    Unreprogrammed H3K9me3 Prevents Minor Zygotic Genome Activation and Lineage Commitment in SCNT Embryos

    Investigators performed genome-wide profiling of H3K9me3 in cumulus cell-derived somatic cell nuclear transfer (SCNT) embryos. They found redundant H3K9me3 marks were closely related to defective minor zygotic genome activation.

    Rhox6 Regulates the Expression of Distinct Target Genes to Mediate Mouse PGCLC Formation and ESC Self-Renewal

    Scientists found that overexpression of Rhox6 favored the formation of primordial germ cell-like cells (PGCLCs), while depletion of Rhox6 inhibited the generation of PGCLCs.

    Xeno-Free Generation of Human Induced Pluripotent Stem Cells from Donor-Matched Fibroblasts Isolated from Dermal and Oral Tissues

    iPSCs were generated via a platelet lysate or fetal bovine serum-based culturing protocol from matched dermal, buccal, and gingival human fibroblasts, isolated from healthy donors after informed consent, via episomal plasmid transfection.

    FACT Regulates Pluripotency through Proximal and Distal Regulation of Gene Expression in Murine Embryonic Stem Cells

    To explore the mechanism for FAcilitates Chromatin Transactions (FACT) function, investigators generated auxin-inducible degron-tagged murine embryonic cell lines for FACT subunit suppressor of Ty 16 homolog and paired depletion with nascent transcription and chromatin accessibility analyses.

    Single-Cell RNA-Seq Analysis of a Human Embryonic Stem Cell to Endothelial Cell System Based on Transcription Factor Overexpression

    The high-efficiency human ESC-endothelial cell induction system was established in a previous study. Scientists applied single-cell RNA sequencing of the differentiated cells at different time points and investigated the gene expression profiles.

    Dynamic Nucleosome Remodeling Mediated by YY1 Underlies Early Mouse Development

    Using a low-input MNase-seq method, researchers showed that nucleosome positioning was globally obscured in zygotes but became well-defined during subsequent development.
