Description
好ましくは、歯根の凹型に、細胞を懸濁したゲルを流し込み、次いで、ゲルが凝固する前に歯根を当該凹型に入れ、歯根表面にゲルを凝固させることにより細胞を播種する。
さらに好ましくは、ゲルはフィブリンゲルである。
好ましくは、凝固したゲルの厚みは20μm〜1mmである。
好ましくは、細胞は、歯根膜細胞、歯肉線維芽細胞、歯乳頭細胞、歯髄細胞または間葉系幹細胞である。
本発明による細胞の播種方法は、歯根の凹型を用いて、生体より採取した歯根または人工歯根の表面に、ゲルに懸濁した細胞を播種することを特徴とする。
以下の実施例により本発明をさらに具体的に説明するが、本発明は実施例によって限定されるものではない。
2 凹型
3 ヒト歯牙
4 ヒト歯根膜細胞を懸濁したフィブリンゲル
