ABSTRACT
<p><b>OBJECTIVE</b>To investigate the feasibility of orientation-induced differentiation of rat bone marrow-derived mesenchymal stem cells (MSC) into cochlear hair cell-like cells in vitro.</p><p><b>METHODS</b>MSC were extracted, cultured and identified. The organ of Corti was isolated from post natal day 1-day 3 Sprague-Dawley rats. Then MSC were co-cultured with organ of Corti for 14 days in vitro. The expression of hair cell markers (myosin VIIa, math1 and calretinin) was detected by immunocytochemical analyses and by reverse transcription-polymerase chain reaction (RT-PCR).</p><p><b>RESULTS</b>The differentiated cells were immunopositive for myosin VIIa, calretinin and math1. And RT-PCR results indicated that these differentiated cells expressed hair cell markers Math1 and myosin VIIa.</p><p><b>CONCLUSIONS</b>MSC cultured in vitro could be successfully induced to differentiate into hair cell-like cells with hair cell molecular markers.</p>
