Abstract:

BACKGROUND: Neural stem cells have the potential to differentiate into neurons and glial cells to replace the injured brain cells, so as to achieve the purpose of repairing nerve injury.
OBJECTIVE: To observe the neuronal differentiation ability of cell subsets with stem cell characteristics in the adult rat meningeal tissues.
METHODS: Under anesthesia, the meningeal tissues were obtained from adult Sprague-Dawley rats to make cell suspension followed by inoculation and subculture. Then, the Nestin immunofluorescence staining was performed. The third generation cells were cultured in vitro with complete culture medium containing trichostatin A. After 7 days of induction, western blot assay was used to detect the expression of NF-200 and BM88 proteins in neural cells.
RESULTS AND CONCLUSION: At 24 hours of culture, some spherical cells were suspended and some cells adherent. In addition, some spherical cells scattered gradually formed the clone spheres, and the growth rate decreased with the increasing volume. The positive expression of Nestin was detected by immunocytochemistry staining, and the cell nucleus was stained blue by Hoechst staining. BM88 and NF-200 proteins were all expressed at 7 days of neural induction. These findings indicate that the cell subsets with stem cell characteristics in the adult rat meningeal tissues can differentiate into neurons after in vitro induction.
