    Cell and molecular transitions during efficient dedifferentiation

    John ME Nichols, Vlatka Antolović ... Jonathan R Chubb
    Efficient dedifferentiation is characterized by robustness to mutation, flexibility in ordering of cellular events and reversal of developmental changes along a single gene expression trajectory.

    JNK signaling triggers spermatogonial dedifferentiation during chronic stress to maintain the germline stem cell pool in the Drosophila testis

    Salvador C Herrera, Erika A Bach
    JNK pathway activity induces spermatogonial dedifferentiation under challenging conditions to maintain the germline stem cell pool and to endow it with potentially fitter cells that have increased proliferation.

    NFATc1 marks articular cartilage progenitors and negatively determines articular chondrocyte differentiation

    Fan Zhang, Yuanyuan Wang ... Xianpeng Ge
    NFATc1 is identified as a molecular marker of articular cartilage progenitor cells and a transcriptional repressor of chondrocyte differentiation, providing fundamental insights into the origin and differentiation mechanism of articular chondrocytes.

    Single-cell analysis reveals dynamics of human B cell differentiation and identifies novel B and antibody-secreting cell intermediates

    Niels JM Verstegen, Sabrina Pollastro ... S Marieke van Ham
    Single-cell RNA sequencing provides a detailed understanding of the cues controlling in vitro differentiation of human B cells into antibody-secreting cells (ASCs), uncovering a novel pre-ASC population present ex vivo in lymphoid tissues that progress through a germinal center-like state.

    The kinase PDK1 is critical for promoting T follicular helper cell differentiation

    Zhen Sun, Yingpeng Yao ... Shuyang Yu
    PDK1 serves as a critical role for intrinsically promoting T follicular helper cell differentiation and effector functions via controlling expression level of TCF1.

    Yap1 safeguards mouse embryonic stem cells from excessive apoptosis during differentiation

    Lucy LeBlanc, Bum-Kyu Lee ... Jonghwan Kim
    During ES cell differentiation, Yap1 directly regulates apoptosis-related genes like Bcl-2 and Mcl-1 to attenuate apoptosis and promote cell survival to allow for successful cell fate changes.

    Enhancer regions show high histone H3.3 turnover that changes during differentiation

    Aimee M Deaton, Mariluz Gómez-Rodríguez ... Robert E Kingston
    Nucleosomes at enhancers are unusually dynamic and change histone turnover rates during differentiation.

    The Brm-HDAC3-Erm repressor complex suppresses dedifferentiation in Drosophila type II neuroblast lineages

    Chwee Tat Koe, Song Li ... Hongyan Wang
    A novel complex composed of various components of a chromatin remodeling complex, a chromatin remodeling factor and a transcription factor suppresses the dedifferentiation of intermediate neural progenitors back into neuroblasts in Drosophila.

    Dynamics of embryonic stem cell differentiation inferred from single-cell transcriptomics show a series of transitions through discrete cell states

    Sumin Jang, Sandeep Choubey ... Sharad Ramanathan
    Mammalian germ layer differentiation is characterized by transitions through discrete cell states, which are transcriptionally as well as functionally distinct.

    Mutationally-activated PI3’-kinase-α promotes de-differentiation of lung tumors initiated by the BRAFV600E oncoprotein kinase

    J Edward van Veen, Michael Scherzer ... Martin McMahon
    Two of the most commonly mutated growth factor pathways induce a deadly feature of lung adenocarcinoma.
