Implication

Experimental study demonstrates that porcine milk-derived exosomes stimulate intestinal epithelial proliferation in cellular and mouse models, highlighting their role in neonatal gut development.

Key Points

To determine the biological role of porcine milk-derived exosomes in neonatal intestinal tract development and epithelial cell proliferation.
Treated porcine intestinal epithelial cells (IPEC-J2) in vitro with milk-derived exosomes (27 ± 3 ng and 55 ± 5 ng total RNA) to assess proliferation via MTT, CCK-8, and EdU assays.
Quantified gene and protein expression of proliferative markers (CDX2, IGF-1R, PCNA) and apoptotic regulators (p53, FAS, SERPINE) alongside microRNAs using qRT-PCR and Western blotting.
Administered exosomes (0.125 μg and 0.25 μg total RNA) to mice in vivo and measured histological changes in intestinal villus height, crypt depth, and proliferation markers.
In vitro exosome treatment significantly increased IPEC-J2 cell proliferation, upregulated CDX2, IGF-1R, PCNA, and six microRNAs, while downregulating p53, FAS, and SERPINE expression.
In vivo exosome administration significantly increased mouse intestinal villus height, crypt depth, and the villus length-to-crypt depth ratio, accompanied by increased CDX2, PCNA, and IGF-1R and decreased p53 levels.
