PROBLEM TO BE SOLVED: To provide a new structure comprising collagen for improving promotion of nerve tissue regeneration, cure and regeneration of a defective part of a soft biological tissue, or the like without using laminin or a nerve growth factor (NGF), and a member for tissue regeneration including the same.SOLUTION: The structure comprising collagen has a thin film multilocular structure and is different from a colloid form, a gel form, and a fibrous form. Therefore, when the new structure comprising collagen is used as the member for tissue regeneration, surprisingly, the promotion of regeneration, shortening of a treatment period, functional recovery, or the like of body tissues such as a nerve tissue, a subdermal tissue, a submucosal tissue, a biomembrane tissue, a fat tissue, a muscle tissue, a skin tissue, and a gingival tissue can be improved. Further, when the structure is used for a patient having neuropathic pain, the member is effective for the disappearance of the pain.COPYRIGHT: (C)2013,JPO&INPIT【課題】神経組織再生の促進、生体軟組織欠損部の治癒再生等を、ラミニンや神経増殖因子(NGF)を併用することなく向上させる、コラーゲンから成る新規構造体及びそれを含んで成る組織再生用部材を提供する。【解決手段】本発明に係るコラーゲンから成る構造体は、薄フィルム多房状構造を有し、コロイド状、ゲル状及び繊維状とも異なる。そのため、本発明に係るコラーゲンから成る新規な構造体を組織再生用部材に使用すると、驚くべきことに、神経組織、皮下組織、粘膜下組織、生体膜組織、脂肪組織、筋肉組織、皮膚組織、歯肉組織等の体組織の再生の促進、治癒期間の短縮、機能的回復等を、向上させることができる。更に、神経因性疼痛を有する患者に用いると、その疼痛を消失させることができる。【選択図】図1(a)
