Abstract:

BACKGROUND: Studies have shown that umbilical cord mesenchymal stem cells are ideal seed cells for tissue engineering research.
OBJECTIVE: To isolate, culture and identify tree shrew umbilical cord mesenchymal stem cells, in order to establish a standardized tree shrew umbilical cord mesenchymal stem cell lines.
METHODS: Caesarean-isolated tree shrew umbilical cord samples were used to isolate and culture umbilical cord mesenchymal stem cells using tissue explant adherent method. Flow cytometry assay was used to detect cell surface markers. Osteogenic and adipogenic induction media were used to induce umbilical cord mesenchymal stem cells to differentiate into osteoblasts and adipocytes.
RESULTS AND CONCLUSION: The cultured umbilical cord mesenchymal stem cells expressed CD90 and CD105 with the positive rate of 99.9% and 99.8% respectively. Hematopoietic stem cell marker CD34 expression rate was 0.0% and the endothelial cell marker CD31 expression rate was 0.7%, in line with the characteristics of umbilical cord mesenchymal stem cell surface markers. Calcium nodules by alizarin red staining and lipid droplets by oil red O staining were observed in the induced cells. These experimental findings indicated that umbilical cord mesenchymal stem cells from tree shrews capable of osteogenic and adipogenic differentiation were successfully isolated and cultured.
