Electromagnetic fields counteract IL-1β activity during chondrogenesis of bovine mesenchymal stem cells.
This in vitro study examined whether electromagnetic fields (EMFs) influence chondrogenic differentiation of bovine mesenchymal stem cell pellets, with and without the inflammatory cytokine IL-1β. The authors report EMFs had limited effects on chondrogenesis in the absence of inflammation, but in the presence of IL-1β (and TGFβ3) EMF exposure was associated with recovery of proteoglycan measures and increased aggrecan and type II collagen expression. The findings are presented as EMFs counteracting IL-1β-mediated inhibition of chondrogenesis in this model.
Key points
- The study used bovine synovial-fluid MSC pellets differentiated for 3 and 5 weeks with TGFβ3.
- Conditions included absence/presence of IL-1β and EMF-exposed versus unexposed pellets.
- EMFs alone or with TGFβ3 were reported to have limited ability to promote chondrogenic differentiation.
- With IL-1β present, EMF exposure was associated with recovery of proteoglycan synthesis and content versus unexposed pellets.
- EMF-exposed pellets showed higher aggrecan and type II collagen mRNA expression under IL-1β conditions.
- Histology/immunohistochemistry indicated increased alcian blue, type II collagen, and aggrecan staining with EMF exposure in IL-1β conditions.
