    Enhancer-Promoter Interactions Are Reconfigured through the Formation of Long-Range Multiway Hubs as Mouse ES Cells Exit Pluripotency

    Scientists found that there was a remarkable reorganization of 3D genome structure where inter-chromosomal intermingling increased dramatically in the formative state.

    Precise and Scalable Self-Organization in Mammalian Pseudo-Embryos

    The authors investigated how precise and reproducible patterns of gene expression emerged in mammals by using gastruloids, a three-dimensional (3D) in vitro model for early mammalian development.

    Single-Cell Omics Identifies Inflammatory Signaling as a Trans-Differentiation Trigger in Mouse Embryos

    Researchers applied three scoring indexes of entropies, cell-type signature transcription factor expression, and critical transition signals to show common features underpinning the fate plasticity of transition states.

    Txnip Regulates the Oct4-Mediated Pluripotency Circuitry via Metabolic Changes upon Differentiation

    Scientists revealed the novel functions of mouse Txnip in cellular reprogramming and differentiation onset by involving in glucose-mediated histone acetylation and the regulation of Oct4, which was a fundamental component of the molecular circuitry underlying pluripotency.

    PRODH Safeguards Human Naive Pluripotency by Limiting Mitochondrial Oxidative Phosphorylation and Reactive Oxygen Species Production

    Investigators reported that, proline dehydrogenase (PRODH), a mitochondria-localized proline metabolism enzyme, was dramatically upregulated in naive hESCs compared to their primed counterparts.

    P53 and BCL-2 Family Proteins PUMA and NOXA Define Competitive Fitness in Pluripotent Cell Competition

    Investigators reported that P53 and its pro-apoptotic target PUMA and NOXA regulated apoptosis susceptibility and competitive fitness in pluripotent cells. PUMA was widely expressed specifically in pluripotent cells in vitro and in vivo.

    iPSC-Derived Models for Anorexia Nervosa Research

    The use of both organoids and spheroids, derived from either hESCs or hiPSCs would allow identification of cell type-specific changes associated with anorexia nervosa and comorbid diseases, to study preferential connections between brain areas and organs.

    Fetal Tissue Research Gains in Importance as Roadblocks Multiply

    Scientists at the University of Wisconsin-Madison have spent years trying to unravel the details of Down syndrome: What happens inside the womb, how the genetic disorder alters the formation of neurons, and what specific processes affect brain development. The work can’t proceed without studying fetal tissue.
