Improving Bovine Embryo Development and Quality Using Bovine Oviductal Epithelial Cell-Derived Conditioned Medium (bOEC-CM).

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
backgroundThe embryo co-culture systems with the monolayer cultured cells are complex, unreproducible, and have a high probability of biological contamination. Therefore, nowadays, using conditioned media is a suitable alternative to these methods.
objectivesThis study aimed to investigate the impact of utilizing bovine oviductal epithelial cell-derived conditioned medium (bOEC-CM) on subsequent embryo development and quality.
methodsBovine embryos produced in vitro were cultured in a specific medium supplemented with either 5% charcoal-stripped FBS (Charcoled Strip Serum [CSS]) or 10% bOEC-CM from either Days 1 or 3 post-fertilization. Various parameters, such as cleavage rate, blastocyst formation, hatching rate and blastocyst quality, were assessed.
resultsThe results indicated that adding 10% CM from Day 1 significantly reduced the cleavage rate compared to using CSS on the same day (p < 0.05). Furthermore, the CSS and CM from both Days 1 and 3 increased blastocyst formation rates (p < 0.05). Notably, the addition of 10% CM on Day 3 significantly improved the hatching rate compared to the other groups (p < 0.05). Both CM and CSS were found to enhance the inner cell mass (ICM), trophectoderm (TE) and total cell numbers in blastocysts when used on both Days 1 and 3 (p < 0.05). Additionally, CM from Day 3 positively influenced the expression levels of development-specific genes in cultured embryos (p < 0.05).
conclusionOverall, the findings suggest that using bOEC-CM at a 10% concentration may provide a promising supplement even better than serum and traditional co-culture methods during the last 5 days of embryo culture.
