ABSTRACT
BACKGROUND:
A superior composite scaffold hopes be constructed to resolve adhesion between seed cell and scaffoldmaterial.OBJECTIVE:
To construct composite scaffolds with fibrin glue and xenogeneic inorganic bone and to explore the three-dimensional culture of rabbit marrow stromal cells (MSCs).DESIGN, TIME ANDSETTING:
Observational experiment was performed at the Department of Orthopedics of China-Japan Union Hospital and the Department of Mechanical Engineering, College of Mechanical Engineering of Jilin University from November 2007 to March 2008.MATERIALS Fibrin glue was made by a certain ratio of fibrinogen and thrombin; bovine cancellous bone following defatting and deproteinization was mixed with fibrin glue to establish composite scaffold.METHODS:
Rabbit MSCs were cultured in v#ro and transferred, and the MSCs were collected for three-dimensional culture withcombined scaffolds made of xenogeneic inorganic bone and fibrin glue.MAIN OUTCOMEMEASURES:
The growth and proliferation of MSCs were examined by phase-contrast microscope andtransmission electron microscopy.RESULTS:
Phase contrast microscope showed that the MSCs could spread evenly in the combined scaffolds. After cultured 4 weeks, the MSCs formed into densely three-dimensional net. It could be observed under the transmission electron microscopethat there were micro-protrusions in local stromal cells at 4 weeks after culture, and the mitochondrion as well as ribosomes wasobserved in the cytoplasm with rough endoplasmic reticulum.CONCLUSION:
The MSCs cultured in the combination of fibrin glue and xenogeneic inorganic bone scaffolds show a betteractivity, and they can proliferate rapidly.
