Table 2. Summary of articles on the uptake and stability of bovine milk-derived EVs

Description References
Bovine milk-derived EVs are uptaken into the intestinal cell model (Caco-2) and have more beneficial features than liposomes. (Roerig et al., 2021)
EVs-encapsulated miRNA was stable in both in vitro and in vivo digestion, and it was confirmed that cellular uptake was possible and reached each organ upon oral administration to mice. (López de Las Hazas et al., 2022)
The drug-loaded bovine milk exosomes showed higher efficiency and targetability compared to the free drug in both cell and mouse tests. (Munagala et al., 2016)
Fluorophore-labeled bovine milk exosomes and miRNAs are uptaken by human colon carcinoma cells and rat small intestinal cells, which are mediated by endocytosis. (Wolf et al., 2015)
Milk exosomes crossed intestinal epithelial cells in in vitro culture, and milk exosomal miRNAs can resist in vitro digestion and cross the intestinal barrier. (Rani et al., 2017)
When fluorophore-labeled bovine milk exosomes and miRNA were orally administered, it was expressed in the organs of mice and pigs, confirming that interspecies transfer was possible. (Manca et al., 2018)
Postprandial blood analysis of newborn calves showed that bovine colostrum-derived EVs were transferred into the circulation but not miRNAs. (Kirchner et al., 2020)
Confirmation of uptake of bovine milk EVs into intestinal epithelial cells through fluorophore-conjugated lactadherin labeling. (Hansen et al., 2020)
Confirmation of bovine milk exosome uptake into differentiated THP-1 cells by flow cytometry and fluorescence microscopy. (Izumi et al., 2015)
Confirmation of uptake of PKH-labeled bovine colostrum-derived EVs into RAW 264.7 cells (Maburutse et al., 2017)
Resistance of miRNA and mRNA in milk with acidic conditions and RNase treatment. (Izumi et al., 2012)
Bovine milk exosomal long noncoding RNAs are protected from degradation during in vitro digestion system. (Zeng et al., 2019)
Bovine milk exosomal small interfering RNA resists in vitro digestive conditions and is uptaken into Caco-2 cells. (Shandilya et al., 2017)
bta-miR-223 and bta-miR-125b present in commercial cow milk are resistant in a computer-controlled gastrointestinal model (TIM-1). (Benmoussa et al., 2016)
The integrity and molecular structure of EVs in bovine milk are affected by Industrial processing. (Kleinjan et al., 2021)
Processing in commercial dairy plants have no statistical effect on the abundance value of miRNAs in dairy products. (Shome et al., 2021)
