TE10 Cells
General information
| Description | The TE10 cell line is part of the TE-series, a collection of esophageal cancer models established in Japan, specifically from a well-differentiated squamous cell carcinoma of the esophagus. TE10 cells are notable for their epithelial morphology and growth in monolayer culture. These cells were derived from a primary lesion without prior radiation exposure, making them representative of untreated tumor biology. TE10 exhibits several key genetic alterations linked to esophageal cancer progression. These include amplification and overexpression of the c-erbB gene, co-amplification of the int-2 and hst-1 proto-oncogenes, and dysregulation of growth factors such as TGF-α and EGF-R. These molecular features make TE10 a valuable model for investigating pathways involved in tumor growth, such as the epidermal growth factor receptor (EGFR) signaling axis. In addition, the line has been used to study responses to targeted therapies and chemotherapeutic agents, shedding light on mechanisms of drug resistance. TE10 cells are also frequently used in invasion and migration assays due to their capacity to form colonies in soft agar and exhibit anchorage-independent growth. These characteristics highlight their utility in exploring the molecular drivers of metastasis. The cell line’s consistent performance in experiments focused on tumor biology and pharmacology makes it an important tool for translational cancer research, particularly for developing therapeutic strategies aimed at squamous cell carcinoma of the esophagus. |

| 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. |
