Paeoniae alba Radix Promotes Peripheral Nerve Regeneration

Figure 1

Effects of PR extract on the morphology of PC12 cells. The cells were treated for 72 h without PR extract in the absence of NGF (a), without PR extract in the presence of NGF (b), with PR extract in the presence of NGF ((c) PR at 1.25 μg ml⁻¹; (d) PR at 12.5 μg ml⁻¹; (e) PR at 125 μg ml⁻¹). It was noted that the PR could stimulate the NGF-induced neurite outgrowths (arrows) from PC12 cells. Scale bars = 100 μm.
