新型Gd基T2造影剂的制备和应用
A New Gd-Based T2-Weighted Magnetic Resonance Imaging Contrast Agent: Preparation and Application in Stem Cell Imaging
摘要
Abstract
We synthesized TPP-Lys(Acp-DOTA-Gd)-COOH (Gd-DOTA-TPP) as a novel T2-weighted MRI contrast agent, and used it to label human mesenchymal stem cells (hMSCs) via electroporation. hMSCs labeled with Gd-DOTA-TPP presented a rather dark T2-weighted image at a cellular Gd content of about 9×109 Gd/cell. The labeled cells were syringe-injected into a mouse brain with defined cell numbers followed by T2-weighted MRI on an 11.7 T system, which yield an in vivo imaging sensitivity of about 103 cells.关键词
