STR DNA typing of human cell lines: detection of intra- and interspecies cross-contamination.
Inter- and intraspecies cross-contaminations (CCs) of human and animal cells represent a chronic problem in cell cultures leading to false data. Microsatellite loci in the human genome harboring short tandem repeat (STR) DNA markers allow individualization of cell lines at the DNA level. Thus, fluorescence polymerase chain reaction amplification of STR loci D5S818, D13S317, D7S820, D16S539, vWA...
متن کاملCross-contamination of human esophageal squamous carcinoma cell lines detected by DNA fingerprint analysis.
DNA "fingerprint" analysis has recently become known as a valuable technique for positive identification of any given individual. The chances for mistaken identity have been estimated to be 10(-6) for close siblings or as little as 10(-23) for randomly selected individuals. This methodology thus represents a significant improvement over previously established identification tests using protein ...
متن کاملIdentification of RD and L20B Cell Lines Cross-Contamination by Multiplex SYBR-Green PCR in Poliovirus Laboratory
Background and Aims: World Health Organization Global Polio Laboratory Network (GPLN) plays a critical role in the Global Polio Eradication Initiative. Cell culture methods (mostly RD and L20B cell lines) have been used for Enteroviruses and polioviruses isolation, respectively. Cross-contamination among L20B and RD cell lines causes the problem in accuracy of poliovirus surveillance and decrea...
متن کاملInduction of apoptosis in human tumor cell lines by platelets
Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thromb...
متن کاملInvestigation of Cross-Contamination and Misidentification of 278 Widely Used Tumor Cell Lines
In recent years, biological research involving human cell lines has been rapidly developing in China. However, some of the cell lines are not authenticated before use. Therefore, misidentified and/or cross-contaminated cell lines are unfortunately commonplace. In this study, we present a comprehensive investigation of cross-contamination and misidentification for a panel of 278 cell lines from ...
