Abstract:

BACKGROUND: Isoflurane is an anesthesia drug that has a certain effect on the nervous system. It possibly causes neurologic disorders through impacting nerve stem cell function or morphology.
OBJECTIVE: To investigate the effects of isoflurane on the proliferation and differentiation of neural stem cells in the hippocampus of rats.
METHODS: Neural stem cells from the hippocampus of neonatal Sprague-Dawley rats, aged 7 days, were induced and differentiated. Passage 3 cells were obtained and divided into two groups: isoflurane group (a mixture gas of 2.8% isoflurane, 5% CO2 and 95% O2) and control group (a mixture of 5% CO2 and 95% O2). After  intervention of 6 hours followed by 2 hours of routine culture, anti-BrdU monoclonal antibody immunofluorescent staining was used to detect cell proliferation, and western blot assay to detect the expression of β3-tubulin and glial fibrillary acidic protein.
RESULTS AND CONCLUSION: Compared with the control group, the number of BrdU positive cells in the isoflurane group reduced significantly, indicating that isoflurane inhibits the proliferation of neural stem cells. Compared with the control group, the expression of glial fibrillary acidic protein in the isoflurane group up-regulated, but the expression of β3-tubulin had no changes, indicating isoflurane promotes the differentiation of neural stem cells into astrocytes.
