该协议提供了一种在多隔室 (MC) 装置中从成年 Sprague Dawley 大鼠收获和培养外植背根神经节 (DRG) 的技术。
我们的研究旨在了解导致慢性肌肉骨骼疼痛的一些潜在机制,以便我们可以开发新的靶向治疗方法。因此,我们开发了慢性腰痛和神经元敏化的体外和体内模型。由于动物模型和人类受试者慢性疼痛表型之间的机制差异,目前在动物模型中起作用的体内疗法经常无法通过临床试验。
通过该模型的单独测试,慢性疼痛中存在的伤害感受器超敏反应有可能确定更有前途的人类慢性疼痛治疗方法。我们的方案清楚地展示了如何分离原代背根神经节,并在多室装置中培养它们。通过保持完整的原代背根神经节,我们维持天然支持细胞并在多室装置中培养它们,从而在神经元胞体和周围神经突之间实现解剖学相关的隔离。
该工具将有助于以更具生理和解剖学相关性的方式培养原代背根神经节,从而提高结果的翻译功效。具体来说,我们很高兴使用该系统来确定慢性疼痛中存在的伤害感受器超敏反应的新治疗方法。
