Dlx5 regulates regional development of the branchial arches and sensory capsules.
We report the generation and analysis of mice homozygous for a targeted deletion of the Dlx5 homeobox gene. Dlx5 mutant mice have multiple defects in craniofacial structures, including their ears,Expand
Role of the Dlx homeobox genes in proximodistal patterning of the branchial arches: mutations of Dlx-1, Dlx-2, and Dlx-1 and -2 alter morphogenesis of proximal skeletal and soft tissue structures
The Dlx homeobox gene family is expressed in a complex pattern within the embryonic craniofacial ectoderm and ectomesenchyme. A previous study established that Dlx-2 is essential for development ofExpand
The Cranial Vascular System in Taeniolabidoid Multituberculate Mammals
Two skulls of Late Cretaceous multituberculates from Mongolia, Nemegtbaatar gobiensis and Chulsanbaatar vulgaris, were serially sectioned on a Jung microtome at thicknesses respectively of 25 and 20Expand

The middle ear in multituberculate mammals
Three almost complete incudes and two fragments of malleus are described and compared with those reported in the Paleocene Lambdopsalis and in non-multitubercltate mammals. In these Late CretaceousExpand
Truncation of the MLL gene in exon 5 by gene targeting leads to early preimplantation lethality of homozygous embryos
Summary: The mixed lineage leukemia gene (MLL) was originally identified through its involvement in reciprocal translocations in leukemias. MLL codes for a large multidomain protein and bearsExpand
The primitive course of the internal carotid artery in mammals.
In all recent mammals the internal carotid artery at the level of the auditory capsule is derived from the embryonic dorsal aorta. In adults of various groups, the artery lies in positions which areExpand
Evolutionary biology: Pelvic problems for mammals
So closely has a structure known as the epipubis been associated with marsupial mammals that it has become known as the 'marsupial bone'. The discovery of epipubic bones in fossil specimens that areExpand
Alisphenoid equivalents in placentals, marsupials, monotremes and fossils
The interpretation of the wall of the brain case between orbit and ear has important implications for mammalian phytogeny. The fossil mammalian groups morganucodonts, triconodonts andExpand
The pterygoid and ectopterygoid in mammals
SummaryA dorsal pterygoid element and a ventral ectopterygoid element can be recognised during the development of monotremes, marsupials and eutherian mammals. Their homology with the elements soExpand
