Abstract
Cell lines are essential tools in biomedical research and drug discovery, often substituting for tissues or organs of origin. However, frequent misidentification and cross-contamination pose major quality control challenges, leading to unreliable data, hindering scientific progress, and impacting clinical translation. Even authenticated cell lines may undergo genetic and phenotypic changes over time, affecting experimental outcomes. To promote transparency, reproducibility, and rigor, the Journal of Cell Communication and Signaling (JCCS) reaffirms its commitment to best practices in cell line authentication and validation, in alignment with Wiley's publishing ethics. Authors submitting manuscripts must provide comprehensive cell line details, including species, sex, tissue origin, name, and Research Resource Identifier. They are also required to document the source, acquisition date, and authentication methods such as short tandem repeat (STR) profiling and adventitious agent testing, including mycoplasma screening. By enforcing strict guidelines, JCCS seeks to improve research integrity, reduce erroneous findings, and enhance reproducibility. This initiative not only strengthens the reliability of published studies but also supports the broader scientific community in accelerating discovery and translating research into clinical advances for better human health.
