The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
+ Standout tissues: • Skin: SRC −5.6 years vs WTC −4.4 years • Lung: SRC −4.1 years vs WTC −3.3 years • Skeletal muscle: SRC −4.9 / −3.5 years vs WTC −3.2 / −2.4 years • Spleen: SRC −2.6 years vs WTC −1.9 years • Hippocampus: SRC −2.0 years vs WTC −1.5 years
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.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
+ Age-related gene programs reversed: SRC 39% (upregulated) / 30% (downregulated); WTC reversed fewer (Fig. 2C–D, no exact percentages reported).
+ Average transcriptomic rejuvenation: SRC −3.34 years (54% of tissues) vs WTC −2.80 years (31% of tissues).
+ DNAmAge: Brain −5 years, skeletal muscle −4 years, spleen −2 years with SRC; WTC changes negligible.
Transcriptomic and epigenetic analyses confirmed biological age reversal in organs like skin, aorta, lungs, and the digestive system.
On average, this corresponded to estimated 3–5 years of biological age reversal, across 54% of tissues (vs 31% with WTCs).
+ Reproductive system: Ovaries SRC −4.5 years vs WTC −3.1 years; granulosa cells showed >6 years reversal with SRC.
+ Equivalent immune rejuvenation: SRC 3 years vs WTC 1.5 years (observational estimate, not author statistic).
SRCs outperformed conventional stem cells, reversing multiple hallmarks of aging across organ systems.
