Here a microfluidic chip with 'micro-dam' and 'micro-gap' has been designed and fabricated. It could isolate different cells and flow of medium in each region. It was found that the chip could realize the cells co-culture and patterning of human lung adenocarcinoma cell (A549), human embryonic lung fibroblast (HLF-1) and human endothelial cells (HUVECs), respectively. After 72 hours of culture, three kinds of cells grew well. It provided a developing technical platform for cell related research.
