Controversy still exists regarding the origin of the cell source for cellular cementum (epithelial or mesenchymal). This disagreement may be partially due to a lack of understanding of the events leading to the initiation and development of the tooth roots and supportive tissues, such as the cementum. Osterix (OSX) is a transcriptional factor essential for osteogenesis, but its role in cementogenesis has not been addressed. In the present study, we first documented a close relationship between the temporal- and spatial-expression pattern of Osx and the formation of cellular cementum. We then generated 3.6-kilobase (kb) collagen type I (3.6-kb Col 1)-Osx transgenic mice, which displayed accelerated cementum formation versus wild-type (WT) controls. Importantly, the conditional deletion of Osx in the mesenchymal cells with two different Cre systems (the 2.3-kb Col 1 and an inducible CAG\u2013Cre estrogen receptor [CreER]) led to a sharp reduction in cellular cementum formation (including the cementum mass and mineral deposition rate) and gene expression of dentin matrix protein 1 (DMP1) by cementocytes. However, the deletion of the Osx gene after cellular cementum formed did not alter the properties of the mature cementum as evaluated by backscattered scanning electron microscopy (SEM) and resin-casted SEM. Transient transfection of Osx in the cementoblasts in vitro significantly inhibited cell proliferation and increased cell differentiation and mineralization. Taken together, these data support: (1) the mesenchymal origin of cellular cementum (from periodontal ligament [PDL] progenitor cells); (2) the vital role of OSX in controlling the formation of cellular cementum; and (3) the limited remodeling of cellular cementum in adult mice. \u00a9 2012 American Society for Bone and Mineral
