The filling liquid supply source is connected to a portion of the circulation circuit between the first valve and the pump. After the concentrated cell suspension is stored in the reservoir, in a state where the valve is closed and the pump is driven, the filling liquid supply source starts supplying the filling liquid to the circulation circuit to push the cell suspension, which remains in a portion of the circulation circuit from the pump to the inlet port of the reservoir, to flow toward the reservoir by the filling liquid.

Dual Circulation Microphysiological System
20220162534 · 2022-05-26 ·

A microfluidic cell culture system is provided. The system includes a dual circulation arrangement for providing the cell culture with culture medium (and, optionally, selected compounds for study). The dual circulation arrangement permits culture conditions to be readily modified for different phases of cell culture. In particular, a first circulation route can be used to circulate a relatively high volume of medium, thereby allowing a low cell number to medium volume ratio, and a second circulation route can be used to circulate a relatively low volume of medium, thereby allowing a high cell number to medium volume ratio. The first circulation is optimised for a pre-culture period, before test compounds are added, and the second circulation is optimised for the test phase, providing a high cell number to medium ratio while preserving function during the test period.
