Enhanced effect of combining bone marrow mesenchymal stem cells (BMMSCs) and pulsed electromagnetic fields (PEMF) to promote recovery after spinal cord injury in mice. [PDF]

open access: yesMedComm (2020), 2022
The combination of bone marrow mesenchymal stem cells (BMMSCs) and pulsed electromagnetic fields (PEMF) improved the functional recovery in SCI mice by decreasing glial scar area, promoting the expression levels of nutritional factors, enhancing neuron preservation and axonal regeneration, which may be achieved by modulating Wnt/β‐catenin signaling ...
