Effects of leukemia inhibitory factor on endogenous neural stem cell proliferation and glycoprotein-130 expression in a mouse model of cerebral infarction

摘要

Leukemia inhibitory factor (LIF) has been shown to promote proliferation of endogenous neural stem cells. In this study, we treated mice with cerebral infarction using LIF to investigate whether the LIF receptor subunit glycoprotein (gp)130 is involved in neuroprotection. After LIF treatment, the motor function of model mice was significantly improved. Immunofluorescence histochemistry showed increased numbers of endogenous neural stem cells surrounding the infarct foci. Western blot analysis revealed that gp130 expression was significantly decreased surrounding the infarcted foci. Results demonstrated that LIF promoted the proliferation of endogenous neural stem cells by inhibiting gp130 protein expression.
