Effect of GSKI on retention of MSCs in the lungs 14 days following LPS challenge in the LPS control and LPS+GSKI groups. (A) Immunofluorescent staining to detect MSC engraftment in lung tissues. White arrows indicate green fluorescent protein-positive cells; nuclei were stained blue with DAPI (magnification, ×200; scale bar, 20 µm). (B) All values are presented as the mean ± standard deviation (n=6–8 animals). *P<0.05. ARDS, acute respiratory distress syndrome; GSKI, glycogen synthase kinase-3β inhibitor; MSCs, mesenchymal stem cells.
