ACHN

The ACHN cell line is derived from the malignant pleural effusion of a 22-year-old Caucasian male with widely metastatic renal adenocarcinoma. The cell line was established in November 1979, following direct seeding of the cancer cells into culture flasks containing Eagle's MEM with 10% FBS. Over a period of 150 days, the cells were maintained and passaged in vitro. Subsequently, the cells were inoculated subcutaneously into nude mice, where they formed palpable, locally invasive tumors within four weeks. This cell line is tumorigenic, as evidenced by its ability to induce tumors in 100% of nude mice (5/5) inoculated with 10⁷ cells, with tumors developing within 21 days.

ACHN cells are characterized by an adherent growth pattern and express specific isoenzymes, including G6PD (type B). This cell line is also noted for its response to human interferons and interferon inducers, making it particularly useful for antiproliferative studies. Both the original ACHN cells and those recovered from tumors in nude mice demonstrate growth inhibition in the presence of human interferons, highlighting their potential application in studies exploring the efficacy of interferon-based therapies for renal cancer.

The ACHN cell line is a valuable tool for cancer research, especially in the context of renal adenocarcinoma. It serves as an important model for studying tumorigenicity, metastatic behavior, and the effects of interferons on cancer cell proliferation. Its ability to form tumors in vivo and respond to interferon treatment provides a robust platform for developing and testing new therapeutic approaches targeting renal cell carcinoma.

1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods.

To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.

For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen.

Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage.
