| Popis: | We sought to establish a more efficient technique for induction of inner ear hair cell-like cells (HC-like cells) from embryonic stem cells (ES cells) by using a combination of two previously reported methods; ST2 stromal cell-conditioned medium, known to be favorable for HC-like cell induction (HIST2 method), and ES cells with transfer of the Math1 gene (Math1-ES cells). Math1-ES cells carrying Tet-inducible Math1 were cultured for 14 days with doxycycline in conditioned medium from cultures of ST2 stromal cells following formation of 4-day embryoid bodies (EBs). Although each of the previously introduced methods have been reported to induce approximately 20% HC-like cells and 10% HC-like cells in their respective populations in EB outgrowths at the end of the culture periods, the present combined method was able to generate approximately 30% HC-like cells expressing HC-related markers (myosin6, myosin7a, calretinin, α9AchR, Brn3c), which showed remarkable formation of stereocilia-like structures. Analysis of expressions of marker genes specific for cochlear (Lmod3, Emcn) and vestibular (Dnah5, Ptgds) cells indicated that our HIST2 method may lead to induction of cochlear- and vestibular-type cells. In addition, continuous Math1 induction by doxycycline without use of the HIST2 method preferentially induced cochlear markers with negligible effects on vestibular marker induction. |
