PURPOSE: To investigate the source of the @entity4648 chondrocytes in the bilaminar zone following @entity890 ( @entity890 ) of @entity1348 ( @entity1348 ). METHODS: 12 Japanese adult @entity95 were randomly divided into A and B groups. Each group contained 4 experimental and 2 control @entity95 . The disc of the experimental @entity95 was induced forward and fixed into the holes made in the zygomatic arch. Group A was stained by HE and examined for the expression of @entity12914 ( @entity12914 ) and fibroblast growth factor receptor 3 (FGFR3) by immunohistochemical methods. Group B was observed under transmission electron microscopy (TEM). RESULTS: Chondrocytes appeared in the bilaminar zone of each experimental @entity95 . Both @entity12914 and FGFR3 were positive in part of them. Under TEM, some cells took on the double characters of chondrocyte and fibroblast and some others appeared the characters of naive cells. CONCLUSIONS: Following @entity890 of @entity1348 , some @entity4648 chondrocytes might be proliferated and differentiated from mesenchymal stem cells.
