About the Cover

Cover Figure


Cover: The skeleton of a mouse embryo at E18.5. Loss of Hox9 paralogous function causes dramatic defects in rib cage development. Thirteen thoracic ribs attach to the sternum instead of the normal seven, along with four extra vertebrae with unattached ribs. Hox5, Hox6 and Hox9 paralogous mutants all show dramatic defects in axial patterning. See research article by McIntyre et al. on p. 2981 .
