Effect of hUCMSC-conditioned medium on neurite outgrowth from DRG explants.

(A) Morphology of DRG explants and staining for NF200 after 72-hour treatment with control medium, hUCMSC-conditioned medium or 50 ng/mL NGF. Scale bars: 500 μm. The neurite outgrowth distance (B) and percentage of axon area/DRG area (C) of the DRG explants were measured and calculated under a fluorescence microscope. All data are expressed as the mean ± SD. Statistical analysis was performed using one-way analysis of variance followed by Tukey's test. **P < 0.01, vs. blank medium. hUCMSCs: Human umbilical cord-derived mesenchymal stem cells; DRG: dorsal root ganglion; NF200: neurofilament 200; NGF: nerve growth factor.
