TOP STORYNeuronal Network Dysfunction in a Model for Kleefstra Syndrome Mediated by Enhanced NMDAR Signaling To study the impact of decreased EHMT1 function in human cells, researchers generated excitatory cortical neurons from induced pluripotent stem cells derived from Kleefstra syndrome patients.

PUBLICATIONS(Ranked by impact factor of the journal)Genes Essential for Embryonic Stem Cells Are Associated with Neurodevelopmental Disorders Researchers performed a genome-wide screen for essential genes in mouse ESCs (mESCs) and compared it to screens in human cells. They found that essential genes were enriched for basic cellular functions, were highly expressed in mESCs, and tended to lack paralog genes. [Genome Res] Abstract HMGB2 Is a Negative Regulator of Telomerase Activity in Human Embryonic Stem and Progenitor Cells Stably transfected human ESCs (hESCs) capable of the short hairpin RNA-mediated knockdown of high-mobility group box (HMGB)1 and HMGB2, investigators provide evidence that deregulation of HMGB1 or HMGB2 expression in hESCs and their differentiated derivatives resulted in distinct modulation of telomere homeostasis. [FASEB J] Abstract Omitting an exogenous Wnt inhibitor, which is routinely added to maximize cardiac myocyte yield during differentiation of mouse and human ESCs, led to increased yield of spontaneously‐beating cardiomyocytes with action potential properties similar to those of native sinoatrial node pacemaker cells. [Stem Cells] Abstract Scientists differentiated 191 iPSC lines to generate iPSC-derived cardiovascular progenitor cells (CVPCs). They observed cellular heterogeneity across the iPSC-CVPC samples due to varying fractions of two cell types: cardiomyocytes and epicardium-derived cells. [Stem Cell Reports] Full Article | Graphical Abstract Researchers undertook a proteomic assessment of myeloid cells derived from induced pluripotent stem cells obtained from Noonan syndrome patients with PTPN11 mutations, either associated or not associated with increased incidence of juvenile myelomonocytic leukemia. [J Proteome Res] Abstract The authors investigated whether iPSCs could differentiate towards mesenchymal stromal cells when embedded into fibrin hydrogels to enable a one-step differentiation procedure within a scaffold. [Sci Rep] Full Article Seeding hESCs to Achieve Optimal Colony Clonality Investigators developed a quantitative framework for modeling the growth of human ESC (hESC) colonies from a given seeding density based on stochastic exponential growth. This allowed them to identify the timescales for colony merges and over which colony size no longer predicts the number of founding cells. [Sci Rep] Full Article Researchers inserted two important miRNAs, including miR‐22 and ‐126 in electrospun polycaprolactone (PCL) nanofibers and after scaffold characterization, osteoinductivity of fabricated nanofibers was investigated by evaluating of the osteogenic differentiation potential of iPSCs when grown on miRNAs‐incorporated PCL nanofibers and empty PCL. [J Biomed Mater Res A] Abstract A simple, rapid, efficient, and specialized culture system was successfully developed to induce human ESCs into dopaminergic neurons in vitro.

POLICY NEWSCalifornia Wildfires and Power Outages Cause Disruptions for Scientists Wildfires whipped up by hurricane-force winds have led to evacuations and precautionary power outages across California over the past few days. Major research institutions, including the University of California, Berkeley, endured their second blackout in a month. [Nature News] Editorial Increase in Academics Leaving the UK Since Brexit Vote After the 2016 Brexit referendum, in which voters decided to have the UK leave the European Union (EU), the number of academics from EU countries leaving the United Kingdom for other university jobs increased by almost half, according to Times Higher Education. [The Scientist] Editorial PhD-Turned-Policy Insider Takes Over World’s Largest Science Society in January 2020, the 46-year-old structural biologist Sudip Parikh will become the new CEO of AAAS (which publishes Science) as the 171-year-old association pursues its mission to advance science and serve society.
