CCD-18Lu

The CCD-18Lu cell line is derived from normal lung fibroblasts of a human adult. These cells were established from the lung tissue of a male patient and are commonly used as a model for studying the behavior of normal human lung fibroblasts. The CCD-18Lu cell line exhibits typical fibroblast morphology, characterized by spindle-shaped cells that grow adherently in culture and form a monolayer.

Researchers utilize CCD-18Lu cells in various studies related to pulmonary biology, including investigations into lung development, repair, and fibrosis. These cells are instrumental in understanding the mechanisms underlying normal lung function and the response of lung fibroblasts to different environmental stimuli, such as cytokines, growth factors, and extracellular matrix components. Additionally, CCD-18Lu cells are employed in studies examining the effects of various drugs and compounds on lung fibroblast proliferation, differentiation, and collagen production.

In cancer research, CCD-18Lu cells serve as a control or reference cell line to compare with lung cancer cell lines, helping to identify specific molecular and cellular alterations associated with lung cancer progression. By providing insights into the behavior of normal lung fibroblasts, the CCD-18Lu cell line contributes to the development of therapeutic strategies for treating lung diseases, including fibrosis and cancer.

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.

At Cytion, we stand behind the quality and viability of our products. We guarantee that our cells will be viable at the start of culture for 60 days after shipment from our facilities. We assure that all materials conform to the specifications described in the Certificate of Analysis and/or Product Sheet.
