Effects of Hypoxia and Chitosan on Equine Umbilical Cord-Derived Mesenchymal Stem Cells

Figure 9

Histology of cross sections at 7 (a–c) and 28 days (d–f). A hematoma is noted in treated defects (a, c, arrows) at 7 days, consistent with the implantation of cells in ACP. The empty defect (dashed arrow) is visible at day 7 (b). Defects are filled with tissue in all groups at 28 days (d, e, f). Masson’s trichrome, ×4 (bar = 1000 μm).
