[Abstract]  Successful neural circuit formation relies on the accurate navigation of axons towards their targets during development. Axons are guided by a combination of short-range and long-range, attractive and repulsive cues. The commissural axons of the developing spinal cord have provided an informative in vivo model for the identification of multiple axon guidance molecules and mechanisms. These axons extend ventrally from the dorsal spinal cord and cross the midline at the floor plate, before making a sharp rostral turn towards the head. This simple trajectory has facilitated the ... [摘要]  成功的神经电路形成依赖于在发展期间轴突朝向其靶标的精确导航。轴突由短程和长程,吸引和排斥线索的组合引导。发育中的脊髓的连合轴突提供了用于多轴突导向分子和机制的鉴定的信息的体内模型。这些轴突从背侧脊髓向腹侧延伸并在底板处穿过中线,然后朝向头部进行尖锐的嘴唇转向。这个简单的轨迹有助于许多轴突指导分子的识别,因为可以容易地识别作为遗传操作的结果的定型指导决定的干扰。开放书测定是评估脊柱连合轴突的轨迹的方法。脊髓被解剖出来​​,在屋顶板上打开并固定平。亲脂性荧光染料DiI的点状注射用于在显微镜和分析之前追踪连合轴突轨迹。
