| Outline of Final Research Achievements |
Calcification is an essential process for the formation of hard tissues. And ectopic calcification causes many diseases. However, the mechanism of calcification has been not cleared yet. It has been unknown whether the mechanisms of normal and ectopic calcification are identical. To identify molecules constituting the MV and elucidate the calcification mechanism, we studied using ATDC5 cells. The calcification of ATDC5 in the differentiated state is stimulated by the addition of inorganic phosphorus (Pi). Our results showed that the MVs were formed in the undifferentiated state. It was suggested that ATDC5 cells formed both MV without calcification ability and MV with calcification ability, depend on their differentiation state. Moreover, when ATDC5 cells differentiating to the articular cartilage-like cell, MV formation was observed but their calcification was not observed. We compared the MVs of these differentiated states and identified molecules necessary for the calcification.
