    Multiple inputs ensure yeast cell size homeostasis during cell cycle progression

    Cecilia Garmendia-Torres et al.
    Yeast cell size homeostasis is not controlled by a G1-specific mechanism alone but is likely to be an emergent property resulting from the integration of several mechanisms that coordinate cell and bud growth with division.

    Homeostatic control of START through negative feedback between Cln3-Cdk1 and Rim15/Greatwall kinase in budding yeast

    Nicolas Talarek et al.
    Inhibition of phosphatases by kinases develops Whi5 phosphorylation and cell cycle function in low cyclin-dependent kinase activity.

    Spatial correlations constrain cellular lifespan and pattern formation in corneal epithelium homeostasis

    Lior Strinkovsky et al.
    Rejuvenation of corneal epithelium in homeostasis is determined by the interplay between corneal cells replicative lifespan and the spatial correlation between cell replication and cell removal.

    YAP regulates cell size and growth dynamics via non-cell autonomous mediators

    Douaa Mugahid et al.
    Besides a cell autonomous role in regulating proliferation, YAP regulates the production of several extracellular molecules allowing for population-level coordination of cell growth and death.

    Positional information specifies the site of organ regeneration and not tissue maintenance in planarians

    Eric M Hill, Christian P Petersen
    Homeostatic tissue maintenance can occur at locations distinct from the target sites of organ regeneration planarians.

    A population of adult satellite-like cells in Drosophila is maintained through a switch in RNA-isoforms

    Hadi Boukhatmi, Sarah Bray
    Adult muscle progenitors evade differentiation by expressing a short RNA isoform of Zfh1 which is insensitive to regulation by a micro-RNA.

    A novel role for the root cap in phosphate uptake and homeostasis

    Satomi Kanno et al.
    Real-time 33P imaging combined with specific complementation of inorganic phosphate transport in the root cap reveals this tissue’s contribution to phosphate uptake.

    CDK control pathways integrate cell size and ploidy information to control cell division

    James Oliver Patterson et al.
    DNA concentration, cyclin levels, phosphatase activity, and CDK phosphorylation combine to directly link cell size to cell division.

    Myofiber-specific TEAD1 overexpression drives satellite cell hyperplasia and counters pathological effects of dystrophin deficiency

    Sheryl Southard et al.
    For skeletal muscle in mice, the size of the stem cell pool can be uncoupled from overall tissue size allowing for a dramatic increase in stem cell number.

    A first order phase transition mechanism underlies protein aggregation in mammalian cells

    Arjun Narayanan et al.
    Quantitative single molecule and super resolution imaging in mammalian cells reveal a population of precursor aggregates describable by first order phase transition theory.
