Long‐Term Cultures of Adult Mammalian Hepatocytes in Hollow Fibers as the Cellular Component of Extracorporeal (Hybrid) Liver Assist Devices

Abstract: A discussion of the treatment of liver insufficiency with extracorporeal (hybrid) liver assist devices (LADs) should address a definition of the types of liver failure susceptible to being treated by these devices as well as the modalities of in vivo and in vitro testing. Relevant to the first subject is the subject of pathogenesis of hepatic coma, which should be the target for the design of these LADs. Although this modality of therapy is new, it can be predicted that these devices will demand minimal safety… Show more

“…As an oversimplification, it can be argued that the better the blood compatibility of an artificial membrane, the worse its ability to support hepatocyte growth. There is quite a bit of confusion in the sub-ject, and in the past we have contributed to it by our work to explore the potential of hollow fibers to support hepatocyte growth (28)(29)(30). In fact, in the Circe device incorporated in the HepatASSIST 2000 (Circe Biomedical Inc., Lexington, MA, USA) currently in clinical trials, the hepatocytes are not grown but are placed in the devices just prior to their use with the patients.…”

Οι προκαταρκτικές κλινικές μελέτες που εξέτασαν τη χρησιμότητα του συστήματος αυτού σε ασθενείς με οξεία ηπατική ανεπάρκεια έδειξαν βελτίωση της νευρολογικής λειτουργίας, ελάττωση της ενδοκράνιας πίεσης και βελτίωση της πίεσης άρδευσης του εγκεφάλου.…”
