Evaluating the long-term efficacy of umbilical cord-derived mesenchymal stem cell therapy in retinitis pigmentosa: findings from a 1-to-4-year follow-up.
Article in Stem cells translational medicine, 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
backgroundThe objective of this study was to assess the long-term effectiveness and safety of implanting mesenchymal stem cells derived from umbilical cord tissue (UC-MSC) in patients diagnosed with retinitis pigmentosa (RP).
methodsIn this single-center study with a retrospective design, 669 eyes received suprachoroidal implantation of 5 million UC-MSCs. Postoperative assessments were conducted on the first day, third month, and every 6 months thereafter. At each visit, evaluations included best-corrected visual acuity (BCVA), anterior segment and fundus examinations, fundus photography, optical coherence tomography, and visual field (VF) tests. Multifocal electroretinography (mfERG) and full-field stimulus threshold (FST) testing were performed at baseline and every 6 months post-therapy. Procedure-related ocular and systemic complications were methodically documented.
resultsA total of 669 eyes from 429 patients underwent surgical intervention. Bilateral procedures were performed in 240 patients, while 189 patients received surgery in only 1 eye. All 669 eyes completed the 12-month follow-up, while 265 eyes completed 2 years, 128 eyes completed 3 years, and 19 eyes completed 4 years of follow-up. No notable ocular or systemic complications were reported during the study duration. Statistically significant improvements in BCVA, VF, and mfERG central rings amplitude measurements were observed over time. FST testing revealed significant improvements in visual sensitivity in 27 patients.
conclusionsThis investigation confirms the long-term benefits and safety profile of suprachoroidal UC-MSC therapy in cases of RP, demonstrating significant improvements in BCVA, VF, mfERG, and FST test outcomes. The data support the feasibility and potential of cell-based therapies as a promising and effective strategy for managing degenerative retinal diseases.
