Soft Tissue Repair with Easy-Accessible Autologous Newborn Placenta or Umbilical Cord Blood in Severe Malformations: A Primary Evaluation

Figure 4

Morphology and protein expression in amnion-SIS constructs. Amnion sutured to SIS was analyzed for protein expression at days 0 to 21. All amnion-residing cells expressed CD73, and epithelial cells expressed PCK at all time points (brown staining). A low expression of Ki67 and caspase 3 was detected up to day 14. On day 21, Ki67 was not detected and caspase 3 showed a slight increased expression. Single positive cells stain brown as indicated by the arrows. Magnification 40x (CD73 and PCK) and 60x (Ki67 and caspase 3).
