Abstract:

BACKGROUND: Bone marrow mesenchymal stem cells from chickens are important cell models for embryonic developmental biology, immunology and oncology research. However, it is difficult to keep bone marrow mesenchymal stem cells with good undifferentiated potential in a large-scale expansion system.

OBJECTIVE: To establish a culture system in vitro with laminin coating to expand bone marrow mesenchymal stem cells from chickens.
METHODS: Isolated bone marrow mesenchymal stem cells from chickens were seeded in laminin-coated plates and traditional two-dimensional plates, respectively. After expansion in vitro, the morphological characteristics, expression of surface markers, expansion characteristics and adipogenic differentiation of bone marrow mesenchymal stem cells in both conditions were analyzed and compared.
RESULTS AND CONCLUSION: There were no statistical differences in the morphological characteristics and expression of surface markers of bone marrow mesenchymal stem cells expanded by laminin-coated plates and traditional two-dimensional plates. But, the expansion characteristics and adipogenic differentiation of bone marrow mesenchymal stem cells cultured in laminin-coated plates were better than those in traditional two-dimensional plates. Laminin culture system could quickly amplify out of a large number of chicken bone marrow mesenchymal stem cells with better proliferation ability and undifferentiated performance. All above results indicated that a more efficient expansion system with laminin coating is established.
