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

Hair follicle-associated-pluripotent (HAP) stem cells are located in the bulge area of the hair follicle, express the stem-cell marker, nestin, and have been shown to differentiate to nerve cells, glial cells, keratinocytes, smooth muscle cells, cardiac muscle cells, and melanocytes. Transplanted HAP stem cells promote the recovery of peripheral nerve and spinal cord injuries and have the potential for heart regeneration as well. In the present study, we implanted mouse green fluorescent protein (GFP)-expressing HAP stem-cell spheres encapsulated in polyvinylidene fluoride (PVDF)-membrane cylinders into the severed sciatic nerve of immunocompetent and immunocompromised (nude) mice. Eight weeks after implantation, immunofluorescence staining showed that the HAP stem cells differentiated into neurons and glial cells. Fluorescence microscopy showed that the HAP stem cell hair spheres promoted rejoining of the sciatic nerve of both immunocompetent and immunodeficient mice. Hematoxylin and eosin (H&E) staining showed that the severed scatic nerves had regenerated. Quantitative walking analysis showed that the transplanted mice recovered the ability to walk normally. HAP stem cells are readily accessible from everyone, do not form tumors, and can be cryopreserved without loss of differentiation potential. These results suggest that HAP stem cells may have greater potential than iPS or ES cells for regenerative medicine.
