TE-1 Cells
























General information
Description | The TE-1 cell line was derived from a well-differentiated squamous cell carcinoma of the esophagus. TE-1 cells are characterized by their epithelial morphology, growing as both isolated and piled-up colonies. Cytogenetic studies reveal a male karyotype and distinctive marker chromosomes. TE-1 cells are notable for their differentiation-associated structures, such as desmosomes and interdigitated microvilli, as observed under scanning electron microscopy. These cells also exhibit abundant organelles, including mitochondria and rough endoplasmic reticulum, as seen in transmission electron microscopy. When transplanted into immunodeficient mice, TE-1 cells form tumors that closely resemble the histological features of the original tumor, making them a reliable model for esophageal squamous cell carcinoma research. The cell line has been utilized to investigate molecular and cellular mechanisms of squamous cell carcinoma, including studies on epidermal growth factor (EGF) receptor expression and signaling. TE-1 cells demonstrate a reduced number of high-affinity EGF receptors compared to normal esophageal epithelial cells, and their response to EGF differs markedly. These features make TE-1 a valuable model for exploring the roles of growth factor signaling, tumor biology, and therapeutic resistance in esophageal squamous cell carcinoma. |

Handling
Culture Medium | RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a) |
---|---|
Medium supplements | Supplement the medium with 10% FBS |
Passaging solution | 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. |
Split ratio | 1:2 to 1:4 |
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. |

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. |
