Stem cell sheet fabrication from human umbilical cord mesenchymal stem cell and Col-T scaffold

The visual appearance of skin areas above the graft over time. The top row shows the shaved skin of the control group mice. The second, third, and fourth rows show skin areas above the Col-T scaffold, stem cell sheet, and porcine tissue graft, respectively. The red arrow shows the area of skin turning pale and sign of caseation. The blue arrows indicate the scaffold and cell sheet graft. The green arrows show that the fur regenerated normally. The engraftment of the scaffold and cell sheet did not change the skin above the graft texture, or colour, and did not affect the fur regeneration rate.
