  text: 'Vertebrates display remarkable diversity of sensorimotor behaviors, each
    adapted to distinct ecological and survival demands. This diversity raises fundamental
    questions about the evolutionary origin of motor control: do conserved spinal
    circuits underlie these behaviors, and how have they diverged across species.
    Recent studies detail spinal cell-type architecture in mammals but comparable,
    high-resolution atlases of the non-mammalian spinal cord are lacking. Here, we
    compare spinal cord cell types between fish, frogs, mice and humans, spanning
    ∼450 million years of evolution. Across species, we define highly conserved programs
    of cell type specification that segregate spinal neurons into nearly identical
    cardinal classes during development. This contrasts with adult stages, when spinal
    cell-type composition selectively diverges for excitatory neuron subpopulations.
    Using spatial transcriptomics, we localize this species divergence to the superficial,
    dorsal spinal cord, where variant neuropeptide expression defines mammalian-specific
    cell types. The most dorsal spinal cord thus emerges as a recently evolved hub
    for sensory integration in mammals, a neospinal cord analogous to the neocortex.</jats:p>'

  text: Regulation of chromatin states involves the dynamic interplay between different
    histone modifications to control gene expression. Recent advances have enabled
    mapping of histone marks in single cells, but most methods are constrained to
    profile only one histone mark per cell. Here, we present an integrated experimental
    and computational framework, scChIX-seq (single-cell chromatin immunocleavage
    and unmixing sequencing), to map several histone marks in single cells. scChIX-seq
    multiplexes two histone marks together in single cells, then computationally deconvolves
    the signal using training data from respective histone mark profiles. This framework
    learns the cell-type-specific correlation structure between histone marks, and
    therefore does not require a priori assumptions of their genomic distributions.
    Using scChIX-seq, we demonstrate multimodal analysis of histone marks in single
    cells across a range of mark combinations. Modeling dynamics of in vitro macrophage
    differentiation enables integrated analysis of chromatin velocity. Overall, scChIX-seq
    unlocks systematic interrogation of the interplay between histone modifications
    in single cells.

  text: 'Post-translational histone modifications modulate chromatin activity to affect
    gene expression. How chromatin states underlie lineage choice in single cells
    is relatively unexplored. We develop sort-assisted single-cell chromatin immunocleavage
    (sortChIC) and map active (H3K4me1 and H3K4me3) and repressive (H3K27me3 and H3K9me3)
    histone modifications in the mouse bone marrow. During differentiation, hematopoietic
    stem and progenitor cells (HSPCs) acquire active chromatin states mediated by
    cell-type-specifying transcription factors, which are unique for each lineage.
    By contrast, most alterations in repressive marks during differentiation occur
    independent of the final cell type. Chromatin trajectory analysis shows that lineage
    choice at the chromatin level occurs at the progenitor stage. Joint profiling
    of H3K4me1 and H3K9me3 demonstrates that cell types within the myeloid lineage
    have distinct active chromatin but share similar myeloid-specific heterochromatin
    states. This implies a hierarchical regulation of chromatin during hematopoiesis:
    heterochromatin dynamics distinguish differentiation trajectories and lineages,
    while euchromatin dynamics reflect cell types within lineages.'
