Abstract
Description
歯肉線維芽細胞を採取し、培養し、保存する手段は、当業者に周知であり、特に、Naveau et al.(2006)J.Periodontol.77:238−47に記載されている。
本明細書において意図されるように、「皮膚創傷」は、表皮及び/又は真皮のいずれかの破壊に関する。
本明細書において意図されるように、「適用すること」とは、創傷部位で晒された組織への歯肉線維芽細胞の収縮又は移植に関する。
角化細胞は、表皮を構成する、当業者に周知である表皮細胞である。
本明細書において意図されるように、創傷治癒を活性化する化合物は、皮膚の創傷治癒を促進し、加速し、又は改善する能力を有する任意の化合物に関する。このような化合物は、好ましくは、増殖因子及びサイトカインで構成される群から選択される。
歯肉線維芽細胞のサンプリング
組織試料の酵素処理の使用、または細胞培養基質上への接着のために配置された組織試料からの細胞の移動のいずれかによって生検から回収され、特に、Naveau et al.(2006)J.Periodontol.77:238−47に記載されている通りである。次に、線維芽細胞は、当業者に周知である技術に従って、適合した培養媒体上で増殖される。
真皮相当物のインビトロ再構築:組織リモデリング促進の評価
実施例1に従って得られる歯肉線維芽細胞は、Coulomb et al.(1998)Plast Reconstr.Surg.101:1891−1903に記載されるものなどの一般的な手法に従って、格子のコラーゲン原線維は、歯肉線維芽細胞によって収縮され、組織様構造、真皮相当物を形成するまで、三次元のコラーゲン格子の存在下で培養される。真皮相当物は、典型的には、約1〜2週間の培養後に得られる。
皮膚相当物のインビトロでの再構築:表皮化促進の評価
二層の皮膚相当物(表皮+真皮)は、実施例2に記載されるように構築された真皮相当物に、Coulomb et al(1986)Br.J.Dermatol.4:157−168に記載されるように得られる。
インビボでの創傷治癒:創縫合促進の評価
ラットは、3箇所の筋肉深部切断によって創傷を受け、そこに、それぞれ、対照の移植されていないコラーゲン格子、真皮線維芽細胞を用いて得られた真皮相当物、及び真皮線維芽細胞(実施例2)を用いて得られた真皮相当物が提供される。
予備の結果は、真皮線維芽細胞が新生真皮の形成を促進するための真皮線維芽細胞よりも効率が高いことを指示している。
引用された書誌的な参考文献は全て、参照により本明細書に援用される。
