A Study of Skeletal Stem Cell Dynamics and Its Potential Applications in the Design of a Titanium Implant for Senile Osteoporosis.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Traditional biomaterial design often prioritizes empirical knowledge over disease mechanisms and pathological dynamics, resulting in imprecise solutions in complex clinical conditions. Age-related osteoporosis (A-OP) is a disease associated with aging, characterized by a dysfunctional pathological microenvironment that hinders the osseointegration of conventional titanium implants. To develop a targeted titanium implant for A-OP, rat single-cell transcriptomics is integrated with human serum-derived transcriptome data to investigate dynamic changes in skeletal stem cells (SSCs) during aging, which guided the implant design. These findings reveal that hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs) within SSCs interact via a feedback loop: HSCs undergo premature senescence, leading to depletion of HSCs and secondary senescence of MSCs. Senescent MSCs exhibit adipogenic bias, perpetuating the pathological cycle of A-OP. Using core genes identified in the transcriptome analyses, resveratrol is selected and utilized it and a GelMA-chitosan hydrogel to decorate titanium implants for localized delivery. In the A-OP microenvironment, the hydrogel enables sustained responsive release of resveratrol, which reverses MSC senescence and redirects differentiation from adipogenic to osteogenic lineages, thereby breaking the pathological cycle. This multi-omics-driven implant design enhances precision and offers a novel methodology for biomaterial development.
