targeting of deep brain structures with microinjections for delivery of drugs, viral vectors, or cell transplants

脳実質へMicroinjectionsは薬物、ウイルスベクターまたは細胞移植を実現する重要な手続きです。注射針は、その軌道の間に生成される脳の病変だけでなく、脳が小さいだけでなく、時には複数の注射が必要な場合には特に、マウスの脳内の主要な関心事である。ここでは、大幅に脳の損傷を軽減し、齧歯類の脳に正確なターゲティングが可能な50μmの内腔を持つガラスキャピラリー針を製造する方法を示しています。このメソッドは、少量の配信が可能になります（20〜100 NLから）、出血のリスクを軽減し、脳実質への薬剤の受動拡散を最小限に抑えます。キャピラリーガラス管の異なるサイズを使用して、または針の内腔を変更することにより、物質や細胞のいくつかのタイプを注入することができます。ガラス毛細管とMicroinjectionsはインジェクション技術と小型げっ歯類での最小限の巻き添え被害をターゲティング脳深部に有意な改善を表しています。
