Morphogenesis by symbiogenesis.
International microbiology : the official journal of the Spanish Society for Microbiology, 1998Here we review cases where initiation of morphogenesis, including the differentiation of specialized cells and tissues, has clearly evolved due to cyclical symbiont integration. For reasons of space, our examples are drawn chiefly from the plant, fungal and bacterial kingdoms.

On the morphogenesis of ulegyria
Acta Neuropathologica, 1981An 11 day old premature infant survived 8 days after a cardiac arrest. At necropsy, the infant's brain showed cortical arteries surrounded by cuffs of viable neurones, while the cortex between these arteries was necrotic. This appearance suggests that the pattern of nodules of neurones separated by radial bands of scar seen in ulegyria is probably the ...

Bioelectromagnetics in morphogenesis
Bioelectromagnetics, 2003AbstractUnderstanding the factors that allow biological systems to reliably self‐assemble consistent, highly complex, four dimensional patterns on many scales is crucial for the biomedicine of cancer, regeneration, and birth defects. The role of chemical signaling factors in controlling embryonic morphogenesis has been a central focus in modern ...

The Morphogenesis of Constitutionalism
2010Abstract This chapter argues that it is possible and necessary to talk about processes of constitutional morphogenesis. Morphogenesis is a socio-cultural cycle, whereby a given institutional and cultural structure gives rise — through cultural and structural interactions activated by societal actors — to new forms (morphogenesis) or ...

The flaviviruses consist of about 70 viruses that include some important pathogens that are responsible for a number of serious diseases, such as yellow fever, dengue fever, and various encephalitides (Porterfield, 1980; Shope, 1980). They are transmitted to humans by arthropod vectors, i.e., mosquitoes and ticks (Chamberlain, 1980) and are also called

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1977
The idea is now widely accepted that active cell locomotion is an important mechanism in many kinds of animal morphogenesis. The history of the idea suggests, however, that there was a peculiarly strong resistance to its acceptance. The resistance was not overtly expressed, but localized cell multiplication was nearly always preferred in explanations ...

The Morphogenesis of Poliovirus [PDF]
, 1972 Poliovirus is one of the simplest and most extensively studied animal viruses. Yet, in spite of the voluminous literature, many basic and important questions concerning its morphogenesis remain unanswered. For example, what mechanisms insure that the progeny virus retain the precise structural features of the infecting particle ? How does the viral RNA

Current Opinion in Genetics & Development, 2004
During starvation-induced Dictyostelium development, up to several hundred thousand amoeboid cells aggregate, differentiate and form a fruiting body. The chemotactic movement of the cells is guided by the rising phase of the outward propagating cAMP waves and results in directed periodic movement towards the aggregation centre.
