夹竹桃天蛾胚胎细胞的原代培养

Research Advances on Primary Culture of Daphnis nerii Embronic Cell in Vitro

夹竹桃天蛾是一种世界性害虫。以夹竹桃天蛾虫卵为材料,通过机械破碎的方法对其进行原代培养,确定了Grace’s insect medium为最适合的培养基。对夹竹桃天蛾胚胎细胞进行了长达12月的原代培养,观察到在原代培养物中分化出的多种形态的原代细胞。夹竹桃天蛾胚胎细胞的原代培养初探为进一步建立夹竹桃天蛾细胞系提供了重要的实验依据。

Daphnis nerii(Linnaeus)is a notorious pest that has a wide geographic distribution.In this study,we employed a mechanical crushing method to establish primary cultures of Daphnis nerii eggs and determined Grace’s insect medium as the most optimal culture medium.Primary culture of Daphnis nerii embryonic cells lasted up to 12 months,and various forms of primary cells were differ-entiated in the primary culture.Our result provides crucial experimental basis for establishing Daph-nis nerii cell lines in future research.
