Scan verdicts. Open evidence only when needed.

Claim 1 of 5Not checkedCurrent GMP standards for cell therapies assess identity, viability, sterility, and genetic stability, while EV product guidance adds particle size, concentration, markers, morphology, contaminants, endotoxin, and assays, but these checks rarely evaluate protein homeostasis in donor cells.View evidenceHide evidence

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 2 of 5Not checkedBecause EV cargo reflects parent-cell state, these protein-handling defects may be transmitted to recipient cells, and the authors argue that deeper research is needed into proteostatic quality control across MSC- and iPSC-derived products.View evidenceHide evidence

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 3 of 5Not checkedDuring ex vivo expansion, stem cells can accumulate senescent cells that release inflammatory factors and damaged proteins; senescent cells show declining heat shock responses, proteasomal activity, and autophagic flux, reducing their capacity to handle misfolded proteins.View evidenceHide evidence

Claim 4 of 5Not checkedThe review proposes practical steps such as cell-source selection, senescence gating, EV proteomic profiling, and pre-transplantation cargo sanitization, and says donor-cell protein quality control should be treated as a release-critical attribute.View evidenceHide evidence

Claim 5 of 5Not checkedFor neurodegenerative applications, assays for misfolded or oxidized SOD1 could serve as exclusion criteria, but peptide-based sanitization still needs safety and scalability testing.View evidenceHide evidence
