Fig. 7From: Extremely low frequency electromagnetic fields promote mesenchymal stem cell migration by increasing intracellular Ca2+ and activating the FAK/Rho GTPases signaling pathways in vitroFAK-mediated Rho GTPase activation induces F-actin organization after electromagnetic field (EMF) exposure. Immunofluorescence analysis of F-actin polymerization was performed using rhodamine phalloidin (F-actin; green). Nuclei were stained with DAPI (blue). An overlay of the two fluorescent signals is shownBack to article page
