We have demonstrated that for the establishment of cell polarity, stabilization and bundling of microtubule are essential and that molecules implicated in epithelial morphogenesis such as MID1 encoded by a causative gene of Opitz syndrome and its related protein MID2 play important role in the stabilization/bundling of microtubules. Thus we have been able to propose that this remodeling of microtubules allows the trafficking of secreted vesicles and cell polarity factors on the rail of bundled microtubules.

我们已经证明，为了建立细胞极性，微管的稳定和捆绑至关重要，并且与上皮形态发生有关的分子，例如由Opitz综合征的致病基因编码的MID1及其相关蛋白MID2在微管稳定/集合中起重要作用。因此，我们已经提出，微管的这种重塑允许在捆绑的微管导轨上运输分泌的囊泡和细胞极性因子。
