Abstract:

Cells exchange materials and information with each other through chemical signals, electronic exchange and direct contact, to regulate the growth and development of living organisms. Therefore, the research and regulation of cell-cell interaction are great significance in mechanism study of cell functions and the diagnosis and treatment of diseases. DNA nanostructures have the advantages of easy synthesis, easy modifi- cation, programmable design, and high biological safety, which are promising for cell-cell interactions research with simple operation, precise adjustment, and intelligent response. In this review, we summarized the DNA nanostructure-based cell assembly strategies such as oligonucleotide hybridization, receptor-ligand binding, and aptamer targeted recognition, then introduced some regulation means such as pH, metal ions, and DNA triggers. The discussion also focused on some applications of cell-cell interactions, including intercellular force measurement and imaging, in vitro tissue construction, cell-cell communication and cellular immunotherapy. Finally, the opportunity and challenge in this field were discussed.

Key words: DNA nanostructures, Cell-cell interaction, Cell assembly, Regulatory method
