Abstract
Description
本出願は、ここにそれらの全体を参考文献として合体させる2004年11月17日出願の仮出願第60/629,277号と、2005年9月26日出願の仮出願第60/720,917号との優先権を主張するものである。
本発明は、アガロースによって被覆された分泌細胞含有アガロースマクロビーズの質と量を改善するための方法に関する。これは下記のSeakem Goldアガロースの使用によって達成される。
図1はテストおよび対照動物の平均の1日の血糖値に関する情報を示している。
ここにその全部を参考文献として合体させる、2006年6月8日に第11/273,737号として公開された、ガズダ(Gazda)ほかの特許出願公開第2006/0121445号に記載の方法に従って、膵島を単離した。ただし、本発明はこの特定の単離方法に依存するものではないので、膵島の単離のためにその他の方法も可能であり、それらを使用してもよいことが銘記される。
上記で暗示したように、膵島の単離後、純度、生存率を含む様々なパラメーターを測定した。
この例と、これ以降の例とは、上述したようにして有用であるとして同定され単離された膵島がマクロビーズに使用可能であるか否かという問題を扱うものである。
この例は、ブタ膵島がイン・ヴィヴォで作用する能力を証明する実験について記載するものである。
この例は、異なるアガロースから製造されたアガロース−アガロース被覆ビーズが、移植動物においてどの程度、組織反応、すなわち、炎症、を引き起こすか、を測定するように構成された実験を記載するものである。
1=最小(10%以下の炎症)
2=軽度(10〜25%の炎症)
3=中度(25〜50%の炎症)
4=強度(50〜75%の炎症)
5=重度(75%以上の炎症)
これらの実験において、イン・ヴィトロで培養された膵島含有Seakem Goldアガロースマクロビーズが、対照(空)のマクロビーズと比較された。
以下の実験は、膵島をカプセル化するSeakem Goldアガロースが、長期間にわたってイン・ヴィトロで培養することが可能であり、それでも機能を維持することを示すものである。
本発明のビーズの強度を、FMC HGT(P)アガロースから形成され、それによって被覆されたビーズと比較するための実験を行った。
