PROBLEM TO BE SOLVED: To provide a tissue repair and/or regeneration promoting material which can be localized in and near a damaged area to be repaired and/or regenerated using a less invasive method, and which has a low possibility of causing damage due to compression and preferably has no possibility of causing damage due to compression when used in the damaged area.SOLUTION: A liquid tissue repair and/or regeneration promoting material, which is obtained by mixing a powder (or a granule) of a polymeric material and a cell, can be localized in and near a damaged area more easily using a less invasive method, and has a low possibility of causing damage and preferably has no possibility of causing damage when used in a target organ.COPYRIGHT: (C)2015,JPO&INPIT【課題】より低侵襲の方法を用いて、修復及び/又は再生すべき障害部位及びその近傍に局在させることができ、更に、障害部位に使用する際に、圧迫による障害を生じる可能性が低く、好ましくは圧迫による障害を生じない、組織修復及び/又は再生促進材を提供する。【解決手段】高分子材料の粉(又は粒)と細胞を混合して得られる液状の形態の組織修復及び/又は再生促進材は、より低侵襲の方法を用いて、より容易に、障害部位及びその近傍に局在させることが可能であり、更に、対象臓器に使用する際に、障害を生じる可能性は低く、好ましくは障害を生じる可能性がない。【選択図】なし
