Methodological evaluation demonstrates trace-level qPCR detection of residual pluripotent stem cells in differentiated cell products, suggesting standardized limits enhance clinical therapy safety.
Residual PSC detection follows ultra‑trace‑analysis principles. LOD supports qualitative assessment. Assays employ PSC‑specific markers and proper references, with adaptation to differentiated cell populations from diverse PSC sources.
