| Effects： | No, nontumorigenic in athymic, nude mice for more than 12 months. Ref Stoner GD, et al. Establishment and characterization of SV40 T-antigen immortalized human esophageal epithelial cells. Cancer Res. 51: 365-371, 1991. PubMed: 1703038 |
| Comments： | The line has undergone more than 250 population doublings. Growth factor studies have shown that HET-1A is stimulated by calcium and inhibited by fetal bovine serum, transforming growth factor-beta 1, and transforming growth factor-beta 2. Fumonisin B1 produces growth inhibition and increased apoptosis in HET-1A cells. The synthetic retinoid CD437 (6-3-(1-adamantyl)-4-hydroxyphenyl-2-naphthalene carboxylic acid (AHPN/CD437)0 induces apoptosis of esophageal squamous HET-1A cells through the caspase-3-dependent pathway. |
| Complete Growth Medium： | The base medium for this cell line (BEBM) along with all the additives can be obtained from Lonza/Clonetics Corporation as a kit: BEGM, Kit Catalog No. CC-3170. ATCC does not use the GA-1000 (gentamycin-amphotericin B mix) provided with the BEGM kit. Note: Do not filter complete medium.
|
| Subculturing： | The flasks used should be precoated with a mixture of 0.01 mg/mL fibronectin, 0.03 mg/mL bovine collagen type I and 0.01 mg/mL bovine serum albumin dissolved in culture medium.
Subcultivation ratio: 1:3 to 1:4 Medium Renewal: Every 2 to 3 days.
