Project description:Mocetinostat (MGCD) which is a kind of histone deacetylase inhibitors (HDACi) promotes human embryonic stem cells (hESCs) differentiation towards neural progenitor cells (NPCs). Application of HDAC inhibitors (HDACi) increased the expression of neuroectodermal markers once neural differentiation was initiated, thereby leading to more NPC generation. We used microarrays to detail the global gene expression during NPC differentiaton upon MGCD treatment and identified the transcript changes effected by MGCD during this process. Undifferentiated H9 hESCs (D0), as well as H9 cells with or without MGCD treatment on day 3 (D3C and D3M) and on day 7(D7C and D7M) of NPC generation were collected for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Neural progenitor cells (NPCs) can be induced from somatic cells by defined factors. Here we report that NPCs can be generated from mouse embryonic fibroblasts by a chemical cocktail, namely VCR (V, VPA, an inhibitor of HDACs; C, CHIR99021, an inhibitor of GSK-3 kinases and R, Repsox, an inhibitor of TGF-β pathways), under a physiological hypoxic condition. These chemical-induced NPCs (ciNPCs) resemble mouse brain-derived NPCs regarding their proliferative and self-renewing abilities, gene expression profiles, and multipotency for different neuroectodermal lineages in vitro and in vivo. Further experiments reveal that alternative cocktails with inhibitors of histone deacetylation, glycogen synthase kinase, and TGF-β pathways show similar efficacies for ciNPC induction. Moreover, ciNPCs can also be induced from mouse tail-tip fibroblasts and human urinary cells with the same chemical cocktail VCR. Thus our study demonstrates that lineage-specific conversion of somatic cells to NPCs could be achieved by chemical cocktails without introducing exogenous factors. To access the exact identity of ciNPCs, we extracted mRNA from mouse brain-derived NPCs (as control NPCs), MEFs, ciNPCs at passage 5 and passage 13 and compared the global gene expression patterns of these cells by microarray analysis.

Project description:Neural stem cells (NSCs) and progenitor cells (NPCs) are increasingly appreciated to hold great promise for regenerative medicine to treat CNS injuries and neurodegenerative diseases. However, evidence for effective stimulation of neuronal production from endogenous or transplanted NPCs for cell replacement with small molecules remains limited. To identify novel chemical entities/targets for neurogenesis, we had established a NPC phenotypic screen assay and validated it using known small-molecule neurogenesis inducers. Through screening small molecule libraries with annotated targets, we identified BET bromodomain inhibition as a novel mechanism for enhancing neurogenesis. BET bromodomain proteins, Brd2, Brd3, and Brd4 were found to be downregulated in NPCs upon differentiation, while their levels remain unaltered in proliferating NPCs. Consistent with the pharmacological study using bromodomain selective inhibitor (+)-JQ-1, knockdown of each BET protein resulted in an increase in the number of neurons with simultaneous reduction in both astrocytes and oligodendrocytes. Gene expression profiling analysis demonstrated that BET bromodomain inhibition induced a broad but specific transcription program enhancing directed differentiation of NPCs into neurons while suppressing cell cycle progression and gliogenesis. Together, these results highlight a crucial role of BET proteins as promising epigenetic regulators in NPC development and suggest a therapeutic potential of BET inhibitors in treating CNS injury and neurodegenerative diseases. NPCs were treated with (+)-JQ-1 or inactive enantiomer (-)-JQ-1 at 0.2 μM or 0.5 μM for 12 and 24 hrs in differentiation medium. The experiments were carried out in 3 independent preparations of NPCs (triplicates)

Project description:Exosome, a kind of extracellular vesicles, has been introduced as a vehicle for horizontal transferring of genetic material. We induced autologous exosome containing a cocktail of reprogramming factors (‘reprosome’) to convert fibroblasts into neural progenitor cells (NPC). The fibroblasts were sonicated and subsequently cultured in NSC media for 1 day to induce release of reprosomes composed of reprogramming factors associated to chromatin remodeling and neural lineage-specific factors. After treated with reprosomes, fibroblasts were converted into NPCs (rNPC) with great efficiency via activation of chromatin remodeling, as fast as it required only five days for formation of 1,500 spheroids showing NPC-like phenotype. The rNPCs maintained self-renewal and proliferative properties for several weeks and successfully differentiated into neuron, astrocyte, and oligodendrocyte, in vitro and in vivo. Reprosome-mediated cellular reprogramming is simple, safe, and efficient, thus providing a new paradigm for clinical application that requires autologous stem cells.

Project description:The developing mammalian brain generates a variety of Neural Progenitor Cells (NPCs). Primary NPCs throughout the neuraxis are derived from the ventricular zone. Intermediate progenitor cells (IPCs) are produced uniquely in the telencephalon and contribute extensively to the neurons that comprise the cerebral cortex and basal ganglia. It is known that the fate of the diverse NPC populations is determined by the interplay of transcription factors and regulation by regional humoral cues. However, despite our recent appreciation that nutrient-regulated intracellular metabolic milieu (pO2, energy, and redox state) significantly influence cell fate, an unexplored area is whether NPCs have intrinsic metabolic identity, and if so, the mechanism by which molecular metabolism contributes to brain development.Little is known however, if intrinsic differences in cellular metabolism of regional NPCs make certain NPCs susceptible while others resistant to genetic and environmental insults. We conjectured that regional (fore-and hindbrain) NPCs are metabolically distinct.
