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

<div>Representative specimen harvested from greater omentum transplantation and histological staining. The specimen observation showed that the vascular net and soft tissue around the TDM were the most abundant in the HERS + DFCs group. The H&amp;E and Masson staining showed that, except for the blank group (TDM only), a layer of cementum-like structure (indicated by green asterisk) was formed around each TDM, in the surface of which there were periodontal ligament-like fibrous (indicated by red arrows) attachments. The width of the formed cementum-like structure in the HERS + DFCs group was larger than that of the HERS and the DFCs groups. Meanwhile, the periodontal ligament-like fibers were the longest and orderly arranged in the HERS + DFCs group than that of the HERS and the DFCs groups (<span class="nowrap"><svg height="13.532pt"
