Australian researchers’ perceptions and experiences with stem cell registration

The recently issued ISSCR standards in stem cell research recommend registration of human pluripotent stem cell lines (hPSCs). Registration is critical to establishing stem cell provenance and connecting cell lines to data derived on those lines. In this study, we sought to understand common barriers to registration by conducting interviews with forty-eight Australian stem cell stakeholders, including researchers, clinicians, and industry professionals. Australian stem cell researchers do not routinely register their lines, and only a third of those Australian lines captured by an international registry have fully completed the registration process. Most registered Australian cell lines lack complete information about their ethical provenance or key pluripotency characteristics. Incomplete registration is poorly aligned with the goals of open science on which registries are founded. Users also expressed concerns about the quality of the incomplete information provided to the resource. Registration was considered negatively, for instance as a hurdle or barrier to publication, which impacted on user perceptions of usefulness of registration and lowered the likelihood that they would engage with registries to find resources. Broader adoption of registration by journals, and continued advocacy by stem cell societies, will be important levers for awareness and engagement with registration. Although the Australian community represents a small fraction of potential registry users, the results of this study suggest ways for journals, registries, funders, and the international stem cell community to improve registration compliance.
