一种细胞培养微芯片的制作及应用

Fabrication and Application of a Novel Cell Culture Microchip

细胞培养是细胞研究的基础,微系统技术的发展给细胞培养提供了新的方法。在微系统平台上进行细胞研究,能够充分利用微流体和微结构的性质,对细胞进行操控,在细胞生物学、组织工程学、药物筛选等领域有广泛应用。文中介绍了一种利用SU-8负性光刻胶模具制作双层细胞培养微芯片的方法,该芯片通过狭缝将细胞培养区和微通道区隔离,既保证细胞培养区域的相对独立,又可以利用微流体的特性调节细胞外基质的性质,给基于微芯片进行细胞研究提供了一种新的平台。

In this article, a cell culture microchip was fabricated on the SU-8 mold based on polymer-MEMS process. In the microchip, the cell culture area was separated with microchannel by a microgap, which kept the cell culture area independent, but also regulated the micro-environment of extracellular matrix by the microfluidic flow. The cell culture microchip provided a new platform for cell research.
