Morphogenesis is the process that underpins the selforganised development and regeneration of biological systems. The ability to mimick morphogenesis in artificial systems has great potential for many engineering applications, including production of biological tissue, design of robust electronic systems and the co-ordination of parallel computing. Previous attempts to mimick these complex dyna...

Islets of Langerhans are microorgans scattered throughout the pancreas, and are responsible for synthesizing and secreting pancreatic hormones. While progress has recently been made concerning cell differentiation of the islets of Langerhans, the mechanism controlling islet morphogenesis is not known. It is thought that these islets are formed by mature cell association, first differentiating i...

Recent experimental work in lung morphogenesis has described an elegant pattern of branching phenomena. Two primary forms of branching have been identified: side branching and tip splitting. In our previous study of lung branching morphogenesis, we used a 4 variable partial differential equation (PDE), due to Meinhardt, as our mathematical model to describe the reaction and diffusion of morphog...

on this project we try to calculated power of hydrogen on dycarbonil compound in different ways ; the first way is shoster way , for sain power of hydrogen notice the different power between central conforms on it and main conform that’s didn’t have hydrogen joint . or in other way different of energy between open and close form. second way, is average way? this is for way that studied conf...

A plethora of computational models have been developed in recent decades to account for the morphogenesis complex biological fluid networks, such as capillary beds. Contemporary adaptation are based on optimization schemes where networks react and adapt vessel conductance toward given flow patterns. Recent numeric studies network morphogenesis, incorporating uptake metabolites by embedding tiss...

Drought stress is a major environmental challenge that adversely affects plant growth and development. Auxin, vital hormone, plays crucial role in various aspects of development morphogenesis, ranging from embryogenesis to senescence. Acting as internal regulators, auxinic compounds coordinate responses their ever-changing environment.

Tooth development is a multi-stage and multi-step process involving fate determination morphogenetic patterning events, epithelial-mesenchymal interactions, cell proliferation, differentiation, migration. Animal model studies have shown that YAP TAZ, effectors of the Hippo pathway, critical function in tooth morphogenesis. However, TAZ has not been well documented its specific roles morphogenes...
