Effect of intrathecal injection of mesenchymal stem cell-neural progenitors on cerebrospinal fluid biomarkers in progressive multiple sclerosis.
Article in Stem cells translational medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Mesenchymal stem cell-neural progenitors (MSC-NP) are a bone marrow mesenchymal stem cell-derived population of cells with trophic and immunomodulatory properties with therapeutic potential in multiple sclerosis (MS). Early phase clinical trials have investigated the safety and efficacy of intrathecal administration of autologous MSC-NPs in people with progressive MS. To better understand the biological response to MSC-NP treatment, we analyzed cerebrospinal fluid (CSF) biomarkers in 2 separate cohorts of trial subjects with secondary progressive or primary progressive MS from both a phase 2 trial (n = 50) and an expanded access trial (n = 43) who received repeated administrations of autologous MSC-NPs. Candidate biomarkers identified through proteomic screening were validated in both cohorts, revealing a panel of 4 biomarkers (CCL2, C-C motif chemokine ligand-2; MMP9, matrix metalloproteinase-9; SCF, stem cell factor/c-kit ligand; and CHIT1, chitotriosidase-1) that were significantly changed in CSF but not serum following treatment. Other MS biomarkers neurofilament light and glial fibrillary acidic protein were unchanged following treatment but correlated with age, and both age and Expanded Disability Status Scale (EDSS), respectively. The specific biomarker changes observed following MSC-NP injections suggest distinct biological effects following MSC-NP treatment. These biomarkers help define the pharmacodynamic response to MSC-NP treatment as well as guide the design of future clinical studies.
