HONEYCOMB STRUCTURE, METHOD FOR PREPARING THE STRUCTURE, FILM AND CELL CULTURE BADE USING THE STRUCTURE

Document Type and Number:

Japanese Patent JP2001157574

Kind Code:

A

Abstract:

To provide a step when a base and/or a cell forms a three dimensional structure in culturing a cell.

A hydrophobic organic solvent solution of a polymer comprising 50-99% of a biodegradable polymer (polylactic acid) and 50-1% of amphiphatic polymer (Cap) is cast to a base at 50-95% relative humidity under atmospheric pressure. The organic solvent is gradually transpired and simultaneously condensed on the surface of the cast solution and minute water drops formed by the condensation are evaporated to give a honeycomb structure. The sheet or the cell culture base is obtained by using this honeycomb structure.
