General information
| Description | The LS147T cell line is a variant of LS-180, both of which are derived from a Duke's type B adenocarcinoma of the colon in a 58-year-old White female patient. The original LS-180 line was established by culturing the minced tumor tissue for 10 months. LS-147T, along with its parent line, is notable for its expression of multiple oncogenes including myc, myb, ras, and fos, while being negative for others like sis, abl, and ros. This line also expresses high levels of carcinoembryonic antigen (CEA), interleukin 6 (IL-6), and interleukin 10 (IL-10), which are important markers and potential targets in colorectal cancer research. These cells exhibit several key characteristics of colonic epithelial cells, including abundant microvilli and intracytoplasmic mucin vacuoles, which are features typically associated with secretory cells in the colonic mucosa. Electron microscopy studies have confirmed these structural details, further supporting their origin and differentiation status. Importantly, LS-147T cells have been shown to be tumorigenic in immunodeprived mice, consistently producing tumors when inoculated subcutaneously at high cell densities, thus affirming their malignant potential. Moreover, the LS-147T cell line is particularly valuable in studies focusing on the molecular and immunological aspects of colorectal cancer. It has been reported that this line is easier to subculture compared to its parent line, LS-180, making it a more practical choice for long-term studies. The robust production of CEA by these cells, which is significantly higher than that of other established lines like HT-29, makes LS-147T a critical model for understanding tumor marker dynamics and exploring targeted therapies in colorectal cancer. |

Handling
| 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. |
| Seeding density | 5 to 8 x 104 cells/cm2 |
| Fluid renewal | 2 to 3 times per week |
| Post-Thaw Recovery | After thawing, plate the cells at 5 x 104 cells/cm2 and allow the cells to recover from the freezing process and to adhere for at least 24 hours. |
| Freeze medium | As a cryopreservation medium, we 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 |
|
| Incubation Atmosphere | 37°C, 5% CO2, humidified atmosphere. |
| Shipping Conditions | 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. |
| Storage Conditions | 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. |
Quality Control & Molecular Analysis
| 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. |
