Abstract:

BACKGROUND: More assessments are required on the use of human umbilical cord mesenchymal stem cells in the treatment of skin ulcers.
OBJECTIVE: To explore the feasibility of human umbilical cord mesenchymal stem cells to promote skin ulcer healing in mice.
METHODS: Twenty C57 mice were randomized into control and treatment groups (n=10 per group). A longitudinal skin wound model was made on the back of the mouse with sterile scissors. The wound surface was about 2.5 cm×2.0 cm in size and the wound depth was about
5 mm. After modeling, 1 mL of human umbilical cord mesenchymal stem cells was injected into the wound in the treatment group, while the same volume of normal saline was given in the control group. The ulcer area of the two groups was measured every day, and the wound healing rate was calculated. The peri-ulcer tissue was taken at 0, 7, and 14 days after transplantation. The expression of vascular endothelial growth factor was detected by immunohistochemistry. The anti-nuclear antibody MAB1281 was detected by immunofluorescence staining to assess the residual rate of human umbilical cord mesenchymal stem cells around the ulcer.
RESULTS AND CONCLUSION: The skin ulcer in the treatment group healed more quickly than that in the control group (P < 0.05). The expression of vascular endothelial growth factor was higher in the treatment group than the control group (P < 0.05). There were more residual human umbilical cord mesenchymal stem cells at the day of transplantation, while the number of residual cells gradually reduced with the healing of skin ulcer. These findings indicate that human umbilical cord mesenchymal stem cells maybe promote the neovascularization by paracrine approaches, and thus facilitate the healing of skin ulcer in mice.
