    Cellular reprogramming with ATOH1, GFI1, and POU4F3 implicate epigenetic changes and cell-cell signaling as obstacles to hair cell regeneration in mature mammals

    Amrita A Iyer, Ishwar Hosamani ... Andrew K Groves
    Cells of the mammalian cochlea can be reprogrammed to produce mechanosensory hair cells, but epigenetic changes in the cochlea make this process less efficient with age.

    Multi-omic rejuvenation of human cells by maturation phase transient reprogramming

    Diljeet Gill, Aled Parry ... Wolf Reik
    Transiently reprogramming human fibroblasts up to the maturation phase rejuvenates cells according to several aging markers whilst enabling them to return to their original identity.

    Increasing Notch signaling antagonizes PRC2-mediated silencing to promote reprograming of germ cells into neurons

    Stefanie Seelk, Irene Adrian-Kalchhauser ... Rafal Ciosk
    Increased Notch signaling enhances germ cell reprograming in C. elegans by antagonizing PRC2-mediated repression, which results in the activation of UTX-1 and other reprograming-promoting genes.

    16p11.2 microdeletion imparts transcriptional alterations in human iPSC-derived models of early neural development

    Julien G Roth, Kristin L Muench ... Theo D Palmer
    A model of in vitro human corticogenesis identifies alterations in gene expression caused by loss of 16p11.2 CNV genes in hiPSC-derived progenitor cells.

    Mouse embryonic stem cells can differentiate via multiple paths to the same state

    James Alexander Briggs, Victor C Li ... Marc W Kirschner
    Single cell RNA sequencing reveals that mouse embryonic stem cells can be differentiated into the same terminal motor neuron state via distinct differentiation paths, one of which includes a surprising intermediate state not found in embryos.

    A test of the pioneer factor hypothesis using ectopic liver gene activation

    Jeffrey L Hansen, Kaiser J Loell, Barak A Cohen
    Pioneering activity may be a property of all transcription factors with sufficient affinity for their targets rather than a property of specific classes of transcription factors.

    Multi-omics characterization of partial chemical reprogramming reveals evidence of cell rejuvenation

    Wayne Mitchell, Ludger JE Goeminne ... Vadim N Gladyshev
    Partial chemical reprogramming is able to reduce the biological age of cells by diverting them to a different metabolic state marked by a strong upregulation of mitochondrial oxidative phosphorylation.

    Lactate-mediated epigenetic reprogramming regulates formation of human pancreatic cancer-associated fibroblasts

    Tushar D Bhagat, Dagny Von Ahrens ... Amit Verma
    Lactate in pancreatic cancer micro-environment can lead to TET enzyme activation and loss of DNA methylation seen in cancer associated fibroblasts.

    SRSF3 promotes pluripotency through Nanog mRNA export and coordination of the pluripotency gene expression program

    Madara Ratnadiwakara, Stuart K Archer ... Minna-Liisa Anko
    RNA-binding protein SRSF3 mediates critical changes in RNA processing of pluripotency genes, which reveals functional consequences of regulated RNA processing during stem cell self-renewal and early development.
