ABSTRACT
<p><b>OBJECTIVE</b>To observe the regulatory effects of psoralen, oleanolic acid, and stilbene glucoside, three active components of psoralea fruit, glossy privet fruit and tuber fleeceflower root respectively, on Aβ25-35induced self-renewal and neuron-like differentiation of neural stem cells (NSCs).</p><p><b>METHODS</b>Embryonic NSCs werein vitro isolated and cultured from Kunming mice of 14-day pregnancy, and randomly divided into the control group, the Aβ25-35 group, the Aβ25-35 +psoralen group, the Aβ25-35 +oleanolic acid group, and the Aβ25-35 + stilbene glucoside group. The intervention concentration of Aβ25-35 was 25 µmol/L, and the intervention concentration of three active components of Chinese medicine was 10(-7)mol/L. The effect of three active components of Chinese medicine on the proliferation of NSCs was observed by counting method. The protein expression of Tubulin was observed by Western blot and immunofluorescence. The ratio of Tubulin+/DAPI was caculated. Results Compared with the control group, the sperical morphology of NSCs was destroyed in the Aβ25-35 group, the counting of NSCs, the expression of Tubulin protein, and the ratio of Tubulin /DAPI all decreased (P <0.01, P <0.05). Compared with the Aβ25-35 group, the counting of NSCs, the expression of Tubulin protein, and the ratio of Tubulin + /DAPI all increased in the three Chinese medicine treated groups (P <0. 01, P <0. 05).</p><p><b>CONCLUSIONS</b>25 µmol/L Aβ25-35 could inhibit self-renewal and neuron-like differentiating of NSCs. But psoralen, oleanolic acid, and stilbene glucoside could promote self-renewal of NSCs and neuron-like differentiation.</p>
