我们提出了一种手术植入稳定留置光学窗口的方案,用于小鼠胰腺的亚细胞分辨率成像,允许对健康和患病胰腺进行连续和纵向研究。

采用高分辨率的活体成像和改进的胰腺稳定方法,我们旨在增强对胰腺癌、胰腺炎和健康胰腺的生理动力学的理解。这种方法可以解决病理生理学理解方面的差距,从而有可能推进这些高危疾病的治疗策略。单细胞分辨率活体成像阐明了各种组织疾病进展的生理学和机制。

然而,由于胰腺的深度放置、顺应性和对运动伪影的易感性,胰腺面临着独特的挑战,阻碍了对良性和恶性疾病的有效观察。与之前的腹部成像窗口相比,我们的 SWIP 技术增强了小鼠胰腺的稳定性。设计独特的框架具有蚀刻线条,用于微型制图,从而在多个成像会话中实现一致的区域重新定位。

这有助于测量几天内的亚细胞动力学,提供有价值的见解。SWIP 方案能够对正常和患病状态下的小鼠胰腺进行稳定、高分辨率的单细胞活体成像。它特别有益于长时间的 3D 和 4D 成像,提供对细胞相互作用和疾病机制的见解。

该技术对于揭示胰腺生理学和病理学非常宝贵,可在体内可视化单个细胞及其环境。
