cartilage cell
3.DATA SOURCES: The Medline was undertaken to identify the literatures of disci intervertebrals tissue engineering, seed cell, cartilage damage repair published from January 1999 to June 2006 with the Keywords of "disci intervertebrales,tissue engineering,seed cell,cartiage defect,cartiage repain" in English.
5.(4)T-cell subsets including CD4, CD8 and TGF-β1, bFGF in synovial and cartilage tissue of CIA rats were detected by Immunohistochemistry techniques;
6.The mean age was 13.5 years old. The histological grades were defined under the light microscope. The proliferation index(proliferation cell nuclear antigen,PCNA-index),apoptosis index(Poly ADP-ribose polymerase,PARP-index),PCNA/PARP ratio of chondrocytes and histological grades of cartilage in the inferior facet processes by immunohistochemistry were compared between the convex side and the concave side in AIS.
