Abstract
Description
従来、細胞の生着を促進する方法として、いくつかの方法が開示されている。例えば、特表2000−500327号公報には、精子を含む試料をアラビノース、ガラクトース、及び/又はヘキスロン酸を含有する多糖を含む溶液と接触させて、精子回収の際の精子の受精の可能性を高める方法について開示されている。また、特開平8−27011号公報には、IgA産生促進効果を有するビフィドバクテリウム属の菌体を有効成分とする妊娠動物用の胎児定着増強剤を用いて、胎児の発育異常と脱落防止を図り、胎児の定着を安定化する方法が開示されている。更に、特表2009−517078号公報には、骨髄移植(BMT)等において、細胞生着能を高めるために、細胞集団を、所定量のニコチンアミドで処理する方法について開示されている。しかしながら、これらの方法は、いずれも、上記のような、魚類の分離生殖細胞の生殖細胞系列への分化誘導方法における移植後の生殖細胞の宿主生殖腺への生着能の向上に適用できるものではない。
