TOP STORYControlled Modeling of Human Epiblast and Amnion Development Using Stem Cells Researchers report that human PSCs in a microfluidic device recapitulated, in a highly controllable and scalable fashion, landmarks of the development of the epiblast and amniotic ectoderm parts of the conceptus, including lumenogenesis of the epiblast and the resultant pro-amniotic cavity, formation of a bipolar embryonic sac, and specification of primordial germ cells and primitive streak cells.

PUBLICATIONS(Ranked by impact factor of the journal)Dynamic Reversal of Random X-Chromosome Inactivation during iPSC Reprogramming Scientists showed that X-Chromosome inactivation reactivation was hierarchical, with subsets of genes reactivating early, late, and very late during reprogramming. Early genes were activated before the onset of late pluripotency genes activation. [Genome Res] Abstract | Full Article | Press Release Investigators showed that DNA hypomethylation, as observed in 2i, was a contributor to genome-wide gain of H3 lysine 27 trimethylation (H3K27me3), while active demethylation by JMJD3/UTX counteracted further accumulation of H3K27me3. [Cell Rep] Full Article | Graphical Abstract Inactivation of NEUROD1 in human ESCs severely impaired their differentiation from pancreatic progenitors into insulin expressing cells; however survival or proliferation was not affected at the time points analyzed. [Diabetes] Abstract iPSC lines derived from a donor were differentiated into CD14+ macrophages and tested for their capacity to present antigen to T cell receptors derived from islet-infiltrating CD4+ T cells from the same donor. [Diabetologia] Full Article Using Pompe disease (Pom)-iPSC-derived neurons as an in vitro drug-testing model, the authors identified three compounds, ebselen, wortmannin and PX-866, with therapeutic potential to alleviate Pom-associated pathological phenotypes in neurons derived from Pom-iPSCs. [Hum Mol Genet] Abstract Researchers showed that obtained murine iPSC-microglia and iPSC-macrophages were distinct cell populations, even though iPSC-macrophages could upregulate CX3CR1 expression when cultured within a neural environment. [Brain Behav Immun] Full Article The expression profile in genic and repetitive elements of feeder-independent naive embryonic cells resembled the 8-cell-to-morula stage in vivo, and only differed from feeder-dependent naive cells in genes involved in cell-cell/cell-matrix interactions. [Stem Cell Reports] Full Article | Graphical Abstract PSEN1ΔE9, APPswe, and APOE4 Confer Disparate Phenotypes in Human iPSC-Derived Microglia Investigators presented a physiologically relevant high-yield protocol for producing human microglia-like cells from induced pluripotent stem cells. Differentiation was directed with small molecules through primitive erythromyeloid progenitors to re-create microglial ontogeny from yolk sac. [Stem Cell Reports] Full Article | Press Release | Graphical Abstract Scientists developed an in vitro model of human ectodermal patterning, in which hESCs self-organized to form robust and quantitatively reproducible patterns corresponding to the complete medial-lateral axis of the embryonic ectoderm.

INDUSTRY NEWSBioCardia announced that the independent Data Safety Monitoring Board (DSMB) has completed its prespecified data review for the Phase III pivotal CardiAMP Heart Failure Trial, which included safety follow-up results on 35 patients and all additional data available on the 50 patients randomized in the trial as of August 31, 2019. [BioCardia, Inc.] Press Release BioRestorative Therapies Announces New Initiative to Target Polycystic Ovarian Syndrome BioRestorative Therapies, Inc. announced that it has expanded its “off-the-shelf” brown adipose derived stem cell therapeutic pipeline to target polycystic ovarian syndrome (PCOS). PCOS is the most common reproductive endocrine disease, and can often lead to infertility, with up to five million patients in the United States. [BioRestorative Therapies, Inc.] Press Release | |

POLICY NEWSSenate Bill Would Give NIH $3 Billion in 2020, or 7.7% Boost A Senate spending panel today released a draft 2020 spending bill containing a hefty $3 billion increase for the National Institutes of Health (NIH) that would bring the agency’s total budget to $42.1 billion. That 7.7% boost is $1 billion more than a House of Representatives committee approved in its version of the bill in April, and would amount to a 40% increase in NIH’s budget over the past 5 years. [ScienceMagazine] Editorial New Deals Could Help Scientific Societies Survive Open Access A project that included funders backing Plan S, the European-led effort to speed the transition to open access, released a set of contract templates and tips meant to help small, independent publishers reach deals with libraries that would eventually eliminate subscriptions while protecting revenue.
