    GATA6 mutations in hiPSCs inform mechanisms for maldevelopment of the heart, pancreas, and diaphragm

    Arun Sharma, Lauren K Wasson ... Pediatric Cardiac Genomics Consortium
    Analyses of human stem cells with distinct GATA6 mutations revealed a spectrum of molecular responses that drive isolated congenital heart disease or the co-occurrence of pancreas and diaphragm malformations.

    CHD-associated enhancers shape human cardiomyocyte lineage commitment

    Daniel A Armendariz, Sean C Goetsch ... Gary C Hon
    Single-cell screens during human cardiomyocyte (CM) differentiation reveal that perturbation of congenital heart defect-linked enhancers/genes causes deficient CM differentiation.

    Early patterning and specification of cardiac progenitors in gastrulating mesoderm

    W Patrick Devine, Joshua D Wythe ... Benoit G Bruneau
    Multipotent cardiac precursors within a population of mesoderm are rapidly fated to specific anatomic locations in the developing mouse heart.

    A novel source of arterial valve cells linked to bicuspid aortic valve without raphe in mice

    Lorriane Eley, Ahlam MS Alqahtani ... Deborah J Henderson
    Identification of a novel source of progenitor cells that form arterial valve leaflets and that, when disrupted, can lead to bicuspid arterial valve, the most common human cardiac malformation.

    Recapitulating human cardio-pulmonary co-development using simultaneous multilineage differentiation of pluripotent stem cells

    Wai Hoe Ng, Elizabeth K Johnston ... Xi Ren
    An induced pluripotent stem-cell-based, human heart and lung co-differentiation model reveals their shared signaling requirement and enables investigation of their developmental mutual interaction and tissue boundary formation.

    Tgfβ signaling is critical for maintenance of the tendon cell fate

    Guak-Kim Tan, Brian A Pryce ... Ronen Schweitzer
    Conditional deletion of TGFβ signaling results in tenocyte dedifferentiation in vivo demonstrating a key role for TGFβ signaling in the maintenance of the tendon cell fate.

    Regulation of multiple signaling pathways promotes the consistent expansion of human pancreatic progenitors in defined conditions

    Luka Jarc, Manuj Bandral ... Anthony Gavalas
    The signaling requirements to decouple proliferation of pancreatic progenitors from differentiation were elucidated and employed for the reproducible expansion, under GMP-compliant conditions, of pancreatic progenitors derived from different human pluripotent stem cell lines.

    Live-cell imaging reveals enhancer-dependent Sox2 transcription in the absence of enhancer proximity

    Jeffrey M Alexander, Juan Guan ... Orion D Weiner
    Sox2 transcription is not correlated with spatial proximity of its essential regulatory enhancer in embryonic stem cells, suggesting gene transcription is not limited to periods of direct enhancer-promoter contact.
