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

Mature mammals are uniquely vulnerable to permanent auditory and vestibular deficits, because the cell proliferation that produces replacement hair cells in other vertebrates is limited in mammals. To investigate the cellular mechanisms responsible for that difference, we created excision lesions in the sensory epithelium of embryonic and 2-week-old mouse utricles. Lesions in embryonic utricles closed in <24 h via localized expansion of supporting cells, which then reentered the cell cycle. Pharmacological treatments combined with time-lapse microscopy demonstrated that the healing depended on Rho-mediated contraction of an actin ring at the leading edge of the lesion. In contrast, lesions in utricles from 2-week-old and older mice remained open even after 48 h. Supporting cells in those utricles remained compact and columnar and had significantly stouter cortical actin belts than those in embryonic sensory epithelia. This suggests that cytoskeletal changes may underlie the age-related loss of proliferation in mammalian ears by limiting the capacity for mature supporting cells to change shape. In mature utricles, exogenous stimulation with lysophosphatidic acid overcame this maturational block and induced closure of lesions, promoting supporting cell expansion and subsequent proliferation. After lysophosphatidic acid treatment, 85% of the mature supporting cells that had spread to a planar area >300 microm2 entered S-phase, whereas only 10% of those cells that had a planar area <100 microm2 entered S-phase. Together, these results indicate that cellular shape change can overcome the normal postnatal cessation of supporting cell proliferation that appears to limit regeneration in mammalian vestibular epithelia.
