Abstract
A bioartificial liver (BAL) based on human induced pluripotent stem cells (iPSCs)-derived hepatocyte-like cells (HLCs) and a multilayer porous bioreactor is provided. The plasma separation/retransfusion loop part includes a blood input pipe, an exhaust pipe spring clamp, a blood input peristaltic pump, a heparin pump, a plasma separation column, a first pressure monitor, and a heater. The cell reactor/plasma component exchange double-loop part includes a plasma input peristaltic pump, and a semipermeable membrane exchange column, a plasma exchange peristaltic pump, a red blood cell (RBC) pool, a membrane lung, a multilayer porous bioreactor, a second pressure monitor, and a third pressure monitor arranged in a 37° C. dedicated incubator. An outlet of the third pressure monitor and a blood cell outlet are connected to an inlet of the first pressure monitor, and then connected to the heater and a blood output pipe in sequence.
