    Single cell transcriptomics identifies a unique adipose lineage cell population that regulates bone marrow environment

    Leilei Zhong et al.
    A newly identified adipose lineage cell population, MALP, regulates marrow vasculature and osteogenesis in bone.

    The neural crest is a source of mesenchymal stem cells with specialized hematopoietic stem cell niche function

    Joan Isern et al.
    Developing long bones contain distinct mesenchymal stem-cell populations derived from mesoderm and neural crest, which have specialized functions in skeleton formation and the establishment of the hematopoietic stem-cell niche, respectively.

    Bone: A role for fat precursors in the marrow

    Noriaki Ono
    A group of cells that can become adipocytes controls the formation of blood vessels in the bone marrow, and also regulates the differentiation of resident mesenchymal progenitor cells.

    Philosophy of Biology: Characterizing causality in cancer

    Elena Rondeau et al.
    Ideas about causality from philosophy can help scientists to better understand how cancerous tumors grow and spread in the body.

    Chromatin accessibility dynamics and single cell RNA-Seq reveal new regulators of regeneration in neural progenitors

    Anneke Dixie Kakebeen et al.
    Regenerating neural progenitors of the Xenopus tropicalis tail prioritize differentiation to motor neuron types earlier than proliferation, a decision partly regulated by the transcription factors Pbx3 and Meis1.

    Dissecting the phenotypic and functional heterogeneity of mouse inflammatory osteoclasts by the expression of Cx3cr1

    Maria-Bernadette Madel et al.
    Osteoclasts emerging in inflammation are heterogeneous and encompass a strongly inflammatory subset with a high resorbing activity and an immune suppressive subset that are able to control each other.

    Progenitors oppositely polarize WNT activators and inhibitors to orchestrate tissue development

    Irina Matos et al.
    Progenitors establish a single-cell length WNT morphogen gradient to transmit signals directionally and differentially to neighbors.

    Developmental variability channels mouse molar evolution

    Luke Hayden et al.
    The nature and extent of developmental variation seen between mouse strains and genetically identical individuals explain why the first upper molar evolves along preferred path in murine rodents.
