| Outline of Final Research Achievements |
When chondrocytes prepared from cartilage are expanded in monolayer culture, fibroblast-like cells gradually prevail. Although these prevailing fibroblast-like cells are believed to emerge because of the dedifferentiation of chondrocytes, the definite origin of the prevailing fibroblast-like cells has not been determined. We herein examined whether the prevailing non-chondrocytic cells observed after monolayer expansion culture arise from dedifferentiating chondrocytes or are the result of the overgrowth of fibroblasts that are present at the start of the culture. We also evaluated whether chondrocytes dedifferentiate because they proliferate or because they are cultured in monolayers.
