人多能干细胞来源的皮层神经元
包含: 1 瓶冷冻 HPSC-CN(产品编号 #1750,1 mL,>1 × 10⁶ 个细胞/瓶)、 100 mL 神经元维持培养基(NMM,产品编号 #5951)、 2 mL 神经元维持补充剂(NMS 50X,产品编号 #5902)。
Cortical neurons are the principal excitatory projection neurons of the cerebral cortex and are central to information processing across sensory perception, cognition, and voluntary motor control through organized laminar microcircuits and long-range connectivity. During development and early life, cortical circuits undergo experience-dependent refinement (“critical period” plasticity), a process that strongly shapes synaptic connectivity and functional network maturation. Disruption of cortical development or circuit function has been implicated in numerous neurological and neuropsychiatric disorders, and in vitro human cortical neuron models provide high value for mechanistic discovery and drug screening. Human PSC-based corticogenesis platforms have demonstrated robust generation of cortical projection neuron subtypes in a temporal sequence and the formation of functional excitatory synapses and networks, supporting their use as scalable, standardized human model systems. Human Pluripotent Stem Cell-derived Cortical Neurons (HPSC-CN) from ScienCell Research Laboratories provide a robust, reliable, and consistent off-the-shelf option for human cortical neurons.
HPSC-CN are cryopreserved and delivered frozen. Each vial contains > 1 × 106 cells in 1 ml volume. HPSC-CN are characterized by immunofluorescence with antibodies specific to pan neuronal marker beta tubulin III (Tubb3) and cortical identity marker TBR1. HPSC-CN are negative for mycoplasma, bacteria, yeast, and fungi. HPSC-CN can be further cultured under the conditions provided by ScienCell Research Laboratories. HPSC-CN are not recommended for expansion since the cells do not proliferate in culture.
Recommended Medium
It is recommended to use Neuronal Maintenance Medium (NMM, Cat. #5951) for culturing HPSC-CN in vitro.
皮层神经元是大脑皮层中最主要的兴奋性投射神经元,在感觉信息处理、认知活动以及随意运动控制等方面发挥着关键作用。这些功能依赖于大脑皮层中有序的层状微回路结构以及远距离神经连接网络。在发育及生命早期阶段,皮层神经网络会经历一种依赖经验的精细化调节过程,即“关键期可塑性”(critical period plasticity),这一过程对突触连接的形成以及神经网络功能的成熟具有重要影响。
当皮层发育或神经环路功能发生异常时,可能与多种神经系统疾病和神经精神疾病的发生密切相关。因此,体外构建的人源皮层神经元模型在疾病机制研究和药物筛选方面具有重要价值。基于人多能干细胞(PSC)的皮层发育(corticogenesis)研究平台已经证明,可以按照发育的时间顺序稳定地产生多种皮层投射神经元亚型,并能够形成具有功能性的兴奋性突触和神经网络,从而成为一种可规模化、标准化的人源研究模型系统。
ScienCell Research Laboratories 提供的人多能干细胞来源的皮层神经元(Human Pluripotent Stem Cell-derived Cortical Neurons,HPSC-CN)是一种稳定、可靠且即用型(off-the-shelf)的人源皮层神经元产品。
HPSC-CN 以冷冻形式保存并运输。每瓶含 1 mL 细胞悬液,细胞数量 >1 × 10⁶ 个。
该细胞通过免疫荧光染色进行鉴定,检测标志物包括泛神经元标志物 β-微管蛋白III(β-tubulin III,Tubb3)以及皮层特异性标志物 TBR1。经检测,HPSC-CN 不含支原体、细菌、酵母及真菌污染。在 ScienCell Research Laboratories 推荐的培养条件下,这些细胞可以在体外继续培养。
需要注意的是,不建议对 HPSC-CN 进行扩增培养,因为该细胞在体外培养条件下不具备增殖能力。
