초록

줄기세포는 미분화 상태의 세포로 지속적인 자가 분열능과 특정 세포로 분화 할 수 있는 분화능을 지니고 있으며 이러한 특성으로 말미암아 난치병의 새로운 장을 열 것이라는 기대감을 얻고 있다. 즉, 세포이식 후 특정 세포로 분화 유도를 시켜 기존의 치료 방법으로는 치료가 되지 않았던 많은 의학적 난제들을 풀 수 있는 열쇠인 것이다. 치아는 평생에 걸쳐 발거되는 조직으로 치아줄기세포는 얻기가 비교적 쉬워서 다른 성체줄기세포들보다 더 높이 평가되고 있다. 과잉치는 전 세계 다양한 인종에서 발견되는 중요한 임상적 질환이다. 과잉치의 유병율은 관련 연구 보고서마다 다양하나 소아치과 의사들의 경우 임상에서 자주 과잉치를 발거하고 있다. 그러나, 현재까지 진행된 줄기세포 관련 연구들을 살펴보면 과잉치의 줄기세포에 관한 보고는 없으며, 이는 줄기세포로 이용 가능한 중요한 자원을 파기하고 있는 것은 아닌지 의문이 생긴다. 그러므로 본 연구는 과잉치에 포함된 세포가 줄기세포의 특징을 가지고 있는지를 밝혀내기 위해 진행되었다.

Dental Pulp Stem Cells are superior to other types of adult stem cell. Because of teeth are easy to access and are extracted throughout life. A supernumerary tooth is an important clinical problem found in various populations of the world. The incidence of supernumerary teeth varies depending on the literature source. Pediatric dentists are routinely extracted them. However, no studies have been reported regarding Dental Pulp stem cells in a supernumerary tooth, and we failed to note that a valuable source of human stem cell. Herein, we tried to show that a supernumerary tooth contains cells that display the characteristic features of stem cells.
