Description
Analysis of transcriptional differences between control and RA-treated cells during cardiac differentiation. The hypothesis tested in these samples is that addition of RA during differentiation towards atrial-like cardiomyocytes while control cells treated with DMSO result in ventricular-like cardiomyocytes. Overall design: NKX2.5 (eGFP/w)-hESCs were differentiated to cardiomyocytes with spin EB protocol, with the addition of RA or DMSO. Cells were sorted at day-31 based on GFP resulting in CTplus, CTminus, RAplus or RAminus goups. RNA was isolated from each of these fractions for sequencing.

Description
Autophagy is critical for protecting HSCs from metabolic stress. Here, we used a genetic approach to inactivate autophagy in adult HSCs by deleting the Atg12 gene. We show that loss of autophagy causes accumulation of mitochondria and an oxidative phosphorylation (OXPHOS)-activated metabolic state, which drives accelerated myeloid differentiation likely through epigenetic deregulations rather than transcriptional changes, and impairs HSC self-renewal activity and regenerative potential.

Description
Multipotent stromal cells (MSC) and their osteoblastic lineage cell (OBC) derivatives are part of the bone marrow (BM) niche and contribute to hematopoietic stem cell (HSC) maintenance. During myeloproliferative neoplasm (MPN) development, MSCs are stimulated to overproduce functtionally altered OBCs, which accumulate in the BM cavity as myelofibrotic cells. These MPN-expanded OBCs, in turn, impair the maintenance of normal HSCs but not of leukemic stem cells.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Loss of Rb family in HSCs results in a severe phenotype, such as enhanced proliferation and increase in stem cell number. In addition, HSCs were higly mobilized but failed to transplant. Rb family deficient mice rapidly exhibit a myeloproliferative disease with eosinophilic characteristics. Meanwhile, the lymphoid compartment was severely decreased, due to high apoptotic activity in this lineage.

Description
Epigenetic regulation serves as the basis for stem cell differentiation into distinct cell types, but it is unclear how global epigenetic changes are regulated during this process. Here, we tested the hypothesis that global chromatin organization affects the lineage potential of stem cells and that manipulation of chromatin dynamics influences stem cell function. Using nuclease sensitivity assays, we found a progressive decrease in chromatin digestion between pluripotent embryonic stem cells (ESCs), multipotent hematopoietic stem and progenitor cells (HSPCs), and mature hematopoietic cells. Quantification of chromatin composition by high-resolution microscopy revealed that ESCs contain significantly more euchromatin than HSPCs, with a further reduction in euchromatin as HSPCs transition into mature cells. Increased cellular maturation also led to heterochromatin localization to the nuclear periphery. Functionally, prevention of heterochromatin formation by inhibition of the histone methyltransferase G9a resulted in delayed hematopoietic stem cell (HSC) differentiation. Our results demonstrate significant global rearrangements of chromatin structure during embryonic and adult stem cell differentiation, and that heterochromatin formation by H3K9 methylation is an important regulator of HSC differentiation. Overall design: Examination of gene expression profile of in vitro cultured mouse HSC with the G9a inhibitor UNC0638
