ABSTRACT
BACKGROUND:
At present,most of the experiments on the treatment of skin wound by mesenchymal stem cells have been performed in rats,mice and rabbits,while the research on skin wound treatment by canine bone marrow mesenchymal stem calls is less reported.OBJECTIVE:
To observe the effect of canine bone marrow mesenchymal stem calls on skin wound healing.METHODS:
A 3 cmx3 cm wound was made on the both sides of the scapula and buttocks of the dog,with the right side as experimental group and the left side as control group.After the wound was made,allogeneic canine bone marrow mesenchymal stem calls suspension was injected subcutaneously around the wound in the experimental group on the 1st and 3rd days.The control group was injected subcutaneously around the wound with mesenchymal stem call culture medium on the 1st and 3rd days after the wound was made.Wound healing was observed dynamically in both groups.RESULTS ANDCONCLUSION:
In the 1st week,there were pale yellow inflammatory substances in the wound of two groups indicating obvious inflammations.Compared with the control group,the inflammatory substances were fewer and the growth rate of the granulation tissue was faster in the experimental group.From the 2nd week until the wound healing,epithelialization on the wound became obvious following the formation of the granulation tissue,which was mainly displayed by the formation of fresh epithelial tissues from the surrounding to the wound center.The epithelialization time of the experimental group was earlier than that of the control group,and the wound area of the experimental group was smaller than that of the control group.In the 3rd week,the wound in the experimental group healed completely,and became smoother than that in the control group.The wound area of the experimental group was slightly smaller than that of the control group on the 8th and 12th days after cell transplantation,and the healing speed of the experimental group was slightly faster than that of the control group,but there was no significant difference between the two groups.Our findings indicate that the transplantation of canine bone marrow mesenchymal stem cells has the possibility or trend to promote skin wound healing.
