar functions in developing and adult brain. We identified distinct families of protective and transport genes and found that most of these genes were already well expressed during development.

View SamplesMaternal obesity is linked with increased adverse outcomes for mother and fetus. However, the metabolic impact of excessive fat accumulation within the altered hormonal context of pregnancy is not well understood. We used a murine model of obesity, the high fat diet-fed C57BL/6J mouse to determine adipose tissue-mediated molecular mechanisms driving metabolic dysfunction throughout pregnancy. Remarkably, obese mice exhibited a normalization of visceral fat accumulation at late-stage pregnancy (-53%, P<0.001 E18.5) to achieve levels comparable in mass (per gram of body weight) to that of non pregnant, control diet fed mice. Moreover, whilst obese pregnant mice showed a marked glucose intolerance and apparent insulin resistance at mid-stage pregnancy (E14.5), glucose homeostasis converged with that of lean pregnant mice at late-stage pregnancy, suggesting an unexpected amelioration of the worsening metabolic dysfunction in obese pregnant mice.
Pregnancy in obese mice protects selectively against visceral adiposity and is associated with increased adipocyte estrogen signalling.

View SamplesPluripotent cell identity comprises a spectrum of cell states including naive and primed states, which are typified by mouse embryonic stem cells (ESCs) and epiblast-derived stem cells (EpiSCs), respectively. Here we define a pluripotent cell fate (PCF) gene signature based on RNA-seq analysis associated with naive and primed pluripotency acquisition, and identify Zfp281 as a key transcriptional regulator for primed pluripotency and also as a barrier to achieve the naive pluripotency of both mouse and human ESCs. Overall design: RNA sequencing analysis was performed in WT and Zfp281 null mouse embryonic stem cells under different pluripotent culture conditions. RNA-seq Experiments were carry out in two biological replciates. Genome binding/occupancy profiling of Zfp281 was performed in mouse embryonic stem cells by ChIP sequencing.

View SamplesOverexpression of glomerular JAK2 mRNA specifically in glomerular podocytes of 129S6 mice led to significant increases in albuminuria, mesangial expansion, glomerulosclerosis, glomerular fibronectin accumulation, and glomerular basement membrane thickening as well as a significant reduction in podocyte density in diabetic mice.
