When living tissue is lost due to trauma or inflammation, young tissue proliferates in the affected area. For example, when a skin wound heals, it appears as soft, red bud-like granules on the wound surface. It is made up of fibroblasts, capillaries, migratory cells, etc. It plays an important role in tissue regeneration and organization, and when that role is completed, it becomes a scar.

外傷により生体組織が欠損した際や,炎症などの際,その部分に増殖する若い組織。たとえば皮膚創傷の治癒(ちゆ)時に,創面に赤い芽のような柔らかい顆粒(かりゅう)として見られる。成分は繊維芽細胞,毛細血管,遊走細胞など。組織の再生,器質化などに際して重要な役割を果たし,その役割を終えると瘢痕(はんこん)となる。
