(Submitter supplied) The study is designed to identify transcriptional differences of CD45-Ter119-Cxcl12-DsRed+ stromal cells at different develomental stages. 50,000 CD45-Ter119-Cxcl12-DsRed+ stromal cells from freshly prepared livers of E15.5, P5 and P10 Cxcl12DsRed/+ mice were sorted into Trizol by flow cytometry. Total RNA was isolated and amplified with the WT-Ovation Pico RNA Amplification system (Nugen) as the manufacturer’s instructions. more...

(Submitter supplied) It has been shown previously that endothelial cells and LepR+ stromal cells are the main sources of SCF in vivo in the mouse bone marrow. We tested whether SCF from endothelial cells and/or LepR+ stromal cells is important for the maintenance of hematopoietic progenitors and erythroid progenitors in mouse bone marrow by conditional deletion of Scf from these two cell types. We discovered that Scf deletion from LepR+ stromal cells, but not endothelial cells, reduced the numbers of hematopoietic progenitors and erythroid progenitors in mice. more...

(Submitter supplied) 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. To characterize the novel Scf-GFP+ cells from the bone marrow, we performed microarray analysis on these cells.

(Submitter supplied) Adult hematopoietic stem cells (HSCs) reside primarily in bone marrow. However, hematopoietic stresses such as myelofibrosis, anemia, pregnancy, infection or myeloablation can mobilize HSCs to the spleen and induce extramedullary hematopoiesis (EMH). While the bone marrow HSC niche has been studied intensively, the EMH niche has received little attention. Here, we systematically assessed the physiological sources of the key niche factors, SCF and CXCL12, in the mouse spleen after EMH induction by cyclophosphamide plus granulocyte colony-stimulating factor, blood loss, or pregnancy. more...

(Submitter supplied) Fate decisions of haematopoietic stem cells (HSCs) to self-renew or differentiate in response to various demands are finely tuned by specialized microenvironments called “niches” in the bone marrow. Recent studies suggest that arterioles and sinusoids accompanied with distinct stromal cells marked by nerve/glial antigen 2 (NG2) and leptin receptor (LepR), compose distinct niches regulating quiescence and proliferation of HSCs, respectively. more...

(Submitter supplied) In this study, we demonstrated that deletion of the activating transcription factor 4 (ATF4) resulted in severely impaired HSC expansion in the fetal liver at E12.5 and E15.5. In contrast, generation of the first HSC population in the aorta-gonad-mesonephros region at E11.5 was not significantly affected. Furthermore, the HSC-supporting ability of both endothelial and stromal cells in fetal liver was significantly compromised in the absence of ATF4. more...

(Submitter supplied) The molecular determinants of a healthy human liver cell phenotype remain largely uncharacterized. In addition, the gene expression changes associated with activation of primary human hepatic stellate cells, a key event during fibrogenesis, remain poorly characterized. Here, we provide the transriptomic profile underpinning the healthy phenotype of human hepatocytes, liver sinusoidal endothelial cells (LSECs) and quiescent hepatic stellate cells (qHSCs) as well as activated HSCs (aHSCs) We assess the transcriptome for purified, non-cultured human hepatocytes, liver sinusoidal cells (LSECs) and quiescent hepatic stellate cells (qHSCs) as well as culture-activated HSCs (aHSCs).

(Submitter supplied) The human liver contains multiple cell types whose epigenetic patterns are undetermined. We examined the promoter methylome of purified and uncultured hepatic stellate cells (HSCs), hepatocytes (HEPs) and liver sinusoidal endothelial cells (LSECs), by methylated DNA immunoprecipitation (MeDIP) and array hybridization. Uncultured HSCs, LSECs and Heps show ~7000-8000 methylated promoters, with 60-70% similarity between all cell types. more...

(Submitter supplied) There are a few markers for embryonic hepatic stellate cells in mouse embryonic livers To identify genes expressed in embryonic hepatic stellate cells, we separated ALCAM+, ALCAM+ PDPN+, and ALCAM+ PDPN- cells from E12.5 mouse livers and analyzed these cells by microarray analysis. After finding expression of Itga8 in ALCAM+ PDPN- cells, we further separated ALCAM+ ITGA8- and ALCAM+ ITGA8+ cells and analyzed by microarray.

(Submitter supplied) Hepatic stellate cell autophagy inhibits extracellular vesicle release to attenuate liver fibrosis. Primary human hepatic stellate cells were treated with PDGF or PDGF + SHP2 inhibitor. RNA was purified and submitted for sequencing to Mayo Clinic Genomics Core. After applying the filters FDR>0.05, Log2(FC)>1 and RPKM>15, we ended up with nearly 300 genes differentially regulated between the two conditions. more...

In the mouse liver, hepatocytes in the midlobular zone that are positive for cyclin D1 (CCND1) repopulate the parenchyma at a constant rate to preserve liver mass.

(Submitter supplied) We profile the transcriptomes of over 100,000 human single cells, yielding molecular definitions for non-parenchymal cell types present in healthy and cirrhotic human liver. We uncover a novel scar-associated TREM2+CD9+ macrophage subpopulation, which expands in liver fibrosis, differentiates from circulating monocytes, has a corollary population in mouse liver fibrosis and is pro-fibrogenic. We also define novel ACKR1+ and PLVAP+ endothelial cells which expand in cirrhosis, are topographically scar-restricted and enhance leucocyte transmigration. more...

(Submitter supplied) Adult-derived human liver stem/progenitor cells (ADHLSC) are obtained after primary culture of the liver parenchymal fraction. The cells are of fibroblastic morphology and exhibit a hepato-mesenchymal phenotype. Hepatic stellate cells (HSC) derived from the liver non-parenchymal fraction present a comparable morphology as ADHLSC. Because both ADHLSC and HSC are described as liver stem/progenitor cells, we strived to extensively compare both cell populations at different levels and to propose tools demonstrating their singularity.
