| abstract |
A bioreactor for cultivating living cells in a liquid medium. In one embodiment of the present invention, the bioreactor has a first substrate (140) having a first surface (140a) and an opposite second surface (140b), defining a chamber(101) therebetween for receiving cells and the liquid medium. The bioreactor further has a barrier (104) dividing the chamber (101) into a first subchamber (102) and a second subchamber (103), wherein the barrier (104) has a porosity to allow the first subchamber 102) and the second subchamber (103) in fluid communication and allow at least one predetermined type of cells to permeate between the first subchamber (102) and the second subchamber (103) in fluid communication and allow at least one predetermined type of cells to permeate between the first subchamber (102) and the second subchamber (103). |
