A total of 12 carcinoma cell lines of the human uterine cervix were established from 5 keratinizing and 5 nonkeratinizing squamous-cell carcinomas, and 2 small-cell carcinomas. Of these, 10 lines grew as adherent cells and 2 as floating aggregates. All lines showed (i) similarity in morphology to the primary tumor from which they were derived; (ii) high viability with relatively long doubling times (48-96 hr); (iii) absence of Mycoplasma and other bacteria, apart from one Mycoplasma-contaminated line; (iv) genetic heterogeneity by DNA-fingerprinting analysis; (v) absence of p53 mutation from exon 4 through 9; and (vi) the presence of HPV DNA sequence. Among the lines, 7 were infected by HPV-16, 3 by HPV-18, 1 by HPV-31, and 1 by HPV-33; the 2 cell lines derived from small-cell carcinomas contained HPV-18. Interestingly, 6 of the 7 cell lines containing HPV-16-type DNA harbored the same alteration of E7 at nucleotide position 647 (amino acid 29, AAT --> AGT, Asn --> Ser), whereas the 3 HPV-18-positive lines did not; 3 cell lines proved to have intact E1/E2 of HPV, suggesting the presence of episomally replicating HPV DNA as well as the integrated form, whereas the other 9 lines were shown to have integrated HPV. Taken together, these cell lines would be very useful for studying the biology of uterine cervical carcinoma.

The p1 genes of 60 Mycoplasma pneumoniae clinical isolates were sequenced and compared to previously reported p1 gene sequences. An AGT trinucleotide variable-number tandem repeat was identified that ranged in copy number from 5 to 14 among the isolates. In addition, a novel p1 gene variant named 2c was identified in 6 of the isolates.
