A temperature responsive CT nanotracer, TRAuNPs, was developed, which exhibited improved hMSC labeling efficiency and prolonged intracellular retention time, thereby facilitating enhanced and long-term CT imaging tracking of hMSCs in IPF.
Identification of paracrine factors secreted by transplanted mesenchymal stem cells (MSCs) during the treatment of idiopathic pulmonary fibrosis (IPF) is essential for understanding the role of MSCs in the therapy....
