In vivo tracking of PKH26-labeled ERCs in CCl₄-induced ALI. Frozen section of lung, liver, spleen and kidney from mice of the untreated (as control) and ERC-treated groups 24 h after CCl₄ induction are showed. The strong red flourescent signals indicated that PKH26-positive cells were widely distributed in the hepatic lobules as scattered individual cells 24 h after ALI. Representative image showing PKH26-labeled ERCs were simultaneously observed in murine lung and spleen but not kidney. In addition, no obvious strong red flourescent signals were observed in the lung, liver, spleen or kidney from the untreated group (magnification ×100)
