Real-time visualization and modulation of endocytic dynamics in osteocytes in vivo.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Endocytosis is a critical cellular process involved in many physiological functions, including mechanotransduction. Recent advancements in intravital imaging have led to in vivo analysis of endocytosis, and these tools can now be translated to study the highly mechanosensitive bone tissue. Here, we present a live-cell study of endocytosis in osteocytes, mechanosensory cells embedded in mouse bone. Using intravital multiphoton microscopy and fluorescently labeled nanoparticles, we visualized real-time uptake and trafficking within osteocytes in vivo. We applied pharmacologic inhibitors to assess both general and receptor-specific modes of endocytosis. Our results demonstrate rapid and dynamic nanoparticle internalization by osteocytes, with distinct differences in uptake kinetics and subcellular distribution depending on nanoparticle surface functionalization. Notably, we observed sex-specific differences in dynamin-dependent endocytic activity. These results offer the first in vivo derived insights into how osteocytes take up materials and provide new evidence for chemically altering receptor-mediated endocytosis in live bone tissue.
