Cellular mechanisms of morphogenesis.
The development and functions of multicellular organisms ely on the local activities of cells and molecules. Advances in icroscopy have made it possible to visualize directly dynamic ssemblies of cells as they grow, divide, and morph into the recgnizable structures that make up a fully formed animal. However, he rules that determine how cells interact, and how these interacions produce the elab...
متن کاملPathways of Cellular Morphogenesis
Evidence is presented to show that a given change in cell form or size may generally be brought about by a variety of patterns of local surface distortion and expansion. Structural and chemical features of the cell which are important in morphogenesis may thus be expected to relate not to form per se but to the kinetics of surface behavior which establish form. These kinetics evaluate both the ...
متن کاملTooth morphogenesis in vivo, in vitro, and in silico.
One of the aims of developmental biology is to understand how a single egg cell gives rise to the complex spatial distributions of cell types and extracellular components of the adult phenotype. This review discusses the main genetic and epigenetic interactions known to play a role in tooth development and how they can be integrated into coherent models. Along the same lines, several hypotheses...
متن کاملIn-silico prediction of Cellular Responses to Polymeric Biomaterials from Their Molecular Descriptors
In this work quantitative structure activity relationship (QSAR) methodology was applied for modeling and prediction of cellular response to polymers that have been designed for tissue engineering. After calculation and screening of molecular descriptors, linear and nonlinear models were developed by using multiple linear regressions (MLR) and artificial neural network (ANN) methods. The root m...
متن کاملKidney morphogenesis: cellular and molecular regulation
Development of an organ is directed by cell and tissue interactions and these also occur during the formation of functional kidney. During vertebrate development inductive signalling between mesenchyme and epithelium controls the organogenesis of all three kinds of kidneys: pronephros, mesonephros and metanephros. In higher animals the metanephros differentiates into the permanent kidney and in...
