From molecules to organs, levels are interrelated and interdependent, to ensure that the organism is in a position to conserve and adapt the integrity of its structural and functional organization against a back-drop of continuous alterations within the organism and its environment. That function represents the updated interpretation of homeostasis, a idea formulated a century ago by W.Nded on experimental basis, represents an additional discontinuity point with respect to SMT which posits that "biologicalinformation" carried out by genes constitutes the only (or the key) causative element in driving cellular fate and behavior.five levels. This will likely result in models of tissues and organisms with enhanced predictive energy [114]. Second, tissue and cytoskeleton/nucleoskeleton architecture, as well as mechanical forces (stiffness, shear strain [115], and surface tension), must be adequately weighted and investigated, a rather uncommon request for any "traditional" biologist [116]. Third, molecular and genetic changes, involving both the epithelial and the stromal cells, really should thus be investigated in association and linked for the observed modification with the context. Despite the fact that significantly has been learned about molecular components and subcellular processes, the integration of data and models across a wide selection of spatial and temporal scales, taking us from observations at the cellular or subcellular level to know tissue level phenomena, remains an unchartered territory. In addition, biophysical influences on cell behavior and differentiation is often adequately appreciated only by studying cells in their three-dimensional context and are for that reason disregarded by current experimental methodologies practically fully determined by 2D cultures. All round, these considerations highlight one more basic bias of modern day biology, that is certainly, the lack of a basic theory for understanding biological organization. In order to cope together with the increasingly appreciated complexity of living organism, implicitly, biologists have adopted a reductive strategy, primarily according to a gene-centric paradigm, exactly where causative processes are modelled based on a simplified, linear dynamics. Nonetheless, reality is much more complex than the biochemical diagrams we're asked to trust. Biological complexity entails nonlinear dynamics, stochastic gene expression, interactions among biochemical and biophysical variables, and events acting simultaneously at different levels. From molecules to organs, levels are interrelated and interdependent, in order that the organism is capable to conserve and adapt the integrity of its structural and functional organization against a back-drop of continuous adjustments inside the organism and its atmosphere. That feature represents the updated interpretation of homeostasis, a notion formulated a century ago by W. Cannon and currently reinterpreted as autoconservation [117], functional stability [118], evolvability, or robustness [119]. Offered that homeostasis is significantly threatened or perhaps disrupted within the course of quite a few diseases, to understand such processes we are obligatory essential to apply methodologies that discover nonlinear spatiotemporal systems with multiple levels of structural and functional organization. Even though substantially has been discovered about molecular components and subcellular processes, the integration of information and models across a wide range of spatial and temporal scales, taking us from observations in the cellular or subcellular level to understand tissue level phenomena, remains an unchartered territory.
