LIVER BIOPSY ON CHIP

AIMS LIVER BIOPSY ON CHIPLiver Biopsy

→ Increase biopsies viability in long term culture liver biopsy
→ Imaging and biochemical quantification of drug effect
→ Interface blood vessel/hepatocyte
→ DILI assessment based on the biochemical marker and morphometric read-out

FEATURES LIVER Biopsy

→ Temperature: 37°CLIVER BIOPSY ON CHIP
→ Gas: normoxia & hypoxia
→ Perfusion mode: pulse
→ Culture unit: 24 well multi-well & 2 custom microfluidic chip

RESULTS

→ Metabolic functions maintain over 7 days (CYP450, EROD…)
→ First morphometric criteria acquired: necrosis assessment (edges, center)
→ Biochemical markers and DILI assessment ongoingLIVER BIOPSY ON CHIP

PERSPECTIVE

→ Going to super-resolution to image eventual effect of drugs on endothelial nanopores structures (supposed target of toxicity)
→ Going above 7 days to mimic chronic exposure (several plasmatic peaks patterns..)
