Abstract:

BACKGROUND: Mesenchymal stem cells have pluripotent differentiation, and can promote cell engraftment and immune regulation. Therefore, we attempt to use human umbilical cord mesenchymal stem cells as a new source for treatment of lung cancer by exploring cell isolation, identification and transplantation combined with chemotherapy for lung cancer in mice.
OBJECTIVE: To investigate the isolation and identification of human umbilical cord mesenchymal stem cells and its transplantation combined with chemotherapy for lung cancer in mice.
METHODS: Human umbilical cord mesenchymal stem cells were isolated from fresh umbilical cord of newborns and identified using tissue culture and enzyme digestion. Twenty Balb/C nude mouse models of lung cancer were randomly divided into two groups: mice in chemotherapy group were given chemotherapy, and those in combined group given combination of chemotherapy with human umbilical cord mesenchymal stem cell transplantation.
RESULTS AND CONCLUSION: Compared with the chemotherapy group, the gastrointestinal tract was rosy and shiny, intestinal mucosa was smooth and complete, and tumor mass and blood indexes significantly decreased in the combined group (P < 0.05). To conclude, mature human umbilical cord mesenchymal stem cells can be obtained by tissue culture and enzyme digestion, and the cell transplantation combined with chemotherapy can significantly reduce gastrointestinal tract damage and the make peripheral hemogram in a stable level.
