Cell interventions for longevity: define a clinical question before a product
“Anti-ageing” and “longevity” are broad marketing terms, not evidence that a cell product improves healthspan, function or survival.
Begin with a defined population and clinical problem. Chronological ageing is not a single indication, and a claim to “rejuvenate” the whole body cannot be evaluated without specifying who is treated, why, with what product and against which alternative. Research may instead study a defined syndrome such as frailty, a specific disease, a functional limitation or a measurable risk state.
Define the intervention at product level: cell source, autologous or allogeneic status, manipulation, dose, route, schedule, manufacturer, release tests and regulatory pathway. Results from one MSC product or disease cannot be transferred to another preparation or to general longevity. A trial record, biological mechanism, celebrity use or change in a laboratory marker is not product approval or proof of clinical benefit.
Choose outcomes that matter to participants. Function, mobility, falls, disability, cognition, quality of life, hospitalisation and survival are different from surrogate biomarkers. Epigenetic clocks, inflammatory markers or imaging can be exploratory outcomes, but a favourable biomarker change does not by itself show that a person is healthier, functions better or lives longer.
A credible study pre-specifies eligibility, comparator, randomisation and masking where feasible, clinically meaningful thresholds, follow-up, missing-data methods, adverse events and stopping rules. It also continues established prevention and treatment rather than asking participants to replace them with an unproven intervention. Safety follow-up must reflect the product, route and plausible delayed risks.
ISSCR states that substantially manipulated or non-homologously used cell interventions should be proven safe and effective for their intended use before marketing, and condemns premature direct-to-consumer commercialisation. Use the ISSCR clinical-translation guidelines and EMA/HMA warning to assess a proposal. A longevity programme should be labelled research unless the exact product and indication have the required authorisation and evidence.
