- Details on test system:
- RECONSTRUCTED HUMAN EPIDERMIS (RHE) TISSUE
- Model used: EPISKIN Skin Irritation Test 42 hours using human epidermis skin constructs supplied by SkinEthic Laboratories, Lyon, France
- Tissue batch number(s): 12-EKIN-009
- The model consists of normal, human-derived epidermal keratinocytes which have been seeded on a dermal substitute consisting of a collagen type 1 matrix coated with type IV collagen. After 13 days in culture a multilayered, highly differentiated model of the human epidermis with a functional multi-layered stratum corneum has formed. The epidermis surface area supplied was 0.38 cm². The EPISKIN kits include assay medium, maintenance medium, 12 well plates and the tissues which are shipped on nutritive agar.
- On receipt, the kit contents were checked and the inserts with tissues on agarose were stored at room temperature until use. The kit was used within the expiry date indicated by the supplier (expiry date: 5 March 2012). The maintenance medium was pre-warmed to 37º C. The tissues were removed from the agar and placed into wells of 12 well plates containing 2 mL pre-warmed maintenance medium per well. The tissues were incubated for a minimum of 24 hours at 37 ± 2°C in a humidified atmosphere of 5% CO2 in air.
TEMPERATURE USED FOR TEST SYSTEM
- Temperature used during treatment / exposure: room temperature
- Temperature of post-treatment incubation (if applicable): 37 ± 2°C
REMOVAL OF TEST MATERIAL AND CONTROLS
- After 15 ± 0.5 minutes, each tissue was rinsed with 25 mL sterile Dulbeccos Phosphate Buffered Saline (DPBS) to remove residual test substance. Inserts were then blotted on absorbent paper to remove remaining DPBS. Each insert was then transferred to a well containing 2 mL maintenance medium and incubated for 42 ± 1 hour at 37 ± 2°C in a humidified atmosphere of 5% CO2 in air.
MTT DYE USED TO MEASURE TISSUE VIABILITY AFTER TREATMENT / EXPOSURE
- The MTT reducing capability of the test substance, JNJ-38970191-AAA, was investigated by mixing 10 ± 2 mg of the test substance with 2 mL of 0.3 mg/mL MTT solution in duplicate.After 42 ± 1 hour, each insert was transferred to a well containing 2 mL of 0.3 mg/mL MTT and incubated for 3 hours ± 5 minutes at 37 ± 2°C in a humidified atmosphere of 5% CO2 in air.
- A control of 10 μL of distilled water, mixed with 2 mL of 0.3 mg/mL MTT solution was also included in duplicate.
- At the end of 3 hours ± 5 minutes, the triplicate inserts were blotted on absorbent paper. The epidermis was removed from the insert using a biopsy punch, the epidermis separated from the collagen matrix using forceps and both parts placed in a micro tube.
- When all tissues had been punched, the tissues were vortexed with 500 μL of acidic isopropanol (0.04 N HCl final concentration).
- The tissues were extracted by storing at 2-8 ºC, protected from light, for 70 hours.
- After formazan extraction, duplicate 200 μL aliquots of the extractant from each micro tube were pipetted into the wells of flat-bottomed 96-well plates. The extractant was mixed by vortexing prior to taking the aliquots. The absorbance was read at 540 nm, with six wells containing acidified isopropanol (0.04 N HCl final concentration) as a blank.
