  text: Homeostatic balance in the intestinal epithelium relies on a fast cellular
    turnover, which is coordinated by an intricate interplay between biochemical signalling,
    mechanical forces and organ geometry. We review recent modelling approaches that
    have been developed to understand different facets of this remarkable homeostatic
    equilibrium. Existing models offer different, albeit complementary, perspectives
    on the problem. First, biomechanical models aim to explain the local and global
    mechanical stresses driving cell renewal as well as tissue shape maintenance.
    Second, compartmental models provide insights into the conditions necessary to
    keep a constant flow of cells with well-defined ratios of cell types, and how
    perturbations can lead to an unbalance of relative compartment sizes. A third
    family of models address, at the cellular level, the nature and regulation of
    stem fate choices that are necessary to fuel cellular turnover. We also review
    how these different approaches are starting to be integrated together across scales,
    to provide quantitative predictions and new conceptual frameworks to think about
    the dynamics of cell renewal in complex tissues.

  text: The morphology and functionality of the epithelial lining differ along the
    intestinal tract, but tissue renewal at all sites is driven by stem cells at the
    base of crypts1,2,3. Whether stem cell numbers and behaviour vary at different
    sites is unknown. Here we show using intravital microscopy that, despite similarities
    in the number and distribution of proliferative cells with an Lgr5 signature in
    mice, small intestinal crypts contain twice as many effective stem cells as large
    intestinal crypts. We find that, although passively displaced by a conveyor-belt-like
    upward movement, small intestinal cells positioned away from the crypt base can
    function as long-term effective stem cells owing to Wnt-dependent retrograde cellular
    movement. By contrast, the near absence of retrograde movement in the large intestine
    restricts cell repositioning, leading to a reduction in effective stem cell number.
    Moreover, after suppression of the retrograde movement in the small intestine,
    the number of effective stem cells is reduced, and the rate of monoclonal conversion
    of crypts is accelerated. Together, these results show that the number of effective
    stem cells is determined by active retrograde movement, revealing a new channel
    of stem cell regulation that can be experimentally and pharmacologically manipulated.

  text: Embryo morphogenesis is impacted by dynamic changes in tissue material properties,
    which have been proposed to occur via processes akin to phase transitions (PTs).
    Here, we show that rigidity percolation provides a simple and robust theoretical
    framework to predict material/structural PTs of embryonic tissues from local cell
    connectivity. By using percolation theory, combined with directly monitoring dynamic
    changes in tissue rheology and cell contact mechanics, we demonstrate that the
    zebrafish blastoderm undergoes a genuine rigidity PT, brought about by a small
    reduction in adhesion-dependent cell connectivity below a critical value. We quantitatively
    predict and experimentally verify hallmarks of PTs, including power-law exponents
    and associated discontinuities of macroscopic observables. Finally, we show that
    this uniform PT depends on blastoderm cells undergoing meta-synchronous divisions
    causing random and, consequently, uniform changes in cell connectivity. Collectively,
    our theoretical and experimental findings reveal the structural basis of material
    PTs in an organismal context.

  text: Understanding to what extent stem cell potential is a cell-intrinsic property
    or an emergent behavior coming from global tissue dynamics and geometry is a key
    outstanding question of systems and stem cell biology. Here, we propose a theory
    of stem cell dynamics as a stochastic competition for access to a spatially localized
    niche, giving rise to a stochastic conveyor-belt model. Cell divisions produce
    a steady cellular stream which advects cells away from the niche, while random
    rearrangements enable cells away from the niche to be favorably repositioned.
    Importantly, even when assuming that all cells in a tissue are molecularly equivalent,
    we predict a common (“universal”) functional dependence of the long-term clonal
    survival probability on distance from the niche, as well as the emergence of a
    well-defined number of functional stem cells, dependent only on the rate of random
    movements vs. mitosis-driven advection. We test the predictions of this theory
    on datasets of pubertal mammary gland tips and embryonic kidney tips, as well
    as homeostatic intestinal crypts. Importantly, we find good agreement for the
    predicted functional dependency of the competition as a function of position,
    and thus functional stem cell number in each organ. This argues for a key role
    of positional fluctuations in dictating stem cell number and dynamics, and we
    discuss the applicability of this theory to other settings.

