Differential expression of microRNA (miRNAs) in milk-derived extracellular vesicles (MDEs) from mothers with ulcerative colitis (UC), Crohn’s disease (CD), and healthy controls. The expression profiles of miR-148, miR-320, Let-7a, and miR-21a were analyzed within each subgroup (UC and CD) by quantitative real-time polymerase chain reaction (qRT-PCR). qRT-PCR results were calculated using the 2^(−∆∆CT) method, and values were normalized against RNU6. *P < .05, **P < .01.
