What is the significance of isolating hepatocytes?
Isolating hepatocytes is crucial for studying liver functions and diseases, as well as for drug testing and toxicology.
How does the collagenase perfusion method work?
The method involves cannulating liver blood vessels, perfusing with collagenase to digest tissue, and then isolating cells through centrifugation.
What are the applications of isolated hepatocytes?
Isolated hepatocytes can be used in research on liver regeneration, pharmacokinetics, and toxicology studies.
How is the viability of hepatocytes assessed?
Viability is assessed using the triam blue exclusion assay, which distinguishes live cells from dead ones.
Can this method be applied to other mammalian livers?
Yes, the modified collagenase perfusion procedure can be adapted for isolating hepatocytes from other mammalian species.
