下丘脑-神经垂体系统(HNS)中的小鼠和大鼠大细胞神经元(MCNs)的器官型培养物已成为这种神经元表型的分子和生理研究的重要实验模型。然而,很难在这些培养物中长时间维持大量的MCN,特别是加压素MCN。在本文中,我们描述了使用的神经营养因子,白血病抑制因子(LIF)和睫状神经营养因子(CNTF),以拯救大鼠加压素(Avp)和催产素(Oxt)- MCNs从轴突切断诱导,程序性细胞死亡在体外。定量数据的LIF家族的神经营养因子对MCNs的生存在三个核,室旁核(PVN),视上核(SON),和附件(ACC)在小鼠和大鼠下丘脑核的疗效。
Organotypic cultures of mouse and rat magnocellular neurons (MCNs) in the hypothalamo-neurohypophysial system (HNS) have served as important experimental models for the molecular and physiological study of this neuronal phenotype. However, it has been difficult to maintain significant numbers of the MCNs, particularly vasopressin MCNs, in these cultures for long periods. In this paper, we describe the use of the neurotrophic factors, leukemia inhibiting factor (LIF) and ciliary neurotrophic factor (CNTF) to rescue rat vasopressin (Avp)- and oxytocin (Oxt) – MCNs from axotomy-induced, programmed cell death in vitro. Quantitative data are presented for the efficacy of the LIF family of neurotrophic factors on the survival of MCNs in three nuclei, the paraventricular (PVN), supraoptic (SON), and accessory (ACC) nuclei in the mouse and rat hypothalamus.
