This could be due to the toxicity of the test compound. Here are other potential causes and recommendations:

-Sub-optimal culture medium: Use Williams Medium E with Plating and Incubation Supplement Packs; refer to our plating protocol
-Hepatocyte lot not characterized as plateable: Check lot specifications to ensure it is qualified for plating
-Cells were cultured for too long: In general, plateable cryopreserved hepatocytes should not be cultured for more than five days

First of all, we recommend comparing results to those reported on our lot-specific characterization specification sheet (human cells) and also referring to our enzyme induction protocol. Here are other potential causes and recommendations:

-Sub-optimal monolayer confluency: Please see our recommendations for 'I have a sub-optimal monolayer confluency for my hepatocytes. What should I do?'
-Poor monolayer integrity: Please see our recommendations for 'With my hepatocytes, I’m seeing rounding up of the cells, cellular debris, and/or holes in the monolayer, indicating dying cells. What should I do?'
-Inappropriate positive control: Check positive control to ensure suitability
-Incorrect concentration of positive control: Use the correct concentration of positive control

Please see the following causes and recommendations:

-Hepatocyte lot not transporter-qualified: Check lot specifications to ensure it is transporter-qualified
-Sub-optimal culture medium: Use Williams Medium E with Plating and Incubation Supplement Packs; refer to our plating protocol
-Not enough time for bile canaliculi to form: In general, at least 4-5 days in culture is required for bile canalicular network formation

Please see the following causes and recommendations:

-Hepatocyte lot not characterized as plateable: Check lot specifications to ensure it is qualified for plating
-Sub-optimal culture medium: Use Williams Medium E with Plating and Incubation Supplement Packs; refer to our plating protocol
-Cells were cultured for too long: In general, plateable cryopreserved hepatocytes should not be cultured for more than five days
