Abstract
Official abstract text for this publication.
An object of the present invention is to provide a three-dimensional cell support that is capable of uniformly distributing cells and retaining the cells in a state without nonuniformity and is made of a biodegradable material. The present invention provides a cell support consisting of a porous body made of a biodegradable material, the porous body having the following properties: (a) a porosity from 81% to 99.99%, (b) an average pore size of 10 to 400 μm, (c) having a hole interconnecting pores, and (d) a water absorption rate from 1000% to 9900%.
First claim
Opening claim text (preview).
The invention claimed is: 1. A cell support consisting of a porous body made of a biodegradable material, the porous body having the following properties: (a) a porosity from 81% to 99.99%, (b) an average pore size of 10 to 400 μm, (c) having a hole interconnecting pores, and (d) a water absorption rate from 1000% to 9900%, wherein the porous body is obtained by freezing and freeze-drying an aqueous solution which contains the biodegradable material.…
