Benchmarking study demonstrates high stability and differentiation fidelity in human induced pluripotent stem cells, suggesting a standardized reference for collaborative research.
Key Points
Identify and validate an optimal, standardized human induced pluripotent stem cell reference line to resolve phenotypic variability and enhance data comparability across research laboratories.
Sub-cloned candidate human iPSC lines and systematically profiled them using whole-genome sequencing, genomic integrity assays following CRISPR-Cas9 gene editing, and differentiation tests.
Distributed candidate line KOLF2.1J internationally for multicenter, head-to-head benchmarking against established laboratory-specific lines across diverse differentiation protocols and functional assays.
KOLF2.1J demonstrated consistent performance, robust differentiation across common target cell lineages, and genetic stability during CRISPR-Cas9 manipulation.
Head-to-head international testing confirmed superior multi-protocol performance, prompting the open distribution of KOLF2.1J and its gene-edited derivatives as a standard reference.
