Electrical stimulation enhances neurogenin2 expression through β-catenin signaling pathway of mouse bone marrow stromal cells and intensifies the effect of cell transplantation on brain injury

► Electrically stimulated mBMSCs differentiate into neural cells. ► Electrically stimulated cells may contribute to the recovery of TBI model mice. ► mBMSCs are enhanced to express Ngn2 through β-catenin by electrical stimulation.
