    iPS-Cell-Derived Microglia Promote Brain Organoid Maturation via Cholesterol Transfer

    Scientists generated microglia-sufficient brain organoids by coculturing brain organoids with primitive-like macrophages generated from the same human iPSCs.

    Mammalian Oocytes Store Proteins for the Early Embryo on Cytoplasmic Lattices

    Investigators suggested that cytoplasmic lattices enrich maternally provided proteins to prevent their premature degradation and cellular activity, thereby enabling early mammalian development.

    NR5A2 Connects Zygotic Genome Activation to the First Lineage Segregation in Totipotent Embryos

    Researchers investigated the role of nuclear receptor transcription factors, whose motifs were highly enriched and accessible from the 2-cell to 8-cell stages in mouse embryos.

    Generation of Glucocorticoid-Producing Cells Derived from Human Pluripotent Stem Cells

    The authors reported the generation of large numbers of human-induced steroidogenic cells (hiSCs) from hPSCs. Directed differentiation of hPSCs into hiSCs recapitulates the initial stages of human adrenal development.

    Signaling Pathway Crosstalk Stimulated by L-proline Drives Mouse Embryonic Stem Cells to Primitive-Ectoderm-Like Cells

    Scientists utilized a factorial experimental design coupled with statistical modelling to understand which signaling pathways are involved in the transition between ESCs and early primitive ectoderm-like cells.

    Abstract

    Impact of the Overexpression of the Tyrosine Kinase Receptor (RET) in the Hematopoietic Potential of Induced Pluripotent Stem Cells (iPSCs)

    To test the implication of RET on the hematopoietic potential of iPSCs, researchers activated its pathway with the lentiviral overexpression of RETWT or RETC634Y mutation in normal iPSCs.

    Abstract

    Glutamate Secretion by Embryonic Stem Cells as an Autocrine Signal to Promote Proliferation

    Scientists performed biological analyses to identify the key components involved in glutamate biosynthesis, packaging for secretion, reaction, and reuptake in ESCs, including glutaminase, vesicular glutamate transporter, glutamate N-methyl-D-aspartate receptor, and cell membrane excitatory amino-acid transporter.

    Small Molecule-Mediated Reprogramming of Xenopus Blastula Stem Cells to a Neural Crest State

    Researchers reported a protocol for small molecule-mediated induction of the neural crest state from blastula stem cells and validated it using transcriptome analysis and grafting experiments.

    Generation, Characterization, and Differentiation of Induced Pluripotent Stem-Like Cells in the Domestic Cat

    Investigators derived iPS cells from cat embryonic fibroblasts retrovirally transfected with mouse Oct3/4, Klf4, Sox2, and c-Myc. After transfection, embryonic fibroblasts were reseeded onto inactivated SNL 76/7 and cultured in a medium supplemented with basic fibroblast growth factor.

    Novel Strategies for Angiogenesis in Tissue Injury: Therapeutic Effects of iPSCs-Derived Exosomes

    The authors focus on the mechanism of the angiogenic effect of iPSCs-derived exosomes on wound repair in tissue injury and their potential therapeutic targets, with a view to providing a theoretical basis for the use of iPSCs-derived exosomes in clinical therapy.

    ‘We Need More Women,’ Says Only Female Winner of Millennium Technology Prize

    As a Nobel laureate, Prof Frances Arnold is not short of accolades. Yet being the only woman to so far win the Millennium Technology Prize – the Nobel equivalent for engineers – is one of the least appealing.
