The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
Some of the secretions of senescent cells dampen stem cell activity and others promote stem cell activity.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

So we also know that the secretions of senescent cells can have very profound on stem cell proliferation and function. So it could also be that by dampening the secretory phenotype of senescent cells, you now release those stem cells from the suppression that was due to those secretory phenotypes and therefore allow them now to do what they do best, which is to proliferate and regenerate a tissue.
