Patent number: 11773357Abstract: A perfusion plate that can be combined with pillar plates containing cell layers is disclosed. The perfusion plate can have an inflow reservoir and an outflow reservoir connected by at least one channel, which fluidly connects the perfusion wells to the reservoirs for the flow of a fluid such as growth media. A perfusion plate can be part of an assembly containing a pillar plate, a lid, and a transparent bottom for visualizing cell growth in the perfusion wells. The perfusion-pillar plate assembly can facilitate perfusion-based tissue culture and tissue communication for high throughput, high-content, drug screening.Type: GrantFiled: October 23, 2020Date of Patent: October 3, 2023Assignee: Cleveland State UniversityInventor: Moo-Yeal Lee
