Title: Nanopore having cell adhesion and cell growth inhibitory effects, substrates having the same structure, and method for manufacturing the same
Inventor: HORADE MITSUHIRO
IPC: C12M3/00
Filed: 2019-03-26
Abstract: To provide a substrate with which selective control of cell adhesion regions and non-adhesion regions may be realized.SOLUTION: A substrate 300 includes a nanopore array structure 100 having cell adhesion and cell growth inhibitory effects. The nanopore array structure 100 includes a base 1 and a plurality of concave nanopores 3. A plurality of nanopores 3 are formed on the base 1. Due to the concave nanopore 3, when the nanopore array structure 100 and an object come into contact, the object actually comes into contact thereto on a limited section, but not its entire apparent surface. Under a microscale, a scale effect occurs in which the adhesive force is more dominant than gravity, and the adhesive force can be reduced by reducing a contact area. After adhering to a scaffold structure, adherent cells migrate by changing the stress fibers of the cells and the structure of pseudopodia. At this time, since the contact area is smaller than usual, the structure formation of cell stress fibers and pseudopodia is suppressed.SELECTED DRAWING: Figure 4