  text: 'In many real-world systems, information can be transmitted in two qualitatively
    different ways: by copying or by transformation. Copying occurs when messages
    are transmitted without modification, e.g. when an offspring receives an unaltered
    copy of a gene from its parent. Transformation occurs when messages are modified
    systematically during transmission, e.g. when mutational biases occur during genetic
    replication. Standard information-theoretic measures do not distinguish these
    two modes of information transfer, although they may reflect different mechanisms
    and have different functional consequences. Starting from a few simple axioms,
    we derive a decomposition of mutual information into the information transmitted
    by copying versus the information transmitted by transformation. We begin with
    a decomposition that applies when the source and destination of the channel have
    the same set of messages and a notion of message identity exists. We then generalize
    our decomposition to other kinds of channels, which can involve different source
    and destination sets and broader notions of similarity. In addition, we show that
    copy information can be interpreted as the minimal work needed by a physical copying
    process, which is relevant for understanding the physics of replication. We use
    the proposed decomposition to explore a model of amino acid substitution rates.
    Our results apply to any system in which the fidelity of copying, rather than
    simple predictability, is of critical relevance.'

  text: Understanding the thermodynamics of the duplication process is a fundamental
    step towards a comprehensive physical theory of biological systems. However, the
    immense complexity of real cells obscures the fundamental tensions between energy
    gradients and entropic contributions that underlie duplication. The study of synthetic,
    feasible systems reproducing part of the key ingredients of living entities but
    overcoming major sources of biological complexity is of great relevance to deepen
    the comprehension of the fundamental thermodynamic processes underlying life and
    its prevalence. In this paper an abstract—yet realistic—synthetic system made
    of small synthetic protocell aggregates is studied in detail. A fundamental relation
    between free energy and entropic gradients is derived for a general, non-equilibrium
    scenario, setting the thermodynamic conditions for the occurrence and prevalence
    of duplication phenomena. This relation sets explicitly how the energy gradients
    invested in creating and maintaining structural—and eventually, functional—elements
    of the system must always compensate the entropic gradients, whose contributions
    come from changes in the translational, configurational, and macrostate entropies,
    as well as from dissipation due to irreversible transitions. Work/energy relations
    are also derived, defining lower bounds on the energy required for the duplication
    event to take place. A specific example including real ternary emulsions is provided
    in order to grasp the orders of magnitude involved in the problem. It is found
    that the minimal work invested over the system to trigger a duplication event
    is around ~ 10−13J , which results, in the case of duplication of all the vesicles
    contained in a liter of emulsion, in an amount of energy around ~ 1kJ . Without
    aiming to describe a truly biological process of duplication, this theoretical
    contribution seeks to explicitly define and identify the key actors that participate
    in it.

  text: The emergence of syntax during childhood is a remarkable example of how complex
    correlations unfold in nonlinear ways through development. In particular, rapid
    transitions seem to occur as children reach the age of two, which seems to separate
    a two-word, tree-like network of syntactic relations among words from the scale-free
    graphs associated with the adult, complex grammar. Here, we explore the evolution
    of syntax networks through language acquisition using the chromatic number, which
    captures the transition and provides a natural link to standard theories on syntactic
    structures. The data analysis is compared to a null model of network growth dynamics
    which is shown to display non-trivial and sensible differences. At a more general
    level, we observe that the chromatic classes define independent regions of the
    graph, and thus, can be interpreted as the footprints of incompatibility relations,
    somewhat as opposed to modularity considerations.

  text: 'A major problem for evolutionary theory is understanding the so-called open-ended
    nature of evolutionary change, from its definition to its origins. Open-ended
    evolution (OEE) refers to the unbounded increase in complexity that seems to characterize
    evolution on multiple scales. This property seems to be a characteristic feature
    of biological and technological evolution and is strongly tied to the generative
    potential associated with combinatorics, which allows the system to grow and expand
    their available state spaces. Interestingly, many complex systems presumably displaying
    OEE, from language to proteins, share a common statistical property: the presence
    of Zipf''s Law. Given an inventory of basic items (such as words or protein domains)
    required to build more complex structures (sentences or proteins) Zipf''s Law
    tells us that most of these elements are rare whereas a few of them are extremely
    common. Using algorithmic information theory, in this paper we provide a fundamental
    definition for open-endedness, which can be understood as postulates. Its statistical
    counterpart, based on standard Shannon information theory, has the structure of
    a variational problem which is shown to lead to Zipf''s Law as the expected consequence
    of an evolutionary process displaying OEE. We further explore the problem of information
    conservation through an OEE process and we conclude that statistical information
    (standard Shannon information) is not conserved, resulting in the paradoxical
    situation in which the increase of information content has the effect of erasing
    itself. We prove that this paradox is solved if we consider non-statistical forms
    of information. This last result implies that standard information theory may
    not be a suitable theoretical framework to explore the persistence and increase
    of the information content in OEE systems.'
