초록
이 연구의 목적은 정량적 실시간 중합효소 연쇄 반응법을 이용하여 발거된 과잉치 치수 및 치주인대 줄기세포의 유전자 발현을 비교하는 것이다. 전신병력이 없는 만 6세 남아 2명의 상악 전치부에 매복된 과잉치를 발거하였다. 같은 날 치수 및 치주인대 세포를 채취하였고, 3 계대까지 계대배양하였다. 분석을 위해 상아질모세포 특이 유전자인 Alkaline phosphatase (ALP), Dentin Matrix Protein 1 (DMP-1), Dentin sialophosphoprotein (DSPP), Osteocalcin (OCN) 그리고 Osteonectin (ONT)을 사용했고, glyceraldehyde 3-phosphate dehydrogenase (GAPDH)을 대조군으로 설정했다. 과잉치 치수 세포에서는 ONT, OCN, ALP, DMP-1, DSPP 순서로 발현량이 많았고, 치주인대 세포에서는 DMP-1과 DSPP의 순서만 바뀌었다. 치주인대 세포보다 치수 세포에서 모든 유전자의 발현량이 많았다. 이러한 상아질모세포의 특성을 고려해 보았을 때, 다른 조직으로의 분화 가능성이 있는 과잉치 줄기세포는 유용한 공여부로서 그잠재력이 있음을 알 수 있었다.
Abstract
The purpose of this study is to compare the properties of dental pulp and periodontal ligament stem cells from extracted supernumerary teeth by quantitative real-time PCR. Impacted supernumerary teeth in the maxillary anterior region were extracted. Dental pulp and periodontal ligament cells were collected from extracted supernumerary teeth on the same day. After isolation and culture of cells, compare characterization of them by using qRT-PCR. Primer sequences for odontoblasts are ONT, ALP, OCN, DMP-1 and DSPP. On dental pulp group, ONT has the largest quantity of gene expression, followed by OCN, ALP, DMP-1 and DSPP. On periodontal ligament group, ONT has the largest quantity of gene expression, followed by OCN, ALP, DSPP and DMP- 1. Analysis of quantitative gene expression data using relative quantification showed that the expression of all genes decreased in periodontal ligament cells. Dental pulp and periodontal ligament stem cells from supernumerary teeth have the properties of odontoblasts. Considering that properties, supernumerary teeth were considered a useful donor site of dental pulp and periodontal ligament stem cells.
