项目摘要

ABSTRACT In the present proposal we will preserve, process and make available human ear tissue to inner ear basic researchers they will be able to compare with their animal models. The use of celloidin, microdissected tissue for immunohistochemical and quantitative techniques will be instrumental in driving basic animal inner ear research into the understanding of human ear pathology and has high potential for the development of effective drug therapies for restoring auditory and vestibular function. In Specific Aim 1) we will improve access for the auditory and vestibular research community to human ear tissues from temporal bone specimens. We will improve and promote timely procurement, preparing and processing of new specimens, and appropriate re- processing of archived specimens. We will distribute a limited number of well-prepared laboratory tissues to funded researchers who lack adequate access to facilities for human temporal bone preparation. We will also exploit use of the Registry for information about currently archived tissues and their access by the community, and promote collaborations between researchers seeking to validate animal models for human relevance. Specific Aim 2) We will optimize tissue preparation techniques. We will include molecular and cellular marking and visualization techniques that allow direct comparisons of fresh and archived human tissues with those from animal models. We will disseminate protocols for procurement, preservation and preparation of human ear tissues from temporal bones. By doing this we will encourage animal researchers to include human tissues into their analyses. Specific Aim 3) We will develop tools to exploit new technologies and methods to image and visualize human middle and inner ears in situ. Targets for imaging techniques will include soft cellular tissues, membranes and fluids, as well as hard bony tissues. Specific Aim 4) We will provide technical instruction with hands-on training will be available for investigators, technicians otolaryngology residents, medical school and graduate students interested in inner ear biology in the temporal bone processing techniques and skills needed for processing human ear tissues from temporal bones. The materials generate in this proposal will be extremely useful for the research in basis inner ear research field, in the USA and around the globe.
