Abstract
Description
本発明は組織増大用途に有用な移植可能なコラーゲン組成物を提供する。本発明の移植可能なコラーゲン組成物は、様々な医学的および美容的用途で用いるのに適した、増加した持続性を有する。変動性の極めて小さいかまたはない、ならびに操作性、押出性および侵入性の向上した移植可能なコラーゲン組成物も提供される。
一つの態様において、本発明により、分子内または分子間の架橋を実質的に含まない出発コラーゲン材料が提供されることは、本発明の材料の利点である。このコラーゲンを、架橋剤または架橋結合を誘導するのに適した条件(例えば、グルテルアルデヒド、放射線など)に曝露し、持続性を促進させるのに十分であるが、しかし材料の取り扱いの簡便性を損なうことのない架橋度を有するコラーゲンをもたらすことができる。具体的には、内因性の分子間または分子内架橋を実質的に含まず、また例えば、化学剤の使用または放射線などの架橋条件への曝露によって後に架橋されるコラーゲンは、同じ条件下でその後に架橋される内因的に架橋されたコラーゲンよりも低い程度に架橋させることができる。
合成コラーゲンは、例えば、Vuorela et al. (1997) EMBO J 16:6702-6712およびNokelainen et al. (2001) Yeast 18:797-806 (これらの文献はその全体が参照により本明細書に組み入れられる)に記述されている公知の方法に下記のように修正を加えた方法を用いて製造された。
それぞれ分子間および分子内の架橋を実質的に含まない合成ヒトIII型コラーゲンおよび合成ヒトI型コラーゲンに及ぼすコラゲナーゼの影響を調べた。マトリックスメタロプロテイナーゼ(MMP)は、コラゲナーゼとも呼ばれ、三重らせんのコラーゲンを切断できる酵素である。MMP-I (コラゲナーゼ1、線維芽細胞コラゲナーゼ)もMMP-8 (コラゲナーゼ2、好中球コラゲナーゼ)も三重らせんのI型、II型、およびIII型コラーゲンを切断する。
移植された合成ヒトI型コラーゲンおよび合成ヒトIII型コラーゲンのインビボでの持続性を以下のように調べた。移植の前日にWistar系ラット(Charles River Laboratories, Inc.)を剪毛し、注入部位の8 cm×6 cmに印を付けた。10 mM HCl中の3 mg/mLの濃度の精製コラーゲン調製物を1/10容量の0.2 M NaPO4, pH 11と混合した。コラーゲン原線維を4℃で15分間10,000×gでの遠心分離によって回収し、35 mg/mlのコラーゲン濃度でPBSに再懸濁し、リドカインを3 mg/mlの終濃度まで加えた。
