Reduced ulna and radius in Hoxa9,10,11 −/−;Hoxd9,10,11 −/− mutants at E12.5. a–b wild type, note radius and ulna size. c–d Hoxa9,10,11 −/−;Hoxd9,10,11 −/−, smaller ulna and radius, with the ulna more severely reduced. Two sections of each are shown to give a more complete view of the malformations. Cartilage is visualized with Sox9 immunostain (red). Cell nuclei are visualized with DAPI stain (blue)
