Description
1−1.トロンビンによるエクソソーム分泌誘導
ヒト臍帯血由来間葉系幹細胞(3×105個)を60mmの培養皿(orange scientific cat# 4450200)に分注した後、1週間培養した。培養皿に細胞が飽和増殖したことを確認した後、50unit/mlのトロンビン(REYON Pharmaceutical.Co.,LTD)が希釈されている血清フリー培養培地(MEM alpha media)に交替し、さらに6時間培養して、トロンビン処理された幹細胞を収得した。
前記実施例1−1で収得した幹細胞及びエクソソームがトロンビン処理により成長因子やIL−6のような抗炎症サイトカインなどの発現が増加したかを確認した。
妊娠後、18.5日が経過したSDラットの下腹部を切開して、子宮から胎児を取り出した後、前脳を用心深く摘出した。摘出された脳組織から大脳皮質の部分だけを用心深く分離した後、ピペットを利用して単一細胞で分離して、神経細胞培養液に入れて培養をする。培養後10日以後に、「グルコースが添加されていない培地を入れた後、1%低酸素条件(oxygne,glucose deprivation;OGD)」下に60分間露出させることによって、新生児HIEのin vitro modelを構築した。
前記実施例2で構築した新生児HIEのin vitro modelに、前記実施例1で収得したトロンビン処理幹細胞を処理した後、MTTアッセイを通じて神経細胞の生存率を測定した。
前記実施例2で構築した新生児HIEのin vitro modelに、前記実施例1で収得したトロンビン処理幹細胞由来のエクソソームを処理した後、MTTアッセイを通じて神経細胞の生存率を測定した。
動物モデルを利用してトロンビン処理幹細胞のHIEの治療活性を確認するために、下記のように実験を進めた。
(1)NC:正常対照群
(2)HIE+S:病気対照群(病気誘導後にsaline処理)
(3)HIE+H+WJ:HIE誘導後に低体温療法(Hypothermia)治療後、トロンビン非処理幹細胞処理
(4)HIE+H+Th.WJ:HIE誘導後に低体温療法(Hypothermia)治療後、トロンビン処理幹細胞処理
