image: Experimental patterns of Bmp2, Sox9 and Wnt (From top to bottom). On the right a schema of the Bmp-Sox9-Wnt Turing network that controls the periodic pattern of fingers and toes during development. This image relates to a paper that appeared in the Aug. 1, 2014, issue of Science, published by AAAS. The paper, by J. Raspopovic at the Centre for Genomic Regulation (CRG) in Barcelona, Spain, and colleagues was titled, "Digit patterning is controlled by a Bmp-Sox9-Wnt Turing network modulated by morphogen gradients." view more
