PURPOSE OF REVIEW: Middle ear cholesteatoma is an epithelial lesion that expands into the middle ear, resulting in bone destruction. However, the pathogenesis of this has been unknown. The purpose of this review is to understand the role of keratinocyte growth factor (KGF) during epithelial stem and/or progenitor cell proliferation in middle ear cholesteatoma.
RECENT FINDINGS: Many researchers have investigated the molecular mechanism of middle ear cholesteatoma to establish a conservative treatment. Recently, some studies have focused on the stem cells of middle ear cholesteatoma and their detection, but the key molecules for stem cell formation were not shown.
SUMMARY: We established an animal model for middle ear cholesteatoma and are showing the results of our studies. KGF expression accelerates the proliferation of stem/progenitor cells through the induction of transcription factor p63 expression in the epithelium of the tympanic membrane and mucosal epithelium overlying the promontory of the cochlea and within the attic. This is typical in middle ear cholesteatoma. Moreover, the partial epithelial-mesenchymal transition under the p63 signaling pathway plays an essential role in epithelial cell growth in middle ear cholesteatoma formation. Understanding p63 expression following KGF expression and associated signaling events can improve therapeutic outcomes in patients with middle ear cholesteatoma.
