Introduction

Nonunions pose complications in fracture management that can be treated using electrical stimulation (ES). Bone marrow mesenchymal stem cells (BMMSCs) are essential in fracture healing, although the effects of different clinical ES waveforms available in clinical practice on BMMSCs cellular activities is unknown.

Materials and Methods

We compared Direct Current (DC), Capacitive Coupling (CC), Pulsed Electromagnetic wave (PEMF) and Degenerate Wave (DW) by stimulating human-BMMSCs for 5 days for 3 hours a day. Cytotoxicity, cell proliferation, cell-kinetics and cell apoptosis were evaluated after ES. Migration and invasion were assessed using fluorescence microscopy and affected gene and protein expression were quantified.
