| Research Abstract |
Based on our finding that Sp6 functions in not only morphological differentiation but also iron metabolism during tooth development, I performed a study to clarify a role of iron metabolism in the developmental control of Sp6. The iron supply for the ameloblast was the same as normal control in Sp6 Tg rat, suggesting two possibilities of the release imperfection from lysosomal ferritin and iron complex in the cell, or the secretion imperfection from the ameloblasts. Then, to further analyze the relationship between Sp6 and lysosomal function or secreting mechanism, I tried to condtruct the tet induction system for Sp6 using the dental epithelial cells that were originally established in my laboratory. Unfortunately, I could not lead to establish the tet inducible system by this moment. In addition, I found the involvement of Sp6 in Rock1 gene regulation, which is related to secretion mechanism.
