本実験の中心的な焦点は、PVATデポからのAPCの単離、拡大、および脂肪生成誘発である。ここでは、表面マーカーCD34およびPDGFRαを発現する細胞の同定に基づいて、APCの単離のためのプロトコールを提示する。これらの表面タンパク質は、APC上で、高い増殖速度および様々な脂肪貯蔵庫14,15中の白色または褐色脂肪細胞に分化する可能性を伴って以前に同定された。これらの?...

脈管周囲脂肪組織（PVAT）は、血管に近接しているため、脈管機能1における主要なパラクリンシグナル伝達成分である。この脂肪組織の拡大は、存在する脂肪細胞前駆細胞（APC）の表現型に依存する2,3 。脂肪組織からの細胞の単離は、主要な脂肪細胞が壊れやすく、浮力があり、大きさの範囲があるため、困難である。特定の単離技術はまた、炎症性タンパク質合成を増加させ、脂肪生成遺伝子発現を減少させることによって細胞表現型および形態を変えることができ、細胞の完全性を維持するプロトコルの重要性を強調する。 初代細胞および特異的前脂肪細胞亜集団の培養は、インビボ増殖に対する還元主義的アプローチを提供し、同等の細胞遺伝的メイクアップ5を維持するが、これらの細胞の私は、老化や老化による劣化のために制限されています6 。皮下および大網デポーを含む様々な脂肪デポーからの前脂肪細胞もまた、特定の解剖学的部位から細胞を集めることの重要性を強調する増殖の差異7を示す。非PVAT白色脂肪細胞由来の前駆細胞は、以前の研究7,8,9において特徴付けられてきたが、PVAT APC表現型についてはあまり知られていない。 ここに記載された技術は、形態学、生存能力、および増殖および分化の可能性に最小限の影響を及ぼしながら、特異的および限定されたAPC集団の分析を可能にする。ビーズが細胞を変えずに溶解するので、磁気活性化細胞選別（MCS）は、培養などの下流の適用に適している。 MCSもまた経済的であり、一旦、抗体の欠点フローサイトメトリーアッセイの必要性は最小限に抑えられています。 PVAT前駆体を用いたインビトロ研究はまた、これらの初代細胞が有する可能性を垣間見ることができる。

expansion and adipogenesis induction of adipocyte progenitors from perivascular adipose tissue isolated by magnetic activated cell sorting

パラクラインシグナリングを介した血管機能の主要調節因子である血管周囲脂肪組織（PVAT）の拡大は、肥満時の高血圧の発症に直接関連する。肥大および過形成の程度は、デポの位置、性別、および存在する脂肪細胞前駆細胞（APC）表現型のタイプに依存する。過去10年間のAPCおよび前脂肪細胞分離のために使用された技術は、個々の細胞が特定の細胞表面マーカーに基づいて同定され得る正確さを大幅に改善した。しかしながら、APCおよび脂肪細胞の単離は、特にインタクトな細胞を細胞培養適用のために保持しなければならない場合、細胞の脆弱性のために困難であり得る。 磁気活性化細胞選別（ MCS）は、脂肪組織の重量単位あたりより多くの生存APCを単離する方法を提供する。 MCSによって回収されたAPCは、インビトロプロトコールでプレア成長因子カクテルを使用してそれらを脂肪細胞に分化させ、細胞によって保持された多分性および脂肪生成能の分析を可能にする。この実験は、拡張中の心臓血管疾患の発症において重要な役割を果たす大動脈および腸間膜のPVATデポーに焦点を当てた。これらのプロトコルは、定義されたAPC集団を分離し、拡大し、そして区別するための方法を記載する。このMCSプロトコルは、最小限の設備またはトレーニングで細胞選別が必要なあらゆる実験で分離を使用することを可能にする。これらの技術は、細胞表面マーカーの存在に基づいて特定の細胞集団の機能性を決定するさらなる実験を助けることができる。

前脂肪細胞の増殖能力および脂肪細胞前駆体の脂肪生成能は、インビトロで維持される特性である11 。定量的DNAアッセイを用いてプレーティングした8,24,48および96時間後に、雄ラットのaPVAT、mPVAT、およびGONから単離したSVFおよびAPCのin vitro増殖を評価した。同じサイトのSVF細胞（ 図1 ）と比較して96時間の増殖が?...
