HEC-1-B Cells

Categories: Reproductive system cancer cell lines Description: The HEC-1-B cell line is a human endometrial adenocarcinoma cell line. This line has been utilized extensively in biomedical research related to the study of endometrial cancer, hormone responses, and cancer pharmacology. The cells are known to express estrogen and progesterone receptors, making them a valuable model for studying hormone-related dynamics in endometrial cancer progression and treatment. These cells have been used to investigate the molecular mechanisms of cancer cell proliferation, differentiation, and response to hormonal and chemotherapeutic treatments. In terms of morphology, HEC-1-B cells typically exhibit an epithelial-like shape and grow in a monolayer. They are characterized by their high capacity for in vitro proliferation. Genetic studies have revealed several chromosomal alterations which are thought to contribute to the cancerous phenotype of these cells. Research using the HEC-1-B cell line has contributed to a deeper understanding of endometrial carcinogenesis and offers a robust system for testing potential therapeutic agents. This cell line is also commonly employed in studies focusing on cancer cell invasion and metastasis, providing insights into the cellular behaviors that underpin these processes. Organism: Human Tissue: Uterus, endometrium Disease: Endometrial adenocarcinoma Synonyms: Hec-1-B, HEC-1B, Hec-1b, EC1-B, HEC1B, Hec1B Age: 71 years Gender: Female Ethnicity: Asian Morphology: Epithelial Growth Properties: Adherent Citation: HEC-1-B (Cytion catalog number 305095) Biosafety Level: 1 Ncbi_ Taxid: 9606.0 Cellosaurus Accession: CVCL_0294 Antigen Expression: Blood Type B, Rh+ Tumorigenic: Yes Culture Medium: EMEM (MEM Eagle), w: 2 mM L-Glutamine, w: 2.2 g/L NaHCO3, w: EBSS (Cytion article number 820100a) Supplements: Supplement the medium with 10% FBS and 1% NEAA Dissociation Reagent: Accutase Subculturing: Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium. Fluid Renewal: 2 to 3 times per week Freeze Medium: As a cryopreservation medium, use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress. Thawing And Culturing Cells: 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. Sterility: 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. Safety Precautions: 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.
