Branching morphogenesis is definitely a developmental mechanism by which patterns are generated in many developing organs, which is definitely controlled by underlying molecular pathways. Understanding the relationship between molecular signaling, cellular behavior and producing morphological switch requires quantification and categorization of the cellular behavior. In this study, tissue-level and cellular changes in developing salivary gland in response to disruption of ROCK-mediated signaling by are modeled by building cell-graphs to compute mathematical features taking structural properties at multiple scales. These features were used to generate multiscale cell-graph signatures of untreated and ROCK signaling disrupted salivary gland organ explants. From confocal images of mouse submandibular salivary gland organ explants in which epithelial and mesenchymal nuclei were marked, a multiscale feature collection capturing global structural properties, local structural properties, spectral, and morphological properties of the cells was derived. Six feature selection algorithms and multiway modeling of the data was performed to identify unique subsets of cell graph features that can distinctively classify and differentiate between different cell populations. Multiscale cell-graph analysis was most effective in classification of the cells state. Cellular and tissue organization, as defined by a multiscale subset of cell-graph features, are both quantitatively unique in epithelial and mesenchymal cell types both in the presence and absence of ROCK inhibitors. Whereas tensor analysis demonstrate that epithelial cells was affected probably the most by inhibition of ROCK signaling, significant multiscale changes in mesenchymal cells organization were recognized with this analysis that were not identified in earlier biological studies. We here show how to define and determine a multiscale feature arranged as an effective computational approach to determine and quantify changes at multiple biological scales and to distinguish between different claims in developing cells. Intro Morphological and practical development of organs necessitates generation of multiple cell types and their coordinated spatio-temporal set up. Branching morphogenesis is definitely a fundamental process controlling the growth and functional development of many mammalian exocrine glands such as the lung, kidney, pancreas, prostate glands, mammary glands and salivary glands [1]. During development of major exocrine organs, the process of branching morphogenesis was used to satisfy the requirement for efficient exchange of gases, nutrients, metabolites, and wastes with the environment. Branching morphogenesis enables packing of a large surface area of epithelium into a relatively small volume, therefore increasing the surface area in contact with the environment. Important questions concerning the signals controlling branching, what patterns are followed by the organs, and how these motions are controlled at cellular and cells level are just beginning to become explored. Recent studies in another organ that undergoes branching morphogenesis, the developing lung, recognized a set of three stereotypical geometric subroutine patterns that when reiteratively combined result in an adult lung [2]. The branching pattern in the developing salivary gland is different than in the lung since the gland undergoes a series of cleft formation events rather than the bifurcation events that happen during lung development [3]. Since the branching pattern in salivary gland is different and the morphological patterns are less apparent in the cells level than in the lung, we investigated whether a computational approach could be used to identify, quantify, and designate the cellular and cells level business of developing salivary glands as a first step in understanding the processes controlling organogenesis.
