Fig. 2From: Mesenchymal stem cells promote human melanocytes proliferation and resistance to apoptosis through PTEN pathway in vitiligoPTEN pathway was activated in active vitiligo lesions. a–c Immunohistochemical staining for melanin, PTEN, p-S473-AKT, and AKT; magnification, × 100; scale bar, 200 μm. d–f Quantification of immunohistochemistry data with Image-Pro Plus 6.0. g Immunoblotting analyses of PTEN, p-S473-AKT, and AKT. Qualification of immunoblotting bands was calculated by using Image-Pro Plus 6.0. Data analysis was performed by using SPSS 20.0. ns represents no statistical significance, * represents P value < 0.05, ** represents P value < 0.01, *** represents P value < 0.001, and **** represents P value < 0.0001Back to article page
