Cell line: | HELA |
DSMZ no.: | ACC 57 |
Species: | human (Homo sapiens) |
Cell type: | cervix carcinoma |
Origin: | established from the epitheloid cervix carcinoma of a 31-year-old woman in 1951; later diagnosis changed to adenocarcinoma; first aneuploid, continuously cultured human cell line |
Reference(s): | 14926, 14555, 18012, 18013 |
Biosafety level: | 1 |
Risk assessment: | The cell line is infected with papilloma virus type 18 (HPV-18). The cells contain several copies as proviruses integrated into the eukaryotic genome. The integrated virus genomes are incomplete and exhibit 2-3 kb deletions of the E2-L2 region. An activation and transmission of the HPV-18 during handling of the cell line is improbable. The cell line is categorized biosafety level 1. |
