Abstract: The present study aimed to investigate the regulatory effects of different concentrations of Loganin on the proliferation, survival, and differentiation of neural stem cells (NSCs) and its related molecular mechanisms. NSCs were isolated and cultured from the brain of adult mouse. The effects of Loganin on the proliferation, survival, and differentiation of NSCs were determined using different concentrations of Loganin.The results showed that the number and diameter of adult mouse NSCs significantly increased compared with those of control mouse after culturing in medium and high concentrations of Loganin for 5 days and 7 days (P<0.05). Medium and high concentrations of Loganin could promote the mitosis of NSCs. Low-dose Loganin treatment significantly promoted the differentiation of NSCs (P<0.01) and increased the number and proportion of neurons and astrocytes (P<0.01). However, medium and high concentrations of Loganin inhibited the differentiation of NSCs (P<0.05). Furthermore, high concentrations of Loganin reduced the number of neurons (P<0.05). These results suggest that a high concentration of Loganin could promote the survival of NSCs and enhance their proliferative ability by promoting the mitosis of NSCs. On the other hand, a low concentration of Loganin could promote the differentiation of NSCs and is beneficial for neurogenesis and oligodendrocyte regeneration. These results lay the theoretical and experimental foundation for research on NSCs for the treatment of central nervous system diseases.

Key words: Loganin, neural stem cells, proliferation, survival, differentiation, neurogenesis
