From: Intratracheal Delivery of CX3CL1-Expressing Mesenchymal Stem Cells to Multiple Lung Tumors
Tropism of MSCs for tumor cells in vivo. Lungs with or without metastases of LLC were removed 7 d after intratracheal injection of MSCs derived from GFP-transgenic mice. GFP-positive cells were detected with anti-GFP antibody. Lung tissues with (A, B, E, and F) or without pulmonary metastases (C and D) are shown. Left panels are lower magnification (100×); right panels are higher magnification (200×); arrows indicate the part at higher magnification. Panels C, D, E, and F are the lungs after MSC injection. Panels A and B are the lungs after PBS injection.
