Live Imaging Microscopy of Human Retina Organoids: Photoreceptor Pathology.
Review in Advances in experimental medicine and biology, 2025. 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
Neurodegenerative diseases involve many different (sub)cellular pathologic processes like mitochondria damage, which are still incompletely understood and present future targets for therapy development. Live imaging microscopy of dynamic pathologic changes at single cell resolution might advance studies of pathomechanisms and biomarkers. Organoid technologies may complement and facilitate animal and patient studies: We recently reported a novel pathomechanism of photoreceptor degeneration via cell extrusion, identified and validated by live imaging in human retina organoids. Here, we describe the related workflow for live imaging organoid studies. As another use-case, we describe mitochondrial alterations in photoreceptors acutely damaged by the ionophore CCCP. Our data further support a CCCP-induced experimental model for photoreceptor pathology, which can be monitored by JC-1 live dye-assisted live imaging. Thus, we demonstrate that live imaging advances studies of early subcellular pathologic events in human organoids. Such approaches might facilitate future therapeutic target identification and development for early intervention.
