Description
The sequence of gene regulatory events that drive neonatal germ cell development in the mammalian testis is not yet clear. We assessed changes in mRNA utilization in the neonatal testis at 1 and 4 dpp, times when the testis contains quiescent gonocytes (1 dpp) and proliferating spermatogonia (4 dpp). There are not thought to be major changes in the nature or number of somatic cells over that interval.

Description
Vascular smooth muscle cells (VSMCs) show pronounced heterogeneity across and within vascular beds, with direct implications for their function in injury response and atherosclerosis. Here we combine single-cell transcriptomics with lineage tracing to examine VSMC heterogeneity in healthy mouse vessels. The transcriptional profiles of single VSMCs consistently reflect their region-specific developmental history and show heterogeneous expression of vascular disease-associated genes involved in inflammation, adhesion and migration. We detect a rare population of VSMC-lineage cells that express the multipotent progenitor marker Sca1, progressively downregulate contractile VSMC genes and upregulate genes associated with VSMC response to inflammation and growth factors. We find that Sca1 upregulation is a hallmark of VSMCs undergoing phenotypic switching in vitro and in vivo, and reveal an equivalent population of Sca1-positive VSMC-lineage cells in atherosclerotic plaques. Together, our analyses identify disease-relevant transcriptional signatures in VSMC-lineage cells in healthy blood vessels, with implications for disease susceptibility, diagnosis and prevention. Overall design: This entry contains data from the following analyses: (1) Bulk RNA-seq of mouse VSMCs isolated from aortic arch (AA) and descending thoracic aorta (DT) regions in triplicates. (2) Pooled RNA-seq of mouse Sca1- VSMCs and Sca1- or Sca1+ adventitial cells in triplicates. (3) Single-cell RNA-seq of VSMCs from the AA and DT regions (143 cells). (4) VSMC lineage label positive and negative cells isolated from the medial layer of mouse aorta, which expressed or did not express the Sca1 protein (155 cells). (5) 10X single-cell RNA-seq analysis of: lineage positive plaque cells isolated from mice following 14 or 18 weeks of high fat diet feeding, cells isolated from the whole aorta and lineage positive VSMCs from the medial layer.

Description
Heterogeneity in pluripotent cells marks a metastable state where cells may drift between native and lineage-primed populations. While the role for these heterogeneities are unclear, they may reflect the dynamic equilibriums of signaling networks and have a direct effect on differentiation potentialities. Here, we report the role of the cell cycle in establishing heterogeneity of human pluripotent stem cells. By utilizing the FUCCI cell cycle indicator system coupled to fluorescent activated cell sorting (FACS), we have uncovered that the cell cycle drives heterogeneity at the epigenetic, transcriptional and post-transcriptional levels. Our data show widespread dynamics in 5-hydroxymethylcytosine (5hmC) during the cell cycle. Furthermore, transcript profiling by RNA-sequencing identified >500 genes that were cell cycle-regulated, of which the largest cohort of genes were transcriptional regulators. In sum, we demonstrate the role of the cell cycle in coordinating cellular transitions between metastable states in pluripotent stem cells. Overall design: mRNA sequencing of the cell cycle phases; early & late G1, S and G2/S from human ES cells in triplicate.

Description
Microglia are yolk sac-derived macrophages residing in the parenchyma of brain and spinal cord, where they interact with neurons and other glial cells by constantly probing their surroundings with dynamic extensions. After different conditioning paradigms and bone marrow (BM) or hematopoietic stem cell (HSC) transplantation, graft-derived cells seed the brain and persistently contribute to the parenchymal brain macrophage compartment. Here we establish that graft-derived macrophages acquire, over time, microglia characteristics, including ramified morphology, longevity, radio-resistance and clonal expansion. However, even after prolonged CNS residence, transcriptomes and chromatin accessibility landscapes of engrafted, BM-derived macrophages remain distinct from yolk sac-derived host microglia. Furthermore, engrafted BM-derived cells display discrete responses to peripheral endotoxin challenge, as compared to host microglia. In human HSC transplant recipients, engrafted cells also remain distinct from host microglia, extending our finding to clinical settings. Collectively, our data emphasize the molecular and functional heterogeneity of parenchymal brain macrophages and highlight potential clinical implications for HSC gene therapies aimed to ameliorate lysosomal storage disorders, microgliopathies or general monogenic immuno-deficiencies. Overall design: overall there are 28 samples, from total of 2 experiments. in each experiment there were at least 3 biological repeats (3 individual mice). Sorting of the CD45.1 and CD45.2 populations were performed from the same animal. Animals were either injected with LPS (2.5 mg/kg) or untreated.

Description
Peripheral blood neutrophils from periodontitis patients exhibit a hyper-reactive and hyper-active phenotype (collectively termed hyper-responsivity) in terms of production of reactive oxygen species (ROS) however the molecular basis for this observation is yet to be determined. Our objectives were to identify genes differentially expressed in hyper-responsive peripheral blood neutrophils from chronic periodontitis patients relative to periodontally healthy controls and use this data to identify potential contributory pathways to the hyper-responsive neutrophil phenotype.

Description
Purpose: The aim of this study is to determine the relative expresson levels of mRNA transcripts in wild type platelets Methods: Total RNA was extracted and purified from purified platelets from BALB/c male mice (3 independent samples). Platelet purification was performed as described in Josefsson EC et al, Journal of Experimental Medicine (2011) 208:2017-31. Total RNA (100 ng) was used to generate sequencing libraries for whole transcriptome analysis following Illumina’s TruSeq RNA v2 sample preparation protocol. Completed libraries were sequenced on HiSeq 2000 with TruSeq SBS Kit v3- HS reagents (Illumina) as 100 bp paired-end reads at the Australian Genome Research Facility (AGRF), Melbourne. Reads were aligned to the mouse reference genome mm10 and counts for known genes were obtained using the Rsubread package (version 1.18.0) (Liao et al. 2013; Liao et al. 2014). Overall design: Total RNA was extracted and purified from purified platelets from BALB/c male mice (3 independent samples per population).
