1 · What the graph read from it

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.

2 · The registry

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

In Parkinson's disease, progressive loss of dopaminergic neurons in the substantia nigra pars compacta (SN) leads to debilitating motor dysfunction. One current therapy aims at exogenous cellular replacement of dopaminergic function by transplanting fetal midbrain cells into the striatum, the main projection area of the SN. However, results using this approach have shown variable success. It has been proposed that cellular replacement by endogenous stem/progenitor cells may be useful for therapeutic interventions in neurodegenerative diseases, including Parkinson's disease. Although it is widely accepted that progenitor cells are present in different areas of the adult CNS, it is unclear whether such cells reside in the adult SN and whether they have the potential to replace degenerating neurons. Here, we describe a population of actively dividing progenitor cells in the adult SN, which in situ give rise to new mature glial cells but not to neurons. However, after removal from the SN, these progenitor cells immediately have the potential to differentiate into neurons. Transplantation of freshly isolated SN progenitor cells into the adult hippocampus showed that these cells also have a neuronal potential under in vivo conditions. These results suggest that progenitor cells reside in the adult SN and can give rise to new neurons when exposed to appropriate environmental signals. This developmental potential of SN progenitor cells might be useful for future endogenous cell replacement strategies in Parkinson's disease.
