Quantitative analysis of labelled cells uptake in different organs, in lipopolysaccharide (LPS) and naive groups

Organ	Standard uptake values mean
	1 hour post intravenous cells injection		5 hour post intravenous cells injection
	LPS	Naive	LPS	Naive
Lung	8.0±3.8	7.45	6.4±2.7	4.3
Liver	2.2±0.8	1.7	1.9±0.5	0.6
Kidney	2.7±0.6	3.6	2.8±0.1	2
Brain	3.0±1.3	6.6	3.2±0.5	5.5

Labelled cells showed systemic distribution with an important retention in the lungs that persisted after 5 hours. Retention of cells was notably higher in the injured lung, compared with naive lung. Data are expressed as mean±SD.
