| Objective: To find a method to get the primary microglia with high purity and examine the expression of Notch
signal-associated molecules in microglia. Methods: Fetal mice cerebral cortex were used to isolate microglia by repetitively mechanical
shaking. The purity of isolated cells was identified by expression of CD11b and MHCII using flow cytometry. The expression of Notch
signal-associated molecules was examined by qPCR and gel electrophoresis. Results: 1.1×106 microglial cells with high purity (97.77%)
could be steadily produced from 5 fetal mice by repetitively mechanical shaking and the Notch signal-associated molecules were
examined in microglia. Conclusions: Primary microglia with high production and purity can be obtained by repetitively mechanical
shaking from fetal mice cerebral cortex, and the Notch signaling pathway is expressed in microglia. |
