Abstract

Intrauterine inflammation affects fetal development of the nervous system and may cause prenatal brain injury in offspring. Previously, neural stem cells have been extensively used as a therapeutic choice for nervous system diseases. Recently, the therapeutic ability of conditioned medium, harvested from cultured stem cells, has captured the attention of researchers in the field. Our study aimed to compare the therapeutic effect of neural stem cells (NSCs) or NSC-conditioned medium (NSC-CM) after prenatal brain injury. The animal model was induced by intraperitoneal injection of lipopolysaccharide into the pregnant mice and NSCs or NSC-CM were transplanted into the lateral ventricle of embryos in treatment groups. Inflammation and apoptosis were evaluated postpartum in offspring via measuring the expression of NLRP3 gene and protein, the expression and the activity of caspase-3, and the expression of pro-inflammatory cytokines by real-time PCR, immunohistochemistry, western blotting, ELISA, and colorimetric assay kit. A rotarod test was performed for motor function evaluation. Data showed that although NSC-CM fought against the inflammation and apoptosis and improved the motor function, NSCs acted more efficiently. In conclusion, the results of our study contend that NSCs have a better therapeutic effect than CM in prenatal brain injury.
