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 cel function or morphology. OBJECTIVE:To investigate the effects of isoflurane on the proliferation and differentiation of neural stem cels in the hippocampus of rats. METHODS:Neural stem cels from the hippocampus of neonatal Sprague-Dawley rats, aged 7 days, were induced and differentiated. Passage 3 cels 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 folowed by 2 hours of routine culture, anti-BrdU monoclonal antibody immunofluorescent staining was used to detect cel proliferation, and western blot assay to detect the expression of β3-tubulin and glial fibrilary acidic protein. RESULTS AND CONCLUSION:Compared with the control group, the number of BrdU positive cels in the isoflurane group reduced significantly, indicating that isoflurane inhibits the proliferation of neural stem cels. Compared with the control group, the expression of glial fibrilary 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 cels into astrocytes.
