Abstract
OBJECTIVE
To explore the effects of lipopolysaccharide (LPS) pretreatment on endotoxin tolerance of human umbilical cord mesenchymal stem cells (hUCMSCs) and its possible mechanism.
METHODS
hUCMSCs (1×10(4) cells/well) were exposed to 0, 0.1, 1.0, 10.0, 20.0, 30.0, 40.0, 50.0 µg/ml LPS for 24 h respectively. And the cell viability of hUCMSCs was detected… (More)
