传统的体外培养是有用的,以代表简单的神经元行为,然而,缺乏组织的结果在随机神经突蔓延。为了克服这个问题,控制SH-SY 5 Y细胞的方向性,利用光刻法将细胞排斥性阴离子刷聚(甲基丙烯酸3-磺丙酯钾)(PKSPMA)图案化为20,40,80和100 μm宽的轨道。这些数据验证了PKSPMA刷涂层用于SH-SY 5 Y细胞的长期培养的用途,以及提供了一种方法,通过该方法可以利用PKSPMA的精确沉积来实现对SH-SY 5 Y细胞的靶向控制。具体而言,PKSPMA刷状图案阻止细胞附着,使SH-SY 5 Y细胞仅在不同细胞密度(5000、10 000和15 000个细胞/cm 2)的无涂层玻璃(20、50、75和100 μm宽的间隙)上生长。这项研究证明了在体外实现细胞方向性的重要性,而这些简单的模型可以为研究复杂的神经元-神经元相互作用提供新的平台。
Conventional in vitro cultures are useful to represent simplistic neuronal behavior; however, the lack of organization results in random neurite spreading. To overcome this problem, control over the directionality of SH-SY5Y cells was attained, utilizing photolithography to pattern the cell-repulsive anionic brush poly(potassium 3-sulfopropyl methacrylate) (PKSPMA) into tracks of 20, 40, 80, and 100 μm width. These data validate the use of PKSPMA brush coatings for a long-term culture of the SH-SY5Y cells, as well as providing a methodology by which the precise deposition of PKSPMA can be utilized to achieve a targeted control over the SH-SY5Y cells. Specifically, the PKSPMA brush patterns prevented cell attachment, allowing the SH-SY5Y cells to grow only on noncoated glass (gaps of 20, 50, 75, and 100 μm width) at different cell densities (5000, 10 000, and 15 000 cells/cm2). This research demonstrates the importance of achieving cell directionality in vitro, while these simplistic models could provide new platforms to study complex neuron–neuron interactions.
