The inner ear, which contains sensory organs specialized for hearing and balance, develops from an ectodermal placode that invaginates lateral to hindbrain rhombomeres (r) 5-6 to form the otic vesicle. Under the influence of signals from intra- and extraotic sources, the vesicle is molecularly patterned and undergoes morphogenesis and cell-type(More)
Fibroblast growth factors play important roles in inner ear development. Previous studies showed that mouse Fgf16 is expressed asymmetrically during the otic cup and vesicle stages of development, suggesting roles in regulating or responding to anteroposterior axial cues. Here, we studied otic Fgf16 expression throughout embryonic development and found(More)
The inner ear, which mediates hearing and equilibrium, develops from an ectodermal placode located adjacent to the developing hindbrain. Induction of the placode and its subsequent morphogenesis and differentiation into the inner ear epithelium and its sensory neurons, involves signalling interactions within and between otic and non-otic tissues.

OBJECTIVE To determine the role of patched receptor (Ptc)-1 in mediating pulsatile flow-induced changes in vascular smooth muscle cell growth and vascular remodeling. APPROACH AND RESULTS In vitro, human coronary arterial smooth muscle cells were exposed to normal or pathological low pulsatile flow conditions for 24 hours using a perfused transcapillary(More)
OBJECTIVES To determine the efficacy of perivascular delivery of Notch 1 siRNA in preventing injury-induced arterial remodeling. METHODS AND RESULTS Carotid artery ligation was performed to induce arterial remodeling. After 14 days, morphometric analysis confirmed increased vSMC growth and subsequent media thickening and neointimal formation. Laser(More)
The axial tissues of the vertebrate embryo is a term that refers collectively to the floor plate (a cell population that lies at the ven-tral floor of the neural tube) and the notochord (which is a meso-dermal rod of cells located immediately ventral to the floor plate). The notochord and floor plate both secrete the morphogen signal Sonic Hedgehog (Shh)(More)
