Research Abstract

初年度は造血幹細胞の冬眠とそれを支える機構に関してヒト骨髄細胞を対象として研究を行なう予定であった。しかし、Type II TGF受容体欠損マウスの造血幹細胞を解析したところSmadのリン酸化が低下しているとともに、長期骨髄再建能が有意に低下していることが明らかになったことから、マウスの骨髄ニッチにおけるTGF-βの重要性がより明確となり、計画を変更してこれについて集中して研究を行なった。TGF-βはLatency-associated protein(LAP),Latent TGF-β binding protein(LTBP),活性型TGF-βの3つの分子より構成される非活性型複合体として骨髄中の多くの細胞によって産生される。我々は非活性型複合体を分解して活性型TGF-βを遊離することができる場所がニッチであると仮定し、ArrayScanを利用しながら活性型TGF-βやIntegrinαv β 8などを手がかりに検索を進めた。その結果、骨髄中に存在するGFAP陽性、POタンパク陰性、MBP陰性のnon-myelinating Schwann細胞がTGF-βを活性化する能力を持つことが明らかとなった。実際、CD150、CD48、CD41、分化抗原マーカーなどを用いて解析したところ、23%の造血幹細胞がnon-myelinating Schwann細胞に近接して存在していた。non-myelinating Schwann細胞が造血幹細胞のニッチであることを機能的・直接的に証明するためlumbar sympathetic trunkを切断したところ、術後3日目には切断側のみに造血幹細胞の減少が認められ、術後7日目には正常側の骨髄と比して10%程度まで減少した。これらのデータは骨髄中のグリア細胞が造血幹細胞の冬眠を維持することによって骨髄造血を制御していることを示唆しており、造血系と神経系が成体ホメオスタシス維持に関与していることを示す画期的な証拠と考えられる。
