使用小鼠ES细胞分化的胚胎干细胞试验(EST)是体外胚胎毒性筛选试验方案。这种EST方案需要10天或更长的培养,因为收缩心肌细胞的分化。因此,我们开发了一种新的评估方法,使用碱性磷酸酶(ALP)活性作为终点,并比较了EST和我们的方法获得的结果,对四种牙科单体。通过EST法发现Bis-GMA具有弱的胚胎毒性,但通过我们使用ALP活性的方法发现无胚胎毒性。通过这些方法,在其他单体的结果中没有发现差异。将来,应该收集更多的数据来建立我们的方法。
The Embryo Stem Cell Test (EST) using mouse ES cell differentiation is an in vitro embryotoxicity screening test protocol. This EST protocol requires a 10-day or longer culture because the differentiation of contracting myocardial cells. Therefore, we developed a novel assessment method using alkaline phosphatase (ALP) activity as an endpoint, and compared the results obtained with the EST and our methods regarding four kinds of dental monomer. Bis-GMA was found to be weakly embryotoxic by the EST method, but non-embryotoxic by our method using ALP activity. No difference was found in the results for the other monomers by these methods. In the future, more data should be collected to establish our method.
