Proteomic profile of Laser-dissected Motoneurons, Ependymal Cell Layer and Dorsal Root Ganglia after Spinal Cord Injury in the Rat.
Article in Scientific data, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Spinal cord injury induces profound molecular changes in surrounding tissue. Deciphering these changes with cell type-specific resolution shall facilitate discovery of new molecular targets that promote recovery. Here, we performed a proteomic analysis of laser-dissected motoneurons (MNs), ependymal cells (ECs), and dorsal root ganglia (DRG) obtained from adult rats 2 or 6 weeks after thoracic spinal cord transection at T11-T12 level, and control animals (n = 5-6 rats per group). We traced with fluorescent cholera toxin and laser-microdissected MNs innervating soleus muscle (SOL, n = 172 ± 39 MNs sections per animal, mean ± SD) and tibialis anterior muscle (TA, n = 262 ± 74 per animal) at lumbar spinal cord segments L3-L5. The ECs and DRG were dissected from the same lumbar segments. Mass spectrometry analysis of the samples allowed us to detect 1221 proteins in SOL MNs, 1186 in TA MNs, 1520 in ECs layer, and 5087, 3740 and 3086 in DRG L3, L4 and L5, respectively. Here we describe how this data was obtained and made available for further use. Our data may help to characterize molecular mechanisms regulated in the rat spinal MNs, DRG and ECs in the early and late period after spinal cord transection.
