Study on constructing tissue-engineered cartilage in different scaffolds in vitro
摘要
Abstract
Objective Try to construct the tissue -engineered cartilage and selection a better scaffold for the constructing. Methods Treating the first generation chondrocytes as the seeds which was separated from the SD rat. Through the adjusting the concentration of chondrocytes ,we can make the complex which is composed by cancellous bone matrix (BMG) / biological fibrin glue, chitosan/gelatin (Cs-gel) and chondrocytes. In different culture time, HE, toluidine blue (TB),Massons triad colour,immunohistochemistry, immunofluorescence and scanning electron microscope were used to test the complex. Results After co-culturing two weeks, we can certify the BMG/ biological fibrin glue is precendecer than Cs/gel.Concretly, the chondrocytes is uniform in BMG/biological fibrin glue,but not adqulis in Cs/gel. aggrecan and collagen Ⅱ is obviously in testing.But the longer the co-culturing, all tests display that special aggrean and collagen Ⅱ about chondrocytes are obvious at eight weeks the latter is better than the former. Conclusion Succeeding in constructing the tissue-engineered cartilage. In early culture,the growth,proliferation and secretion of chondrocytes in BMG/ biological fibrin glue was better.But Cs/gel have significallly advantage in longer co-culturing in vitro.关键词
