Turing’s Biological Philosophy: Morphogenesis, Mechanisms and Organicism

The Death of Nature and the Rebirth of Gaia: Organicism, the Mechanical Philosophy, and Feminized Nature

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...

Mechanisms of Morphogenesis

Forming an epithelium requires a mechanism for generating and maintaining a well-ordered array of cells. Now, two groups have uncovered a surprising strategy fororganizingcellswithinanepitheliumandcounteractingovercrowding. Marinari et al. (2012) and Eisenhoffer et al. (2012) show that cells are stochastically extruded fromdenselypacked regionsofgrowing tissues.Although active extrusionofapopto...

The Emergence of Subtle Organicism

Western science rests on the philosophical foundation of materialist monism, according to which only physical matter exists and therefore only physical matter can be known. Furthermore, matter is known to us only through the sense organs or indirectly through instruments. Consequently valid knowledge can only be derived from a logical interpretation of sensory experience. Materialist monism (he...

Tube Morphogenesis Making and Shaping Biological Tubes

Many organs are composed of epithelial tubes that transport vital fluids. Such tubular organs develop in many different ways and generate tubes of widely varying sizes and structures, but always with the apical epithelial surface lining the lumen. We describe recent progress in several diverse cell culture and genetic models of tube morphogenesis, which suggest apical membrane biogenesis, vesic...
