A Model For Development Built By Biologists
2012-08-31 12:40:24

Caltech biologists create the first predictive computational model of gene networks that control the development of sea-urchin embryos As an animal develops from an embryo, its cells take diverse paths, eventually forming different body parts–muscles, bones, heart. In order for each cell to know what to do during development, it follows a genetic blueprint, which consists of complex webs of interacting genes called gene regulatory networks. Biologists at the California Institute...

Caltech researchers discover a genomic control system that regulates gut formation in sea-urchin embryos For all animals, development begins with the embryo. It is here that uniform cells divide and diversify, and blueprints are laid for future structures, like skeletal and digestive systems. Although biologists have known for some time that signaling processes"”messages that tell a cell to express certain genes so as to become certain parts of these structures"”exist at this...

A quartet of studies by researchers at the California Institute of Technology (Caltech) highlight a special feature on gene regulatory networks recently published in the Proceedings of the National Academy of Sciences (PNAS).The collection of papers, "Gene Networks in Development and Evolution Special Feature, Sackler Colloquium," was coedited by Caltech's Eric H. Davidson, the Norman Chandler Professor of Cell Biology. His coeditor was Michael Levine, professor of genetics, genomics and...
