What are hepatocyte-like cells?
Hepatocyte-like cells are cells derived from pluripotent stem cells that exhibit characteristics similar to liver cells.
Why is ROCK inhibitor used in this protocol?
ROCK inhibitor enhances cell survival and attachment during the initial seeding process.
How long does the differentiation process take?
The differentiation process typically takes around 18 days, with specific media changes at designated intervals.
What markers are used to confirm hepatocyte-like cell identity?
Markers such as HNF4 alpha, Albumin, and AFP are used to confirm the identity of hepatocyte-like cells.
Can this method be scaled for larger productions?
Yes, the semi-automated approach allows for scaling up to produce multiple plates simultaneously.
What applications can hepatocyte-like cells be used for?
They can be used for disease modeling, drug screening, and studying liver biology.
