[Retracted] Human Umbilical Mesenchymal Stem Cells-Derived Microvesicles Attenuate Formation of Hypertrophic Scar through Multiple Mechanisms

Figure 3

Pathological examination of hypertrophic scar tissues in the rabbit ear model treated with PBS, HUMSCs-MVs, ointment, and DEX. Hypertrophic scar tissues were sectioned and examined by pathological staining. (a) H&E staining to reveal changes in fibrotic tissues in scar tissues treated with PBS, HUMSCs-MVs, ointment, and DEX. (b) Masson staining to reveal changes in collagen fibers in scar tissues treated with PBS, HUMSCs-MVs, ointment, and DEX. (c, d) The immunohistochemical staining to reveal α-SMA (c) and collagen I (d) expression. Magnification, 400x.
