Formation of the mouse cochlea: roles of Sonic hedgehog
Resumé
The formation of the mammalian cochlea is dependent on signalling from its surrounding tissues during embryogenesis. Using genetically engineered mutant mice and surgically manipulated chicken embryos, we demonstrated that Sonic hedgehog (Shh) secreted from the developing notochord and the floor plate is important for specification of ventral inner-ear structures that include the cochlear duct. Additionally, tissue-specific knockout of Shh in the developing spiral ganglion indicates that this source of Shh is required for mediating growth of the cochlear duct, timing of terminal mitosis of hair cell precursors, and subsequent differentiation of nascent hair cells along the cochlear duct.Referencer
