Abstrakt:	The eardrum is an important structural component for hearing, but it is delicate and subject to traumatic injury and disease. Healing mechanisms are activated after injury but sometimes healing fails and chronic perforations develop, requiring surgical intervention. To model the wound healing responses we established a simple method for isolating keratinocytes and progenitors from individual eardrums. The central region of the eardrum contains epidermal proliferative centers that produce keratinocytes which migrate to cover the eardrum surface. We dissected out the central region and explanted it to the plastic membrane of a culture well insert. Epidermal cells grew from the explant onto the surface of the insert membrane. The cells could be serially harvested and passaged for continuous culture and characterization. Magnetic immunoseparation methods were used to enrich for epithelial cells with stem cell-like characteristics. Proliferation and migration in vitro was demonstrated, and the cells were shown suitable for tissue engineering applications.
