Abstract:
Objective To investigate the biomechanics of the tissue engineered tendons which use the embryonic tendon cells as the seed-cells and the silk as the scaffolds. Methods Two groups were set up with one as the group with tenocytes and the other as the group without tenocytes. Tissue engineered tendons were taken out at 2-week, 4-week, 6-week, 8-week post-operation, with 20 samples per-group each time. The values of biomechanics were measured and analyzed using the software SPSS 13.0. Results The biomechanical properties of the tissue engineered tendons in the group with tenocytes were significantly better than those in the group without tenocytes (P<0.05). In the group with tenocytes, the vitodynamics results got better with the increase of implantation time (P<0.05) except for the results of 8-week post--operation(P>0.05). But in the group without tenocytes, only the results of that from 8-week post-operation were of significant significance (P<0.05). Conclusion The results presented in the current study demonstrated that silk could stick tenocytes well, hold the characteristics of great resistance to draw after adhesion of tenocytes, and formed the tissue engineered tendon gradually in chickens, suggesting its potential application in the treatment of the defect of tendon.
