Epigenetic Priming by Dppa2 and 4 in Pluripotency Facilitates Multi-Lineage Commitment

Differentiation assays revealed that developmental pluripotency associated 2 and 4 (Dppa2/4) double knockout mouse ESCs failed to exit pluripotency and differentiate efficiently.

BRPF3-HUWE1-Mediated Regulation of MYST2 Is Required for Differentiation and Cell-Cycle Progression in Embryonic Stem Cells

Researchers provided novel insights into understanding the functions of Brpf3 in proper differentiation as well as cell-cycle progression of ESCs via regulation of Myst2 stability by obstructing Huwe1-mediated ubiquitination.

In Vitro Differentiated Human Stem Cell-Derived Neurons Reproduce Synaptic Synchronicity Arising during Neurodevelopment

Scientists generated human iPSC-derived neurons exhibiting spontaneous oscillatory activity after cultivation of up to six months, which resembled early oscillations observed in rodent neurons. This behavior was found in neurons generated using a more “native” embryoid body protocol, in contrast to a “fast” protocol based on NGN2 overexpression.

The Chromatin Regulator ZMYM2 Restricts Human Pluripotent Stem Cell Growth and is Essential for Teratoma Formation

The authors examined the effect of mutations in 703 genes from nearly 70 chromatin-modifying complexes on human ESC growth. While the vast majority of chromatin-associated complexes were essential for ESC growth, the only complexes that conferred growth advantage upon mutation of their members, were the repressive complexes LSD-CoREST and BHC.

Cortical Neurons Derived from Human Pluripotent Stem Cells Lacking FMRP Display Altered Spontaneous Firing Patterns

Electrophysiological whole-cell voltage- and current-clamp recordings were performed on two control and three fragile X syndrome patient lines of human cortical neurons derived from iPSCs.

Novel Venom-Based Peptides (P13 and Its Derivative—M6) to Maintain Self-Renewal of Human Embryonic Stem Cells by Activating FGF and TGFβ Signaling Pathways

Investigators provided the first research finding on a venom-based peptide that works on the FGF and TGF-β signaling pathways to maintain the self-renewal of human ESCs.

Signaling Inhibitors Accelerate the Conversion of Mouse iPS Cells into Cancer Stem Cells in the Tumor Microenvironment

Inhibition of Erk1/2, tyrosine kinase, and/or GSK-3β was implied to be involved in the enhancement of the PI3K-AKT signaling pathway in the undifferentiated cells, resulting in the sustained stemness, and subsequent conversion of mouse iPSCs into cancer stem cells in the tumor microenvironment.

Derivation of Oocyte-Like Cells from Putative Embryonic Stem Cells and Parthenogenetically Activated into Blastocysts in Goat

Scientists demonstrated that goat putative ESCs were successfully in vitro differentiated into primordial germ cells and oocyte-like cells using bone morphogenetic protein-4 and trans-retinoic acid.

AAV-Mediated FOXG1 Gene Editing in Human Rett Primary Cells

Investigators demonstrated that an adeno-associated viruses-coupled CRISPR/Cas9 system was able to target and correct Forkhead Box G1 (FOXG1) variants in patient-derived fibroblasts, iPSCs and iPSC-derived neurons.

Abstract

A Simple, Quick, and Efficient CRISPR/Cas9 Genome Editing Method for Human Induced Pluripotent Stem Cells

The authors report an electroporation-mediated plasmid CRISPR/Cas9 delivery approach for genome editing in iPSCs. With this approach, an edited iPSC cell line could be obtained within two weeks.

Abstract

A lncRNA-miRNA-mRNA Network for Human Primed, Naive and Extended Pluripotent Stem Cells

Researchers successfully converted three in-house-derived primed human PSC lines (H10, H24, and iPS) to a naive state and an expanded PSC (EPS) state. Primed, naive and EPS cells displayed state-specific morphologies and expressed pluripotent markers.
