Co-culture comprised of cryopreserved primary feline hepatocytes cultured with cells of non-parenchymal, stromal type.
Example Metabolic Activity (nmoles/hr/106 cells)
| Substrate | Enzyme | Concentration (µM) | Day 1 | Day 4 | Day 8 |
| 7-Ethoxycoumarin | Phase I | 100 | 0.110 | 0.117 | 0.059 |
| 7-Hydroxycoumarin | Phase II | 100 | 5.060 | 3.950 | 4.277 |
| 7-Hydroxycoumarin | Phase II | 100 | 3.687 | 3.250 | 4.090 |
Culture Condition and Morphology
Cryopreserved primary feline hepatocytes were thawed and plated with HUREL PlatinumHeps™ Media supplemented with 10% serum and subsequently changed 24 hours post-seeding to HUREL PlatinumHeps™ Basal Media. CYP substrate concentrations are given in the table above along with metabolite formation recorded as nmoles/hr/106 cells. All incubations were carried out in triplicate on days 1, 4, and 8 upon cell delivery and incubated for 60 minutes. Reactions took place in a humidified incubator at 37°C, in 5% CO2. Collected supernatants were stored at -20°C until further LC/MS/MS analysis.
