JeKo-1

The JeKo-1 cell line is an established human mantle cell lymphoma (MCL) cell line derived from an adult patient. Mantle cell lymphoma is a type of non-Hodgkin lymphoma characterized by the overexpression of cyclin D1 due to the t(11;14)(q13;q32) chromosomal translocation. JeKo-1 cells exhibit this hallmark genetic aberration, making them a valuable model for studying the pathophysiology of MCL and testing therapeutic agents targeting the cyclin D1 pathway. These cells grow in suspension and possess a doubling time that facilitates robust experimental use in various high-throughput screening applications.

JeKo-1 cells are particularly useful in research focused on the molecular mechanisms of MCL, including the exploration of B-cell receptor (BCR) signaling pathways, apoptosis resistance, and drug resistance mechanisms. Additionally, this cell line serves as a model for studying the interaction between tumor cells and the microenvironment, especially in the context of lymphoid malignancies. Due to its well-characterized genetic background and consistent behavior in vitro, JeKo-1 is frequently utilized in the development and testing of novel anti-cancer compounds, particularly those aimed at overcoming chemoresistance in MCL.

37°C, 5% CO₂, humidified atmosphere.

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.
