Regenerative medical gel material

The present invention addresses the problem of providing a novel use whereby it is possible to suitably use a polymer gel material having a micron-sized porous structure. A regenerative medical gel material which contains a polymer gel in which hydrophilic polymer units are crosslinked with each other, and which is characterized in that: the polymer gel contains water as a solvent; and a three-dimensional grid structure having two regions, i.e., a first region in which the polymer units are densely present and a second region in which the polymer units are sparsely present, the size of the grid formed by the first region being 1-500 [mu] m. 本发明的课题在于提供一种能够适当应用具有微米级多孔体结构的高分子凝胶材料的新用途。一种再生医疗凝胶材料，其包含亲水性的聚合物单元相互交联而成的高分子凝胶，其特征在于，所述高分子凝胶含有作为溶剂的水，并具有具备所述聚合物单元密集存的第一区域及所述聚合物单元稀疏存在的第二区域这两个区域的三维网格结构，由所述第一区域构成的网格尺寸具有1～500μm的大小。
