The in vitro effect of MMP7 on Schwann cell migration. a Representative cell migration images of non-treated Schwann cells (Con) and Schwann cells treated with MMP7 recombinant protein (MMP7) at 12 and 24 h after cell culture. Scale bars represented 100 μm. Histograms showed summarized migration rates of non-treated Schwann cells and Schwann cells treated with MMP7 recombinant protein. The asterisk indicated significant different from non-treated control, * p-value < 0.05, n = 3. b Representative cell migration images of Schwann cells transfected with siRNA control, MMP7 siRNA1, and MMP7 siRNA2 at 12 h after cell culture. Scale bars represented 100 μm. Histograms showed summarized migration rates of Schwann cells transfected with siRNA control, MMP7 siRNA1, and MMP7 siRNA2. Asterisks indicated significant different from siRNA control, * p-value < 0.05, n = 3. c Representative cell migration images of Schwann cells transfected with siRNA control, MMP7 siRNA1, and MMP7 siRNA2 at 24 h after cell culture. Scale bars represented 100 μm. Histograms showed summarized migration rates of Schwann cells transfected with siRNA control, MMP7 siRNA1, and MMP7 siRNA2. Asterisks indicated significant different from siRNA control, * p-value < 0.05, n = 3
