RESUMO

Objective To analyze interspecies cross-contamination of 160 non-human cell lines.Methods One hundred and sixty common non-human cell lines were collected and their species were identified by PCR.For the suspicious cells,chromosome analysis was further used to confirm their species.Results Six in 160 non-human cell lines were cross-contaminated.A rat cell line was mixed by a human cell line,and 5 were totally cross-con-taminated,and were indentified as wrong species.Conclusions Species identification is an indispensable part of cell quality control.Each cell line should undergo a full QA(Quality Assurance)assessment before it is used for research.
