introduction: hela cell is a widely studied cell line derived from human cerzix adenocarcinoma. the cells are epithelial - like in morphology and susceptible to polio viruses and adenovirus type 5. hela cells are usually as monolayer for isolation and propagation of some human viruses, as well as for the expression of recombinant proteins, including hepatitis b surface antigen. the aim of this ...

We characterized the genomic variation of adenovirus type 5 isolates recovered from bone marrow transplant recipients in Seattle between 1976 and 1982. By restriction endonuclease analysis, we identified three new adenovirus genomic variants, each associated with a single invasive adenovirus infection. In addition, we were able to obtain suggestive evidence for a nosocomial spread of a particul...

We have investigated the responsiveness to growth factors (GFs) of primary baby rat kidney (BRK) cells transformed by the E1 region of adenovirus 5 or 12. The in vitro growth of non-oncogenic adenovirus 5-transformed BRK cells is largely independent of serum GFs, whereas growth of highly oncogenic adenovirus 12-transformed cells is strictly dependent on GFs present in serum. For the growth of a...
