During the process of neurogenesis, the stem cell committed to the neuronal cell fate starts a series of molecular and morphological changes. The understanding of the physio-pathology of mechanisms controlling the molecular and morphological changes occurring during neuronal differentiation is fundamental to the development of effective therapies for many neurologic diseases. Unfortunately, our knowledge of the biological events occurring in the cell during neuronal differentiation is still poor. In this study, we focus preliminarily on the relevance of the cytoskeletal rearrangements, which earlier drive the morphology of the neuronal precursors, and later the migrating/mature neurons. In fact, neuritogenesis, neurite branching, outgrowth and retraction are seminal to the development of a fully functional nervous system. With this in mind, we highlight the importance of iPSC technology to study the processes of cytoskeletal-driven morphological changes during neuronal differentiation.
在神经发生过程中,致力于神经元细胞命运的干细胞开始一系列分子和形态学变化。了解控制神经元分化过程中发生的分子和形态学变化的机制的生理病理学,对于开发许多神经系统疾病的有效疗法至关重要。不幸的是,我们对神经元分化过程中细胞内发生的生物学事件的了解仍然很少。在本研究中,我们初步关注细胞骨架重排的相关性,其早期驱动神经元前体细胞的形态,后期驱动迁移/成熟神经元的形态。事实上,神经突发生、神经突分支、生长和回缩对于功能完备的神经系统的发育至关重要。考虑到这一点,我们强调诱导多能干细胞技术在研究神经元分化过程中细胞骨架驱动的形态变化过程中的重要性。
