SUBSTRATE FOR CONTROLLING MOVEMENT DIRECTION OF ANIMAL CELLS, AND CELL IDENTIFICATION METHOD AND CELL SEPARATION METHOD WHICH USE SAID SUBSTRATE

摘要

The present invention provides a substrate for controlling a movement direction of animal cells, said substrate being characterized in that: a surface of the substrate is provided with a plurality of groove sections; the groove sections are each formed from a bottom section, and opposing wall sections; the opposing wall sections which form the groove sections are provided with a plurality of columnar protrusions; apexes of the columnar protrusions are each formed facing a point between apexes of two columnar protrusions formed on the opposing wall section, and face the same direction.
