Morphological characteristics and distribution identification of telocytes in Tibetan sheep testis and epididymis.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Telocytes (TCs) are a type of stromal cell discovered in the various organs of different animals and have many potential functions, including angiogenesis, signalling, and substance transport. However, the TCs have not been detected in the testis or epididymis of Tibetan sheep. This study investigated the position, characteristics, and distribution of TCs in the testis and epididymis of Tibetan sheep using transmission electron microscopy (TEM), toluidine blue staining, immunohistochemistry, and double immunofluorescence to elucidate their possible functions. TEM revealed that TCs were often found near basement membranes and capillaries and were characterised by large nuclei, elongated cytoplasmic protrusions, and many secretory vesicles. We also observed via toluidine staining that TCs were present near basement membrane and interstitial capillaries. Immunohistochemistry and double immunofluorescence revealed the positive expression of CD117, vimentin, platelet derived growth factor receptor α(PDGFRα), PDGFRα + CD117, and PDGFRα + vimentin in TCs. Additionally, we inferred that TCs participates in the formation of the blood-testis and blood-epididymis barriers, as well as in material transport and a stable microenvironment. This study presents the first evidence of the presence of TCs near the basement membrane and blood vessels in the testis and epididymis of Tibetan sheep. These findings provide new insights into the function of TCs in the reproductive systems of plateau animals.
