RESUMEN
Objective To study the ultrastrueture of 3 types of periodontal cells, including periodontal ligament cells (PDLC), os-teoblast cells (OB) and eementoblast cells (CB). Methods After culturing 3 kinds of periodontal cells - PDLC, OB and CB, we observed them with transmission electron microscope. Results There was rich rough endoplasmic reticulum and lots of microfilaments in the cyto-plasm of CB and PDLC cells. There was rich rough endoplasmic in the cytoplasm of OB cells. Conclusion The main characteristic ultra-structure feature of the bovine CB and PDLC was rich rough endoplasmic reticulum and microfilaments in the cytoplasm. Compared with CB and PDLC, OB contained fewer microfilaments in the cytoplasm.
