| Research Abstract |
We analyzed phenotypes of DDR2 transgenic mice and ATDC5 cell lines with a focus on growth and size control. In previous study, cartilage cell proliferation decreased in DDR2 KO mice, and we analyzed also the function of DDR2 in cartilage tissue. We produced Ddr2 cDNA transgenic mice, which were specifically overexpressed only in the cartilage cells, but there were no prominent phenotypes in cartilage tissue of the transgenic mice.
To understand the role of Ddr2 in chondrocyte proliferation and differentiation, we next performed knockdown experiments using Ddr2 miRNA in ATDC5 cells. We found that DDR2 might repress cell proliferation and differentiation in cartilage cells.
DDR2 is suggested to have important function especially in the reproductive organs by the expression in various tissues.
