A spheroid composite includes: a substrate including a cell-adhesive porous base material and plural hydrophilic regions and hydrophobic regions that are disposed on the porous base material and formed by curing a photosensitive composition, wherein the photosensitive composition includes a branched polyalkylene glycol derivative having three or more polyalkylene glycol groups, each having a polymerizable substituent at a terminal thereof, and a tri- or higher-valent linking group that binds to the polyalkylene glycol groups; and spheroids formed in the hydrophobic regions on the substrate, the plural spheroids having a uniform size. A spheroid-containing hydrogel, which includes a hydrogel and two or more spheroids having a uniform size with a diameter of from 70 µm to 400 µm that are disposed in the hydrogel in such a manner that the two or more spheroids do not contact each other, can favorably maintain the function of the plural spheroids contained within the hydrogel.
球状复合材料包括基底,包括细胞粘附性多孔基底材料,以及设置在多孔基底材料上并通过固化光敏组合物形成的多个亲水区域和疏水区域,其中光敏组合物包括支化聚亚烷基二醇衍生物,该衍生物具有三个或更多个聚亚烷基二醇基团,每个基团的末端都具有可聚合取代基,以及与聚亚烷基二醇基团结合的三价或更高价连接基团;以及在基底上的疏水区域形成的球形体,多个球形体大小一致。包含球形体的水凝胶包括水凝胶和两个或多个大小均匀、直径在 70 微米至 400 微米之间的球形体,这些球形体以两个或多个球形体不相互接触的方式放置在水凝胶中,可有效保持水凝胶中包含的多个球形体的功能。
