RETRACTED: The Proliferation Enhancing Effects of Salidroside on Schwann Cells In Vitro

Figure 4

(a) Hematoxylin-eosin staining images showing the morphology of SCs cultured in vitro with different doses of salidroside (control: 0 mM, S-1: 0.1 mM, S-2: 0.2 mM, S-3: 0.4 mM) or NGF for 2, 4, and 6 days. Spindle-shaped bi- or tripolar SCs could be clearly observed (original magnification ×100). (b) Quantitative data of the mean number of SCs. Data of each bar are shown as the mean of three independent experiments ± SD. , , and compared with the control; , , and compared with the positive control (NGF).
