HNO41 Cells

The HNO41 cell line is derived from a hypopharyngeal squamous cell carcinoma, a type of head and neck squamous cell carcinoma (HNSCC). This cell line has been characterized by several chromosomal aberrations, including DNA copy number gains in chromosomal regions such as 3q23-qter, 5p, 7p, 7q21-q22, 8q22.2-qter, 9q22-qter, and 11q13. These regions are known to harbor oncogenes that contribute to tumor progression, making HNO41 a valuable model for studying the molecular mechanisms underlying hypopharyngeal cancer.

In addition to its genetic profile, HNO41 has been analyzed for its expression of angiogenic growth factors, which are critical in tumor development and metastasis. The cell line exhibits strong expression of vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF), among others. These factors are involved in promoting angiogenesis, the formation of new blood vessels, which is a key process in tumor growth and metastasis. The presence of these factors in HNO41 further supports its utility in research focused on understanding tumor angiogenesis and in evaluating anti-angiogenic therapies for HNSCC.

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

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.

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.

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

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.

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

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.

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

When planning to store a cryovial in liquid nitrogen for future thawing, it is mandatory to adhere to stringent safety measures. Appropriate protective gloves and clothing are essential, and the use of a face mask or safety goggles is required during the transfer of frozen samples to or from the liquid nitrogen tank. This is to mitigate the risk of injury from potential cryovial explosions upon removal, which can result in the projection of sharp fragments.
