Description
Human naïve pluripotent stem cells (PSC) share features with pre-implantation epiblast. They thus provide an unmatched opportunity for characterising the developmental programme of pluripotency in Homo sapiens. Here we confirm that naïve PSC do not respond directly to germ layer induction, but must first acquire competence. Capacitation for multi-lineage differentiation occurs without exogenous growth factor stimulation and is facilitated by inhibition of Wnt signalling. Whole transcriptome profiling during this formative transition highlights dynamic changes in gene expression, affecting many cellular properties, including metabolism and epithelialisation. Notably, naïve pluripotency factors are exchanged for post-implantation factors, but competent cells remain devoid of lineage primed transcription. The gradual pace of transition for human naïve PSC is consistent with the timespan of primate development from blastocyst to gastrulation. Transcriptome trajectory during in vitro capacitation of human naïve cells tracks the progression of epiblast during embryogenesis in Macaca fascicularis, but shows greater divergence from mouse development. Thus the formative transition of naïve PSC in a simple culture system may recapitulate essential and specific features of pluripotency dynamics during an inaccessible period of human embryogenesis. Overall design: 2 lines of human naïve pluripotent stem cells (embryo-derived HNES1 and chemically reset cR-H9-EOS) were cultured in N2B27 and 2uM XAV939 for 10 days. After that the cells were split into two conditions: N2B27 + 2uM XAV939 + 3ng/ml Activin A + 10ng/ml FGF2 (XAF), or E8 medium, for extended maintenance. The experiment was performed in biological triplicates for each cell line. RNAseq was performed with the cells on day 0, 1, 2, 3, 7, 10, when the cells were cultured in XAV939; and one time point after transfer to maintenance conditions, at not less than 22 days of culture from the start of the experiment. Conventional hES cell line H9-EOS, which was a parental line for the chemically reset cR-H9-EOS was used as a control (in biological triplicate).

Description
We tested how complete or partial loss of endophilin A1, A2 and A3 affects gene expression in mouse hippocampus. Total loss of endophilin (triple knock-outs, TKO) was assessed in newborn mice, since the TKO mice only survive only several hours after birth. Partial loss of endophilin (endoA1,A2 double knock-out, DKO) was assessed between Overall design: 2-3 weeks of age (p13-21).

Description
Bone marrow stromal cells (BMSCs) were isolated from the femora and tibiae of irtTA-GBD*-TAg transgenic mice. Using cellular cloning we established skeletal progenitors with distinct differentiation properties and analysed their transcriptome. Unipotent osteogenic and adipogenic cells expressed specific transcriptional programs whereas bipotent clones combined expression of those genes and did not show a unique signature. Overall design: Expression profiling (RNA-seq) of two independent clones from different mice representing skeletal progenitors with the following characteristics: tripotent clones (Osteogenic, Adipogenic, Chondrogenic = OAC1 and OAC2); bipotent clones (Osteogenic, Adipogenic = OA1 and OA2); unipotent clones (Osteogenic = O1 and O2; Adipogenic = A1 and A2). Further, we prepared and sequenced pools of several other clones from these two mice, with the following properties: tripotent clones (Osteogenic, Adipogenic, Chondrogenic = OAC3); bipotent clones (Osteogenic, Adipogenic = OA3; Osteogenic, Chondrogenic = OC3; Adipogenic, Chondrogenic = AC3); unipotent clones (Osteogenic = O3; Adipogenic = A3).

Human embryonic stem cells were differentiated into peripheral sensory neurons via the intermediate generation of neural crest like cell (NCC). Using various markers we identified these cells as LTMR. We then analyzed there complete transcriptional profile in comparison to the intermediate neural crest like cells. Overall design: mRNA expression data of human ESC-derived sensory neuron clusters (10-20 cells) and human ESC-derived neural crest like cells (~100 cells) was generated by illumina deep sequencing

Description
Calcium/calmodulin-dependent protein kinase II (CaMKII) was suggested to mediate ischemic myocardial injury and adverse cardiac remodeling. However, the specific functions of the CaMKII isoforms and splice variants in ischemia/reperfusion (I/R) injury have not been investigated yet. Thus, we studied the roles of the CaMKII isoforms and splice variants in I/R by the use of various CaMKII mutant mice. CaMKIIC was up-regulated already one day after I/R injury but surprisingly, acute I/R injury was neither affected in CaMKII-deficient mice, CaMKII-deficient mice in which the splice variants CaMKIIB and C were re-expressed nor in conditional CaMKII/ double-knockout mice (DKO). In contrast, 5 weeks after I/R, DKO mice were protected against extensive scar formation and cardiac dysfunction. Leukocyte infiltration was not altered one day but five days after I/R, explaining the late effects of CaMKII deletion on post-I/R remodeling. Other than reported before, we demonstrate that CaMKII is not critically involved in the immediate mechanisms that regulate acute I/R injury but in the process of post-infarct remodeling.

Description
As recently reported by our group, we performed miRNA and gene expression profiling of CD34+ hematopoietic stem/progenitor cells (HSPCs) isolated from 42 PMF patient samples compared with 31 healthy controls. Integrative analysis of these profiles by means of Ingenuity Pathway Analysis (IPA) allowed the identification of several aberrantly regulated miRNA-mRNA target pairs organized in interaction networks. In particular, our results highlighted the up-regulation of miR-494-3p in CD34+ cells from PMF patients (Norfo R et al, Blood, 2014). Interestingly, among the most upregulated miRNAs, miR-494-3p emerges as being associated to the highest number of downregulated target mRNAs. In order to understand the biological role of miR-494-3p during the hematopoietic commitment and differentiation, we overexpressed this miRNA in cord blood (CB) derived-CD34+ cells. Cells were electroporated with either miR-494-3p miRNA mimic (mimic miR-494) or a negative control mimic (mimic Neg CTR). qRT-PCR confirmed miR-494-3p overexpression 24h and 4 days after transfection (RQ SEM, 512.60 137.37, p<.01, and 20.63 3.03, p<.01, respectively).
