| Outline of Final Research Achievements |
In the present study, we investigated the stem cell property of periodontal cells derived from Parry-Romberg syndrome patient (Romberg PDL cells). Romberg PDL cells expressed significantly higher levels of ICAM-1, NCAM-1 and SSEA-4 compared to normal PDL cells. In addition, adipogenic and osteogenic differentiation potentials of Romberg PDL cells were inferior to that of normal PDL cells. Pulsing neutral antibodies against ICAM-1, NCAM-1 and SSEA-4 improved their adipogenic and osteogenic differentiation potentials. Taken together, facilitating expression of ICAM-1, NCAM-1 and SSEA-4 appears to cause the phenotype of Parry-Romberg syndrome.
