Abstract

Culture of osteoblast is extremely valuable in analyzing biological features that are specific to bone. ENA-A, ENA actimineral resource A, is a seaweed origin alkaline water. To investigate the bioactivity of ENA which act on bone metabolism, we studied the effects of a ENA on the activity of osteoblast MC3T3-E1 cells. ENA (1, 2, 4%) dose-dependently increased survival (p<0.05) and alkaline phosphatase activity (p<0.05) on MC3T3-E1 cell. And examined histochemistry and nodule formation according to the time course. To determine the expression patterns of bone-related proteins during the MC3T3-E1 osteoblast-like cell differentiation by using RT-PCR. This study suggest that ENA may promote the function of osteoblastic cells and play an important role in bone formation.

골조직은 골아세포, 파골세포, 골세포 등으로 구성되며, 골개조시 여러 인자가 세포증식, 분화, 활성화 및 골대사 조절에 관여한다. 이때 조골세포의 활성은 골형성에 중요하므로, 본 연구에서는 MC3T3-E1 조골세포주를 이용하여 해조류로 조제한 알칼리의 ENA-A 이온수가 조골세포의 증식과 분화활성에 미치는 영향을 조사하였다. 먼저 ENA-A 이온수가 조골세포의 성장에 미치는 영향을 MTT 검색법으로 조사 한 결과, ENA-A 이온수 2% 처리시 대조군과 비교하여 134% 증가하여 조골세포에 대해 높은 성장률을 보였다. 또한 ALP 효소 활성에 미치는 영향을 9일간 배양하여 그 변화를 측정하였다. 결과, 농도 1, 2, 4, 8% 처리시 112, 150, 188%까지 ALP 활성을 증가시켰다. ENA-A 이온수는 다시 ALP 효소 염색법과 Alizarin Red 염색으로 조골세포의 ALP활성유도, 분화와 석회화 형성능을 재확인하였으며 골기질 유전자의 발현의 변화도 확인하였다. 이에 본 연구결과를 통해 각종 무기질 성분을 함유한 ENA 이온수가 조골세포의 분화시에 hydroxyapatite 형성에 영향을 줌으로써 골다공증 예방에 효과가 있을것으로 생각하여 이를 보고하는 바이다.
