Including the new structure which this invention improves promotion of nervous tissue playback and healing playback etc of the organism soft organizational deficiency section, raminin and nervous growth factor (NGF) without jointly using, consists of the collagen and that, it offers the component for organization playback which becomes. The structure which consists of the collagen which relates to this invention has film multi tufted structures thin, differs with colloid, gel and fibrous. Because of that, when the new structure which consists of the collagen which relates to this invention is used for the component for organization playback, surprisingly, it is possible to improve the promotion of playback of body organization such as nervous tissue, subcutaneous organization, organization, biomembrane organization, adipose tissue, muscular organization, skin organization and gum organization etc under the mucous membrane, shortening and functional recovery in healing period. Furthermore, when nervous cause characteristic it uses for the patient whom it possesses painfully, that it is possible to disappear painfully.本発明は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。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。
