Based on function and developmental fate, cartilage tissue can be broadly classified into two types: transient (embryonic or growth-plate) cartilage and permanent cartilage. Chondrocytes in transient cartilage undergo terminal differentiation into hypertrophic cells, induce cartilage-matrix mineralization, and eventually disappear and are replaced by bone. On the other hand, chondrocytes in permanent cartilage do not differentiate further, do not become hypertrophic, and persist throughout life at specific sites, including joints and tracheal rings. While many studies have described differences in structure, matrix composition and biological characteristics between permanent and transient cartilage, it is poorly understood how the fates of permanent and transient cartilage are determined. Previous studies demonstrated that chondrocytes isolated from permanent cartilage have the potential to express markers of the mature hypertrophic phenotype once grown in culture, suggesting that cell hypertrophy is an intrinsic property of all chondrocytes and must be actively silenced in permanent cartilage in vivo. These silencing mechanisms, however, are largely unknown. In this paper, we first review nature of chondrocytes in transient and permanent cartilages and then report the cloning and characterization of a novel variant of ets transcription factor chERG, hereafter called C-1-1, which might be involved in regulation of permanent cartilage development.
