Abstract:

BACKGROUND: Fibrin is a kind of high polymer materials with biodegradation and good histocompatibility, and is a vector that can promote cell and exogenous growth factor release. Fibrin stabilizing factor XIII has been verified to contribute to the migration of undifferentiated mesenchymal stem cells in gel scaffold with high crosslinking, and promote cell proliferation and differentiation.
OBJECTIVE: To observe rat mesenchymal stem cell behavior in a fibrin gel.
METHODS: The rat fetal limbs cells was separated under the aseptic condition. The passage 3 cells were seeded in 0, 5, 10 and 20 g/L fibrin gel. Cell morphology was observed by inverted phase microscope and laser scanning confocal microscopy. Alkaline phosphatase activity and calcium deposition were measured respectively using a microplate reader and von Kossa staining.
RESULTS AND CONCLUSION: 5 g/L fibrin gel contributed to cell morphological changes, and 20 g/L fibrin gel contributed to osteogenic differentiation. Compared with the control group, alkaline phosphatase activity was higher in the formulations containing a 20 g/L fibrinogen concentration. Small mineralization nodules were observed at 21 and 28 days in a formulation containing both 10 and 20 g/L fibrinogen concentration, but no mineralization was detected in the control group. These results indicate that morphology and osteogenic differentiation of rat mesenchymal stem cells depended on the fibrinogen concentration, suggesting that fibrin gel is conducive to osteogenic differentiation of mesenchymal stem cells.
