Abstract:

BACKGROUND: The relationship between placing time after stem cell preparation and cell survival is the basis of safety and effectiveness for the clinical application.
OBJECTIVE: To observe effects of different preservation solutions and different storage time on survival rate of umbilical cord-derived mesenchymal stem cells, and to provide important evidence for identifying effectiveness of stem cells.
METHODS: Umbilical cord-derived mesenchymal stem cells were selected to prepare stem cell preparation, which was preserved in physiological saline, medium, medium+physiological saline, physiological saline containing epidermal growth factor, and medium containing low molecular heparin calcium suspension. Cold closet was selected for imitating cellular transport conditions. Samples were obtained at 0, 6, 12, 18, 24, 30, 36, 42 and 48 hours. Total cell number and cell survival rate were detected.
RESULTS AND CONCLUSION: The difference in cell number and survival rate was not great within 24 hours in each group. Twenty-four hours later, total cell number and survival rate were better in the medium and medium containing low molecular heparin calcium groups than in the physiological saline containing epidermal growth factor, physiological saline, and medium+physiological saline groups. These findings suggest that after stem cell preparation, the cell survival rate can reach more than 90% within 24 hours under refrigerated transport conditions. Nutritional ingredients and proper pH value of preservation solution can make the cell survival rate increased greatly.
