1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundStem cell exhaustion and cellular senescence are two hallmarks of aging. Mesenchymal stem cells (MSCs), as key players in tissue regeneration, are particularly vulnerable to senescence, which compromises both their endogenous regenerative capacity and their therapeutic efficacy in cell-based applications. Suppressing MSC senescence is therefore essential for developing effective regenerative and anti-aging strategies.

methodsWe developed a serum-free adipose-conditioned medium (SF-ACM) from in vitro-cultured human adipose explants. Its anti-aging effects were evaluated in oxidative stress-induced and replicative senescence models of human adipose-derived stem cells (ADSCs), assessing proliferation, senescence markers, migration, and trilineage differentiation. Parallel experiments in senescent human dermal fibroblasts (HDFs) examined proliferation, fibrosis, and senescence features. In vivo, male C57BL/6 J mice (4 or 16 months old) with D-galactose-induced and naturally aged mice received intraperitoneal SF-ACM. Aging phenotypes were analyzed in skin, adipose tissue, muscle, kidney, and serum, along with hepatic and renal safety assessments.

resultsSF-ACM significantly reduced senescence-associated markers, including p16, p21, p53, and SA-β-gal, enhanced Lamin B1 expression, and improved the proliferation, migration, and differentiation capacities of ADSCs. It also decreased senescence and fibrosis-related markers in HDFs. In aging mice, SF-ACM improved aging-associated phenotypes in skin, adipose tissue, and skeletal muscle. Mechanistically, these effects were associated with suppression of the IL-6/STAT3 signaling pathway.

conclusionsThis study identifies a novel xenogeneic-free, paracrine-rich formulation that delays cellular senescence and preserves tissue homeostasis. These findings support its potential as a safe and effective strategy to suppress cellular aging, restore stem cell function, and ameliorate tissue-level aging, offering translational promise for regenerative medicine and anti-aging interventions.
