|
• on the hindlimb digit 1 is present but small
|
|
• the proximal phalanx of hindlimb digit 1 is incomplete
|
|

| N | normal phenotype |
|
• deformed limbs at birth
|
|
• at E13.5, increased cell density is seen in the anterior and posterior limb bud mesenchyme corresponding to areas of transgene expression and cell proliferation in the posterior mesechyme is increased
• at E14.5 these excess cells aggregate and for an extra postaxial nubbin
|
|
• short and broad digits 1 and 5 on the fore and hind limbs
|
|
• short and broad digits 1 and 5 on the fore and hind limbs
|
|
• a post axial nubbin is present on the hindlimbs
• skeletal preparations show pre and post axial polydactyly
|
|
• after 2 weeks of age mice walk with the backside of their forelimbs facing down towards the ground
|
|
• very short limbs at birth
|
|
• the chondrogenic mesenchymal condensation of the ulna is larger resulting in formation of a short but large cartilage primordia of the ulna
|
|
• delayed endochondral bone formation is seen in the humerus, ulna, radius, and digits 1 and 5 at birth
|
|
• at E13.5, increased cell density is seen in the anterior and posterior limb bud mesenchyme corresponding to areas of transgene expression and cell proliferation in the posterior mesechyme is increased
• at E14.5 these excess cells aggregate and for an extra postaxial nubbin
