生物反应器是可用于监测组织和细胞对候选药物的反应的系统。在创建骨软骨生物反应器的经验基础上,我们设计了一种新的3D打印系统,该系统允许在整个测试过程中光学访问细胞,以进行在线监测。由于3D打印的使用,可以在第三维中开发流体学,从而保持典型96孔板的单个孔的足迹。这种新的设计经过优化,以实现通过中央腔室的最大流体输送,这对应于最佳的营养或药物暴露。这种优化是通过改变生物反应器流体路径的每个尺寸来实现的。然后创建并测试优化药物暴露的物理模型。
Bioreactors are systems that can be used to monitor the response of tissues and cells to candidate drugs. Building on the experience developed in the creation of an osteochondral bioreactor, we have designed a new 3D printed system, which allows optical access to the cells throughout testing for in line monitoring. Because of the use of 3D printing, the fluidics could be developed in the third dimension, thus maintaining the footprint of a single well of a typical 96 well plate. This new design was optimized to achieve the maximum fluid transport through the central chamber, which corresponds to optimal nutrient or drug exposure. This optimization was achieved by altering each dimension of the bioreactor fluid path. A physical model for optimized drug exposure was then created and tested.
