Background and Mission

hPSCreg originated from projects funded by the European Commission and has grown into a globally recognized resource. Its core mission is to promote responsible research with human pluripotent stem cells by making reliable and standardized information about these cells openly available. The registry underpins transparency in the provenance, ethical sourcing, and scientific characterization of stem cell lines, thereby helping researchers select appropriate, well-documented cell lines for their experiments.

A key part of the registry's mission is to encourage compliance with ethical and legal standards governing the derivation and use of human pluripotent stem cells. By requiring documentation of donor consent, ethical approvals, and provenance information, hPSCreg helps ensure that cell lines listed in its database have been generated in accordance with recognized ethical frameworks.

What hPSCreg Does

hPSCreg functions as both a data repository and a service provider that supports the identification, registration, characterization, and dissemination of human pluripotent stem cell lines. Its activities cover several interconnected areas:

• Collecting and curating detailed information about individual hESC and hiPSC lines from providers worldwide.
• Assigning standardized, unique, and machine-readable names to each registered cell line to eliminate confusion caused by inconsistent naming conventions.
• Reviewing and validating ethical and provenance documentation associated with each cell line.
• Publishing verified data through an openly accessible web-based portal.
• Supporting the international harmonization of stem cell nomenclature and data standards.

Products and Services

Cell Line Registration and Unique Naming

One of hPSCreg's central services is the registration of human pluripotent stem cell lines and the assignment of a standardized unique name to each line. The registry uses an internationally agreed-upon naming standard that encodes information such as the depositor, the type of cell line, and other identifying attributes into a consistent, human- and machine-readable format. This standardized naming service is widely used by researchers, journals, and funding bodies to unambiguously identify cell lines in publications and datasets. Researchers can request a name for a new cell line directly through the registry.

Searchable Cell Line Database

hPSCreg provides a comprehensive, freely accessible, and searchable online database of registered pluripotent stem cell lines. Users can browse and query the database using a wide range of criteria, including cell line name, cell type (hESC or hiPSC), donor characteristics, disease association, genetic modifications, reprogramming methods, and the depositor or provider. Each cell line entry aggregates detailed information, allowing researchers to compare lines and select those most suitable for their scientific needs.

Detailed Cell Line Data Sheets

For each registered cell line, hPSCreg compiles structured data sheets that present information across multiple domains, including:

• Origin and derivation details, such as the source tissue and reprogramming or derivation methods.
• Donor information, including relevant clinical and phenotypic data where available.
• Genotype and genetic modification data, including disease-associated mutations and engineered alterations.
• Characterization data documenting pluripotency, differentiation potential, and quality control assessments.
• Ethical and legal information, including consent and ethics approval status.
• Availability and provider contact details.

Ethical and Provenance Evaluation

hPSCreg offers a service in which submitted cell lines undergo review of their ethical and provenance documentation. This includes assessment of donor informed consent, ethical committee approvals, and the legal basis for derivation and use. Cell lines that meet documented ethical standards are flagged accordingly, giving researchers confidence that the resources they use are ethically sourced. This service is particularly valuable for meeting the requirements of funding agencies, regulatory authorities, and scientific journals.

Support for Clinical-Grade and Research Cell Lines

The registry accommodates both research-grade and clinical-grade pluripotent stem cell lines. For lines intended for clinical or therapeutic applications, hPSCreg captures additional relevant documentation, supporting the growing field of regenerative medicine and cell therapy where traceability and quality assurance are critical.

Data Standards and Interoperability

hPSCreg contributes to the development and adoption of standardized data formats and ontologies for describing pluripotent stem cell lines. The registry supports interoperability with other biomedical databases and resources, enabling integration of cell line information into broader research infrastructures. This standardization work helps ensure that data remains consistent, comparable, and reusable across different platforms and institutions.

Integration with the Research Community

The registry serves as a bridge between cell line depositors, biobanks, and end users. It links registered cell lines to their originating publications and, where applicable, to biobanks and repositories from which the lines can be obtained. This connectivity streamlines the process of locating and acquiring specific stem cell lines for research purposes.

Who Uses hPSCreg

hPSCreg serves a broad international audience, including:

• Academic and clinical researchers seeking well-characterized stem cell lines.
• Biobanks and cell repositories depositing and sharing their collections.
• Scientific journals requiring standardized cell line identification in publications.
• Funding agencies and regulatory bodies requiring documentation of ethical compliance.
• Companies and institutions developing stem cell–based therapies and research tools.

Significance in the Field

By centralizing verified information about human pluripotent stem cell lines, hPSCreg plays an important role in advancing rigor, reproducibility, and ethical integrity in stem cell science. The registry reduces duplication of effort, helps prevent the use of misidentified or poorly documented cell lines, and promotes transparency in a rapidly expanding and scientifically significant research field. As a resource maintained by Charité – Universitätsmedizin Berlin, hPSCreg combines institutional credibility with a commitment to open access, making it a trusted and widely referenced tool for the global stem cell research community.

Summary

The Human Pluripotent Stem Cell Registry (hPSCreg), operated by Charité – Universitätsmedizin Berlin in Germany, is a public and freely accessible registry that collects, validates, and disseminates standardized information about human embryonic and induced pluripotent stem cell lines. Through its cell line registration and unique naming service, searchable database, detailed data sheets, ethical and provenance evaluation, and support for data standardization, hPSCreg provides essential infrastructure for transparent, ethical, and reproducible stem cell research worldwide.
