Description	The HT-29 cell line, derived from a Grade II human colorectal adenocarcinoma, represents a cornerstone research model in the study of human colon cancers. Derived from a primary tumor in a 44-year-old female in 1964, HT22 cells have been instrumental in advancing our understanding of the adhesion or invasion mechanisms of cancer cells. As a human adenocarcinoma cell line, HT-29 cells exhibit characteristics that closely mimic those of mature intestinal cells, such as enterocytes, underscoring their utility in exploring the dynamics of food digestion and nutrient bioavailability. HT-29 cells are sensitive to conventional colorectal cancer chemotherapies, including 5-fluorouracil and oxaliplatin. This sensitivity, coupled with their ability to express differentiation pathways under specific conditions, such as glucose deprivation or treatment with inducers like butyrate, makes them an invaluable model for investigating the molecular mechanisms underlying cell differentiation and cancer progression. Moreover, HT-29 cells have been utilized as a xenograft tumor model, providing a platform for in vivo studies that mimic the tumor's behavior in the human body. This application allows for the exploration of tumor growth, metastasis, and the efficacy of therapeutic agents in in vivo situations. In summary, the HT-29 cell line is a pivotal tool in medical and biological research, facilitating a deeper understanding of human colon adenocarcinoma, the molecular basis of cancer cell differentiation, and the development of effective cancer treatments.

Karyotype	The stemline chromosome number is hypertriploid with the 2S component occurring at 2.4%. Seventeen marker chromosomes are found in most metaphases, generally in single copy per chromosome. The marker designations are: M1p-(=t(3p-,?) with a deleted short arm), t(7q,?), t(10q,?), i(13q), 19q+a. M6, ?t(8q,9q-), ?xp, M9, 6q+, t(13,?)a, t(13,?)b, 19q+b, M14, M15, 15p+, and xq-. Chromosome 13 is nullisomic and chromosomes 8 and 14 are generally monosomic. No Y chromosome was detected by QM band analysis.

Culture Medium	EMEM, w: 2 mM L-Glutamine, w: 1.5 g/L NaHCO3, w: EBSS, w: 1 mM Sodium pyruvate, w: NEAA (Cytion article number 820100c)
Medium supplements	Supplement the medium with 10% FBS
Passaging solution	Accutase
Doubling time	24 hours
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.
Split ratio	A ratio of 1:3 to 1:8 is recommended
Seeding density	3 x 10^4 cells/cm^2
Fluid renewal	2 to 3 times per week
Freezing recovery	Slow, the cells need roughly 48 hours to settle and adhere.
Freeze medium	CM-1 (Cytion catalog number 800100) or CM-ACF (Cytion catalog number 806100)
Handling of cryopreserved cultures	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. Optionally, skip centrifugation but remove any remaining freezing medium after 24 hours. 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.
