この実施例の間葉系幹細胞をE2分泌細胞に誘導する誘導剤は、BMP4 50mg/L、BMP7 50mg/L、RA 8mg/L、レスベラトロール 6mg/L、イカリイン 6mg/L、ベンズアミド 4ug/L、塩化白金酸六水和物 6ug/L、エタノールアミン 4ug/L、EPO 5ug/L、VEGF 5ug/Lからなる。上記の成分を、質量濃度比でヒト間葉系幹細胞無血清培地(又はDMEM+10%FBS)に順次加え、よく混合し、濾過滅菌した。
ヒト脂肪間葉系幹細胞を例に、本発明の誘導剤による間葉系幹細胞からE2分泌細胞への分化誘導効果を説明すると、第3世代のヒト脂肪間葉系幹細胞を96ウェルプレートに1×104/cm2で播種し、細胞のコンフルエントが80%近くに達して増殖が活発になったときに分化誘導を行い、誘導条件の分類を表1に示した。
表1 誘導条件の分類
表2 異なる誘導剤の誘導効果の比較
表2の誘導結果から、本発明の誘導剤によるヒト脂肪間葉系幹細胞の誘導効率が最も高く、誘導された細胞からのE2分泌量が最も多いことがわかる。本発明の誘導剤を添加して2日後にE2が持続的に分泌され、分泌量が徐々に増加し、約5~7日目になると、E2の1日当たりの分泌量が最大になり、持続的に分泌することができる。
