    Cell Reprogramming-Inspired Dynamically Responsive Hydrogel Boosts the Induction of Pluripotency via Phase-Separated Biomolecular Condensates

    Cell reprogramming-inspired dynamically responsive hydrogel was fabricated via a synthetic biology-based strategy. Human and mouse somatic cells had been efficiently reprogrammed into iPSCs that exhibited key features of ESCs.

    Quantitative Haplotype-Resolved Analysis of Mitochondrial DNA Heteroplasmy in Human Single Oocytes, Blastoids, and Pluripotent Stem Cells

    Scientists used their individual Mitochondrial Genome sequencing technology to study mitochondrial DNA (mtDNA) heterogeneity, quantitate single nucleotide variants and large structural variants, track heteroplasmy dynamics, and analyze genetic linkage between variants at the individual mtDNA molecule level in single oocytes and human blastoids.

    A Human Induced Pluripotent Stem Cell Model from a Patient with Hereditary Cerebral Small Vessel Disease Carrying a Heterozygous R302Q Mutation in HTRA1

    Researchers reported the first establishment of a hiPSC line from a patient with heterozygous high-temperature requirement serine peptidase A1 (HTRA1)-related cerebral small vessel disease.

    Crotonylation of GAPDH Regulates Human Embryonic Stem Cell Endodermal Lineage Differentiation and Metabolic Switch

    The authors investigated the role of crotonylation in hESC differentiation by introduce crotonate into the culture medium of GFP tagged LTR7 primed H9 cell and extended PSC lines.

    Differentiation of Uniparental Human Embryonic Stem Cells into Granulosa Cells Reveals a Paternal Contribution to Gonadal Development

    Investigators differentiated androgenetic and parthenogenetic hPSCs into ovarian granulosa-like cells (GLCs). They showed that in contrast to biparental and androgenetic cells, parthenogenetic hPSCs presented a reduced capacity to differentiate into GLCs.

    Static Magnetic Fields Promote Generation of Muscle Lineage Cells from Pluripotent Stem Cells and Myoblasts

    Researchers showed that static magnetic fields (SMFs) promoted the expression of the core pluripotent markers Sox2 and SSEA-1. Furthermore, SMFs facilitated the differentiation of ESCs into cardiomyocytes and skeletal muscle cells.

    An In Vitro Culture Platform for Studying the Effect of Collective Cell Migration on Spatial Self-Organization within Induced Pluripotent Stem Cell Colonies

    Scientists developed an hiPSC-based model to study the effect of collective cell migration in meso–endodermal lineage segregation and cell fate decisions through the control of space confinement using a detachable ring culture system.

    UPF3A Is Dispensable for Nonsense-Mediated mRNA Decay in Mouse Pluripotent and Somatic Cells

    Investigators generated a Upf3a conditional knockout mouse strain and established multiple lines of ESCs and somatic cells without UPF3A. UPF3A neither repressed nonsense-mediated mRNA decay in mouse ESCs, somatic cells, nor in major organs including the liver, spleen, and thymus.

    ZBTB7A Regulates Primed-to-Naïve Transition of Pluripotent Stem Cells via Recognition of the PNT-Associated Sequence by Zinc Fingers 1–2 and Recognition of γ-Globin −200 Gene Element by Zinc Fingers 1–4

    Researchers reported a crystal structure of ZBTB7A zinc finger (ZF) 1–3 in complex with the primed-to-naïve transition (PNT) associated sequence.
