  • STUDY OF ANTITHROMBOTIC FUNCTION OF ENDOTHELIUM IN VASCULAR TISSUE ENGINEERING

    Objective To investigate the current situation and developing trend of antithrombotic function study of endothelium in vasculartissue engineering. Methods The effect of several elements onthe antithrombotic ability of endothelium, including the source of endothelium,the characteristic of the matrix materials, the cell culture methods, and the endothelium’s gene modification were analyzed. Results The normal antithrombotic function of tissue engineered vascular relied on the source ofendothelium, gene modification of seeding cells, the cell culture methods in vitro, and the characteristic of the scaffolds. Conclusion The establishment of an ideal antithrombotic functional tissue engineering vascular still requires further studies in various aspects including seeding cells, matrix materials, and cell culture methods. Gene modification of vascular endothelium, which improves the antithrombotic ability, deserves more attention.

  • BIOCOMPATIBILITY STUDIES ON BIOACTIVE GLASS CERAMICS AND POLYLACTIC ACID COMBINED WITH CULTURED BONE MARROW STROMAL CELLS IN VITRO

    OBJECTIVE To study the biocompatibility on bioactive glass ceramics (BGC) and polylactic acid (PLA) combined with cultured bone marrow stromal cells (BMSCs) in bone tissue engineering. METHODS BMSCs were cultured combined with BGC and PLA in vitro, and the morphological characters, cell proliferation, protein content, and alkaline phosphatase activity were detected. RESULTS: BMSCs could be attached to and extended on both BGC and PLA, and normally grown, proliferated, had active function. BGC could promote cell proliferation. CONCLUSION The results show that both BGC and PLA have good biocompatibility with BMSCs, they can be used as biomaterials for cell transplantation in tissue engineering.

  • FUNCTIONAL ASSESS FOR RECONSTRUCTION OF TENDON IN FINGER AMPUTATION

    OBJECTIVE: To evaluate the function of injured hand after repair of finger stump and reconstruction of digit tendon attachment in finger amputation. METHODS: From 1992 to 1998, 20 cases with amputation of the 2nd to the 5th fingers were investigated, of which reconstruction of digit tendon attachment in 10 cases (group A) and routine operation without reconstruction of digit tendon attachment in other 10 cases (group B). After 6 months of operation, the tension test, fatigue test the sense of stability in motion and the perimeter of forearm in injured hand and the corresponding healthy hand were compared. RESULTS: The differences were remarkable (P lt; 0.01) between group A and group B in the tension test of injured finger, the fatigue test, the sense of stability in motion and the perimeter of injured arm. CONCLUSION: The digit of injured finger should be reconstructed in finger amputation in order to furthest maintain the function of injured hand.
