Research interests

My group uses the zebrafish as a model organism to study the development and function of vertebrate sensory systems. Our main focus is the inner ear, the organ of hearing and balance.

Development of the fish inner ear

Summary for the non-specialist

The inner ear is the organ that mediates our senses of hearing and balance. It consists of an intricate fluid-filled labyrinth housing a variety of extraordinarily sensitive sensory structures that respond to sound, movement and gravity.

For correct inner ear function it is essential that each of these components  form in exactly the right place in the embryo, as any abnormalities can lead to  deafness or balance disorders. Indeed, congenital deafness is an important clinical condition, affecting approximately one in every thousand children at birth.

Our aim is to understand how the inner ear develops in the embryo, and the mechanisms that ensure that the different cell types in the ear arise in the correct positions so that they can function accurately.

We use embryos of a small tropical fish, the zebrafish, in our research, as this fish is a superb model for the study of vertebrate inner ear development.

  • Cell membranes are labelled in green, and cell nuclei in red. 
  • Projections of epithelium grow into the centre of the vesicle to form the semicircular canal system.

Technical summary

Current projects in the Whitfield lab include:

  • Morphogenesis and patterning in the otic placode and vesicle

We are identifying pathways of gene activity that lead to correct axial patterning of the otic epithelium, together with establishment of the neurogenic, sensory and non-sensory domains in the developing ear. We have a long-standing interest in the roles that Hedgehog, Fgf and BMP signalling play in these processes.

Development of the vestibular system

The adult inner ear consists of three interconnected ducts of non-sensory epithelium—the semicircular canals—and various chambers containing sensory hair cells. We are examining zebrafish lines that develop with morphological defects of the semicircular canal system. We are using light-sheet microscopy to image semicircular canal formation in these lines, and automated tracking of adult fish to measure any balance deficits.

We are also interested in the formation of the otoliths, biomineralised ‘ear stones’ that sit over patches of sensory hair cells in the ear.  In the zebrafish ear, otoliths are initially tethered to the tips of kinocilia on the sensory hair cells. Later, they adhere to the sensory patch via the otolithic membrane.  We have recently identified two large glycoproteins involved in zebrafish otolith tethering and adhesion.

Modelling human deafness and vestibular disorders

Some of our zebrafish lines form models for a variety of human diseases, including Waardenburg-Shah syndrome, Branchio-Oto-Renal syndrome and DiGeorge syndrome.

Ototoxicity

A number of drugs used to treat human infections or cancer have ototoxic side effects: they damage sensory hair cells in the ear, leaving a patient with temporary or permanent hearing loss and vestibular impairment. We are using the lateral line of the zebrafish embryo as a screening tool to identify compounds that can protect hair cells from the ototoxic effects of drugs such as neomycin and cisplatin.
