Genetic analysis of the development and evolution of the vertebrate head is at a primitive stage. Many homeo box genes, including the Distal-less family, are potential regulators of head development. To determine the function of Dlx-2, we generated a null mutation in mice using gene targeting. In homozygous mutants, differentiation within the forebrain is abnormal and the fate of a subset of cranial neural crest cells is respecified. The latter causes abnormal morphogenesis of the skeletal…

Craniofacial, vestibular and bone defects in mice lacking the Distal-less-related gene Dlx5.
The defects observed in Dlx5-/- mutant animals suggest multiple and independent roles of this gene in the patterning of the branchial arches, in the morphogenesis of the vestibular organ and in osteoblast differentiation.
Cre-mediated gene inactivation demonstrates that FGF8 is required for cell survival and patterning of the first branchial arch.
Genetic evidence is obtained that FGF8 has a dual function in BA1: it promotes mesenchymal cell survival and induces a developmental program required for BA1 morphogenesis, and the data suggest that the BA1 primordium is specified into a large proximal region that is controlled by F GF8, and a small distal region that depends on other signaling molecules for its outgrowth and patterning.
Dlx5 regulates regional development of the branchial arches and sensory capsules.
The distinct focal defects within the branchial arches of the Dl1, Dlx2 and DlX5 mutants, along with the nested expression of their RNAs, support a model in which these genes have both redundant and unique functions in the regulation of regional patterning of the craniofacial ectomesenchyme.
Mammalian Dlx homeobox gene control of craniofacial and inner ear morphogenesis
Interestingly, none of the individual murine DlX gene mutations to date have resulted in limb defects, suggesting a potentially significant developmental overlap of Dlx activity in this embryonic structure.
Specification and morphogenesis of the zebrafish larval head skeleton.
It is hypothesize that Endothelin-1 also is an upstream organizer of the patterns of cellular interactions during cartilage morphogenesis, and infer that different signal transduction pathways pattern cartilage development along these three separate axes.

The complementary genetic approaches in humans, mice and fish reveal networks of genes that specify the complex morphology of the head skeleton along a relatively simple set of coordinates.
Posterior axis formation requires Dlx5/Dlx6 expression at the neural plate border
It is shown that Dlx5/6 expression is required during vertebrate posterior axis formation during posterior neurulation of zebrafish and mouse and might help to gather a better understanding of human congenital NTDs etiology.
Craniofacial Development and the Evolution of the Vertebrates: the Old Problems on a New Background
A modern version of the germ-layer theory is defined in terms of the conserved differentiation of cell lineages, which is again questioned from the vantage of evolutionary developmental biology.
Skull and cerebellar phenotypes in Dlx 2 over-expressed mice
The Wnt1Cre::iZEG-Dlx2 mice might be an ideal model as to explore better therapeutic methods for genetic craniofacial and cerebellar defects and malformations.


Multiple developmental defects in Engrailed-1 mutant mice: an early mid-hindbrain deletion and patterning defects in forelimbs and sternum.
The results of these studies suggest a cell autonomous role for En-1 in generation and/or survival of mid-hindbrain precursor cells and also a non-cell autonomous role in signalling normal development of the limbs and possibly sternum.
Regionally restricted developmental defects resulting from targeted disruption of the mouse homeobox gene hox-1.5
Gene targeting in mouse embryo-derived stem cells has been used to disrupt the homeobox gene hox-1.5, and homozygotes are athymic, aparathyroid, have reduced thyroid and submaxillary tissue and exhibit a wide range of throat abnormalities.
Subtle cerebellar phenotype in mice homozygous for a targeted deletion of the En-2 homeobox.
The two mouse genes, En-1 and En-2, that are homologs of the Drosophila segmentation gene engrailed, show overlapping spatially restricted patterns of expression in the neural tube during
Developmental defects of the ear, cranial nerves and hindbrain resulting from targeted disruption of the mouse homeobox geneHox-#150;1.6
Gene targeting in mouse embryo-derived stem cells has been used to generate mice with a disruption in the homeobox gene Hox-1.6, causing profound defects in the formation of the external, middle and inner ears as well as in specific hindbrain nuclei, and in cranial nerves and ganglia.
