The object of the present invention is to provide a cell supports three-dimensional, which is made of a material that is degraded in vivo and can be maintained in the absence of irregularities uniformly distributed cells. In accordance with the present invention, a cell support made of a porous material having the following characteristics: it is a porous material composed of a biodegradable material is provided. 99.99% less than 81% or more (b) average pore size:: (a) porosity 10~400μm And (c) having a pore between communicating hole, and (d) water absorption: less than 9900% 1000% or more本発明の目的は、細胞を均一に分布させムラのない状態で保持でき、かつ生体内で分解される素材で構成されている三次元の細胞支持体を提供することである。本発明によれば、生分解性材料から構成される多孔質体であって以下の特性を有する多孔質体からなる細胞支持体が提供される。(a)気孔率:81%以上99.99%以下(b)平均気孔サイズ:10~400μm(c)気孔間連通孔を有する、及び(d)吸水率:1000%以上9900%以下
