A new step in drawing a biomolecular guide for developing cells

Treating cancer is an illustrative example on why the understanding of fundamental biological processes one of the most fundamental challenges in life sciences. Major leaps have already been made on the genetic and biological basis of this disorder. Using massive parallel techniques like gene expression arrays have given us elaborate descriptions of the differences between, organs, healthy and diseased tissue and other models. Unfortunately, these descriptive approaches have yet to provide us with a clear explanation on how the biology of the cell is organized. Nevertheless many epiphanic glimpses into the organization of biological mechanisms have been published revealing a stunning complexity based on simple instructions. One such significant insight was the link between embryogenesis and cancer (1).
