Description
特許文献1(中国特許出願公開第101020899号明細書)に記載の方法によって、分離された生物活性を有する分離体皮膚組織細胞を得て、これを乳酸リンゲル液(Lactated Ringers solution)に半時間浸す。その後、香丹注射液、田七注射液、紅花注射液、当帰注射液、50%のブドウ糖注射液と組換え体ヒト上皮成長因子を順次添加した。ここで上記各物質を順次添加する毎に均一にかき回し操作を行い、半時間経過してから他の一つの物質を添加する。全部の上記成分物質を添加して、皮膚組織細胞の集合体を得た。香丹注射液、田七注射液、紅花注射液、当帰注射液、50%のブドウ糖注射液は、市販されている中国四川昇和製薬會社の製品である。組換え体ヒト上皮成長因子は、中国成都美兮生物技術有限會社の製品である。
実施例1の方法によって本発明の皮膚組織細胞の集合体を獲得し、獲得した皮膚組織細胞の集合体と、特許文献1(中国特許出願公開第101020899号明細書)に記載の方法で獲得した皮膚組織細胞の集合体とで、瘢痕患者に対して瘢痕修復を実行し、修復効果を比較して評価した。
