Abstract:

BACKGROUND: Adipose-derived mesenchymal stem cells are often used for tissue repair and functional reconstruction due to their paracrine actions of multiple growth factors, easy access and immunomodulatory effects. The prevention and treatment of esophageal stenosis after esophageal endoscopic submucosal dissection is a challenge for doctors and patients. Adipose-derived mesenchymal stem cell transplantation combined with the cell sheet technology has the potential to promoting wound repair and preventing esophageal stenosis. 
OBJECTIVE: To investigate the biological characteristics of adipose-derived mesenchymal stem cell sheet, and to analyze the feasibility of preventing esophageal stenosis after esophageal endoscopic submucosal dissection. 
METHODS: The green fluorescent protein-labeled adipose-derived mesenchymal stem cell sheets were prepared using temperature-sensitive culture dishes and were set as the experimental group. Conventionally adherent adipose-derived mesenchymal stem cells were used as the control group. Levels of vascular endothelial growth factor, transforming growth factor β1 and hepatocyte growth factor in the two groups were compared by ELISA, RT-qPCR and western blot. The skin ulcers of nude mice were prepared, and randomized into cell sheet group and model group. The green fluorescent protein-labeled adipose-derived mesenchymal stem cell sheets were then implanted into the skin wound in the cell sheet group. 
RESULTS AND CONCLUSION: The number of cells in the cell sheet was high with enriched extracellular matrix, and there was an interconnection between cells. The expression levels of vascular endothelial growth factor, transforming growth factor β1 and hepatocyte growth factor in the experimental group were all higher than those in the control group. The adipose-derived mesenchymal stem cell sheet on the back of nude mice was successfully transplanted, and the wound healing in the cell sheet group was faster than that of the model group. Experimental findings indicate that adipose-derived mesenchymal stem cell transplantation combined with the cell sheet technology is feasible to prevent stenosis after esophageal endoscopic submucosal dissection, but a large number of basic and clinical studies are warranted.
