Dose- and sex-dependent effects on umbilical cord-derived mesenchymal stem cell efficacy in regeneration of a full-thickness tendon defect in a rat model.
Article in Clinics in shoulder and elbow, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundMesenchymal stem cells (MSCs) have shown potential in regenerative medicine. In the present study the effects of MSC dosage and recipient sex on tendon regeneration were evaluated.
methodsA full-thickness tendon defect (FTTD) was created on supraspinatus tendons (SSTs) of rats and cryoprotective solution (CPS) and MSCs (0.05, 0.1 and 0.5 million MSCs [M-MSC] for female groups and 1.0 M-MSC for both female and male groups) were applied. After 2 and 4 weeks, macroscopic and histological evaluations were performed.
resultsTotal macroscopic scores were improved in all MSC groups compared with the CPS group, with no significant differences among the MSC groups. Furthermore, all MSC groups had lower total degenerative scores than the CPS group; however, only 0.1 M-MSC, 0.5 M-MSC, and 1 M-MSC groups showed significantly improved hyalinization compared with the CPS group at 4 weeks. Collagen organization and coherence were higher in all MSC groups than in the CPS group at both 2 and 4 weeks; however, 0.5 M-MSC and 1 M-MSC groups scored better than the 0.05 M-MSC group at 4 weeks. Heterotopic matrix analysis revealed smaller glycosaminoglycan (GAG)-rich areas in the 0.1 M-MSC, 0.5 M-MSC, and 1 M-MSC groups compared with the CPS group at 4 weeks. Overall, macroscopic and histological evaluations were not significantly different between female and male groups except for GAG-rich area.
conclusionsThe MSC dosage affected collagen and heterotopic matrix formation in a FTTD rat model; however, the efficacy of MSCs (1.0 M dose) in collagen regeneration was not affected based on the sex of the recipient. Level of evidence: I.
