    Basal-like breast cancer is a heterogeneous disease with poor prognosis; however, its cellular origins and aetiology are poorly understood. Here the authors provide evidence that ID4 is a key controller of mammary stem/progenitor cell self-renewal, acting upstream of Notch signalling to repress luminal fate commitment.

    Laminin-511 and its cell-binding domain support long-term self-renewal of human pluripotent stem cells in xeno-free culture conditions. Here the authors show that a xeno-free culture matrix consisting of a full-length laminin-521 and the cell–cell adhesion protein E-cadherin supports clonal expansion of human embryonic stem cells.

    Satellite cells have important roles in homeostasis and regeneration of skeletal muscles. Urciuolo et al. show that the extracellular matrix protein collagen VI is required for preserving satellite cell self-renewal and muscle regeneration in vitro and in vivoby modulating muscle mechanical properties.

    While human embryonic stem cells (ESC) hold great therapeutic promise, many aspects of their basic biology remain poorly understood. Conklin et al.show that too much or too little activation of RB family proteins is detrimental to human ESC populations and identify unique cell cycle regulatory networks in these cells.

    Embryonic stem cells have a shortened cell cycle that allows for rapid proliferation, but the exact mechanisms are unclear. Here, a microRNA target, Trim71, is shown to inhibit the expression of a cyclin-dependent kinase inhibitor, thus enabling the G1–S phase cell cycle transition in embryonic stem cells.

    Stem cells are thought to be tethered in their niche via adhesion molecules and the inhibition of cell differentiation. Here, the authors screened for genes required for maintainingDrosophilaovarian follicle stem cells and found their function to depend on cell proliferation, mitochondrial function and niche adhesion.

    Asymmetric partitioning of centrosomes has been reported inDrosophilaneuroblasts, but whether this type of division has implications for stem cell self-renewal is unclear. In this study, the authors show that the asymmetric division of the centrosomes correlates with the asymmetric fate of the cells and that the daughter centrosome is retained by the neuroblast.

    When cultured as single cells, embryonic stem cells have low viability. Here, blebbistatin, a non-muscle myosin II inhibitor, is shown to enhance the cloning efficiency, viability and adhesion of both human embryonic stem cells and human induced pluripotent stem cellsin vitro.
