A Combinatorial Approach to Regenerate the Periodontal Ligament and Cementum in a Nondental Microenvironment

Figure 6

Immunohistochemical staining of TDMs transplanted into the greater omentum. BSP was positively expressed in the newly formed cementum-like structures in each cell-seeded group, especially in the lacunae (indicated by red arrows), while periostin was positively expressed in the newly formed periodontal ligament-like structure (indicated by green arrows), especially in the HERS + DFCs group. In the blank group (TDM only), there was no new tissue formation or attachment on the surface of TDM and the expression of BSP and periostin was negative.
