Abstract
Description
人体組織バンクから供給されて−70℃で冷凍保管していた羊膜組織(30mm×30mm)を室温で約30分間放置した後、羊膜に5Mウレアを5分間処理して羊膜の上皮細胞を除去した。上皮細胞が除去された羊膜を20mm×26mmスライドガラスにかぶせて、スライドガラスを35mm培養皿に入れ、堅固に固定させた。
角膜移植手術が終わった死体眼から輪部組織を採取するために、手術ツールを利用して輪部のサイズが約2mm×3mmになるように12断片に分離した後、周辺角膜と結膜を切開して除去した。その後、実施例1で製造した羊膜スライド支持体上に採取した輪部を載置し、37℃、CO2培養器で約12日間培養した。培養時に2〜3日間隔で培養培地を交換し、輪部組織由来上皮細胞板がスライド面積の85〜90%以上を占めるようになると、これを患者に移植することができるようにした。
輪部組織由来上皮細胞板内輪部幹細胞の比率を比較測定するために、羊膜スライド支持体およびトランスウェル(対照群)で90%以上成長した細胞にdispaseII溶液を2mg/mlで4℃で一晩処理した。微細なフォーセップを利用して羊膜から輪部組織由来上皮細胞板を分離して、1mlのtrypLEに入れ、5分間処理した後、1000rpmで5分間遠心分離して細胞沈殿物を得た。これをSHEM培養培地で懸濁し、JC−1 low比率とCFE測定のために細胞を計数して、6ウェルプレートに分注した。JC−1 low比率を測定するために、細胞を1.0×105個/mlの濃度で分注し、SHEM培養培地を利用して24時間培養した後、JC−1染色試薬を1時間処理して、FACSを利用してJC−1 low細胞であるサイドポピュレーション細胞の比率を測定した。一方、コロニーの形成を確認するために、細胞をCNT50培地(Cellntec)で14日間培養した後、コロニーの個数を計数してCFEを確認した。
従来、輪部組織を培養するのに一般的に使用されるSHEM(supplemented human epithelium media)培地には、CT(Cholera Toxin)およびFBSが含まれている。しかし、培養された輪部組織は、人体移植用に使用するためのものであるから、培養時に動物成分(FBS)と毒性(CT)成分を排除するために、下記表1に表示された培地組成で培養実験を行った。
多様な支持体に対する輪部幹細胞の比率を比較検定するために、対照群としてトランスウェル(TW)、PVDF膜に付着しない羊膜(w/o PVDF)、PVDF膜に付着した羊膜(with PVDF)、リングで固定された羊膜(with ring)と、本願発明のスライドガラスに付着した羊膜(with slide)に対して、培養5、7、9、12、14日目にそれぞれ細胞増殖の面積および輪部幹細胞の比率を確認した。
