Bone morphogenetic protein 4 (BMP4) is key for early cardiac mesoderm induction in hPSC and subsequent cardiomyocyte derivation. Small‐molecular BMP4 mimetics may help to standardize cardiomyocyte derivation from hPSCs. Based on observations that chalcones can stimulate BMP4 signaling pathways, we hypothesized their utility in cardiac mesoderm induction. To test this, we set up a two‐tiered screening strategy, (1) for directed differentiation of hPSCs with commercially available chalcones (4’‐hydroxychalcone [4’HC] and Isoliquiritigen) and 24 newly synthesized chalcone derivatives, and (2) a functional screen to assess the propensity of the obtained cardiomyocytes to self‐organize into contractile engineered human myocardium (EHM). We identified 4’HC, 4‐fluoro‐4’‐methoxychalcone, and 4‐fluoro‐4’‐hydroxychalcone as similarly effective in cardiac mesoderm induction, but only 4’HC as an effective replacement for BMP4 in the derivation of contractile EHM‐forming cardiomyocytes."],["dc.description.abstract","Have a little heart: A screen for mesoderm inducing chalcones in human pluripotent stem cell cultures identified 4’‐hydroxychalcone (4’HC) as an effective replacement for bone‐morphogenetic protein 4 (BMP4) in supporting the derivation of engineered heart muscle (EHM)‐formation competent cardiomyocytes. image"],["dc.description.sponsorship","German Center for Cardiovascular Research"],["dc.description.sponsorship","German Federal Ministry for Science and Education"],["dc.description.sponsorship","German Research Foundation http://dx.doi.org/10.13039/501100001659"],["dc.description.sponsorship","Fondation Leducq http://dx.doi.org/10.13039/501100001674"],["dc.identifier.doi","10.1002/cmdc.202100222"],["dc.identifier.pmid","34309224"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/90137"],["dc.identifier.url","https://mbexc.uni-goettingen.de/literature/publications/432"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-469"],["dc.relation","EXC 2067: Multiscale Bioimaging"],["dc.relation.eissn","1860-7187"],["dc.relation.issn","1860-7179"],["dc.relation.workinggroup","RG Zimmermann (Engineered Human Myocardium)"],["dc.rights","This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited."],["dc.title","Chalcone‐Supported Cardiac Mesoderm Induction in Human Pluripotent Stem Cells for Heart Muscle Engineering"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

Tephra from this eruption has been spread over vast areas in Asia, where it constitutes a major time marker close to the Marine Isotope Stage 4/5 boundary. As yet, no tephra associated with Toba has been identified in Greenland or Antarctic ice cores. Based on new accurate dating of Toba tephra and on accurately dated European stalagmites, the Toba event is known to occur between the onsets of Greenland interstadials (GI) 19 and 20. Furthermore, the existing linking of Greenland and Antarctic ice cores by gas records and by the bipolar seesaw hypothesis suggests that the Antarctic counterpart is situated between Antarctic Isotope Maxima (AIM) 19 and 20. In this work we suggest a direct synchronization of Greenland (NGRIP) and Antarctic (EDML) ice cores at the Toba eruption based on matching of a pattern of bipolar volcanic spikes. Annual layer counting between volcanic spikes in both cores allows for a unique match. We first demonstrate this bipolar matching technique at the already synchronized Laschamp geomagnetic excursion (41 ka BP) before we apply it to the suggested Toba interval. The Toba synchronization pattern covers some 2000 yr in GI-20 and AIM19/20 and includes nine acidity peaks that are recognized in both ice cores. The suggested bipolar Toba synchronization has decadal precision. It thus allows a determination of the exact phasing of inter-hemispheric climate in a time interval of poorly constrained ice core records, and it allows for a discussion of the climatic impact of the Toba eruption in a global perspective. The bipolar linking gives no support for a long-term global cooling caused by the Toba eruption as Antarctica experiences a major warming shortly after the event. Furthermore, our bipolar match provides a way to place palaeo-environmental records other than ice cores into a precise climatic context."],["dc.identifier.doi","10.5194/cp-9-749-2013"],["dc.identifier.isi","000317009700016"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10609"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/31225"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Copernicus Gesellschaft Mbh"],["dc.relation.issn","1814-9332"],["dc.relation.issn","1814-9324"],["dc.relation.orgunit","Fakultät für Geowissenschaften und Geographie"],["dc.rights","CC BY 3.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/3.0/"],["dc.title","Direct linking of Greenland and Antarctic ice cores at the Toba eruption (74 ka BP)"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
