PROBLEM TO BE SOLVED: To provide a sustained release material for tissue recovery, which allows for sustained release of a platelet derived component, having an excellent effect for facilitating tissue recovery.SOLUTION: The sustained release material for tissue recovery comprises: a biologically absorptive porous substrate formed of collagen and/or gelatin and a decomposition product of platelet supported by the biologically absorptive porous substrate. Preferably the decomposition product of platelet is concentrated. Preferably the biologically absorptive porous substrate is a composite of collagen and gelatin. In the case that a wide range of biological tissue is defected by wound or burn, the sustained release material for tissue recovery allows the defective part to be closed in an early stage.COPYRIGHT: (C)2014,JPO&INPIT【課題】血小板由来成分を徐放して優れた組織再生促進効果を発揮することができる徐放性組織再生材料の提供。【解決手段】コラーゲン及び/又はゼラチンからなる生体吸収性多孔質基材と、該生体吸収性多孔質基材に担持された血小板分解産物とからなる徐放性組織再生材料。該血小板分解産物は、濃縮されたものであることが好ましい。該生体吸収性多孔質基材は、コラーゲンとゼラチンとの複合体であることが好ましい。該徐放性組織再生材料は、生体組織が創傷や火傷によって広範囲に欠損した場合、早期に欠損部を閉鎖することができる。【選択図】なし
