Abstract
【解決手段】生体適合性のある網目状マトリックスに培養真皮細胞および培養表皮細胞を接種する工程、および前記接種したマトリックスを、培養皮膚デバイスを形成するために十分な条件下で、インキュベートする工程を実行する。
【選択図】なし
Description
コラーゲン(6.42mg/ml)を酢酸(0.01M〜1.0M)に、通常は16時間まで予め可溶化させることによりコラーゲン分散液を調製し、その後この分散液を4℃で保存する。炭水化物を加える場合には、次いでコンドロイチン-6-硫酸などのグリコサミノグリカン(GAG)との共沈物を調製することができる。コンドロイチン-6-硫酸(3.45mg/ml)を酢酸(0.01M〜3.0M)に加える。
炭水化物を含むまたは含まないタンパク質含有流体を調製してマトリックスを形成する。予備的ステップとして、凍結乾燥機を予め約-35℃から約-50℃に冷却する。一実施形態では、約-45℃に少なくとも4時間予め冷却してある95%エタノールを含む高密度ポリエチレン(HDPE)容器中で、凍結浴を準備する。しかし、制御された速度で熱を除去してマトリックスを凍結させるのに十分な温度の低下が約4時間までの時間枠内で起こる任意の型の装置または構成を使用することができる。例えば、約2時間以内に約4℃から約-40℃までの温度の低下、または約4時間以内に約4℃から約-75℃までの温度低下をもたらすように時間および温度を制御することができる。
すべての溶液は0.22μmフィルターで滅菌濾過し、すべての手順は当業者に公知の無菌手技を用いて実施する。
デバイスの外科的移植に先立って、微生物汚染を最少にし、血管供給を最高にすることによって創傷の準備を行う。これらの条件は通常、早期(すなわち熱傷後1週間未満)に接線方向に生存している基底まで焼痂を切開し、切開した創傷を死体同種皮膚移植片または皮膚代替物(すなわち、Integra Artificial Skin(商標))で一時的に保護することで達成される。
