Caption (B) Vertebral columns of Wfikkn1tm1.1Sjl/Wfikkn1tm1.1Sjl Fsttm1Zuk/Fsttm1Zuk (Gasp2-/-; Fst-/-), Wfikkn1tm1.1Sjl/Wfikkn1tm1.1Sjl (Gasp2-/-), wild-type (wt), Gdf11tm1Sjl/Gdf11+ (Gdf11+/-) and Gdf11tm1Sjl/Gdf11tm1Sjl (Gdf11-/-) mice. Note the changes in the number of ribs. *Gasp2-/-; Fst-/- mice also had a reduced number of lumbar vertebrae from six to four, with extensive fusion of lumbar and sacral segments. (C) Cervical and anterior thoracic regions of Wfikkn1tm1.1Sjl/Wfikkn1tm1.1Sjl (Gasp2-/-), wild-type (wt) and Gdf11tm1Sjl/Gdf11tm1Sjl (Gdf11-/-) mice. Note the shift of the position of the anterior tuberculum (arrow) from C6 to C5 in Gasp2-/- mice and from C6 to C7 in Gdf11-/- mice. (D) Vertebrosternal ribs of Wfikkn1tm1.1Sjl/Wfikkn1tm1.1Sjl Fsttm1Zuk/Fsttm1Zuk (Gasp2-/-; Fst-/-), Wfikkn1tm1.1Sjl/Wfikkn1tm1.1Sjl Fsttm1Zuk/Fst+ (Gasp2-/-; Fst+/-), Gdf11tm1Sjl/Gdf11+ (Gdf11+/-), and Gdf11tm1Sjl/Gdf11tm1Sjl (Gdf11-/-) mice. Note changes in the number of attached ribs and additional cervical ribs (arrow). (E) Schematic representation of vertebral columns. Gdf11+/- and Gdf11-/- mice have anteriorly directed homeotic transformations of the axial skeleton. In contrast, mice lacking certain GDF-11 inhibitors (Gasp2-/- and Gasp2-/-;Fst-/-) have posteriorly directed transformations. Cervical (orange), thoracic (purple), and lumbar (sky blue) vertebrae, anterior tuberculi (small blue dots), ectopic ribs from a cervical vertebra (green curved lines), sternums (red curves), and ribs (blue lines) are color coded as indicated. The dashed lines indicate the normal positions of typical vertebral characteristics: 6 for the anterior tuberculum, 14 for the most posterior rib attached to the sternum, 20 for the most posterior thoracic vertebra, and 26 for the most posterior lumbar vertebra.
