在人工海水中，在pH 7.0和7.8的各种浓度的ZnCl2中孵育海胆Lytechinus pictus的胚胎不同的时间段。一般而言，锌处理限制内胚层和间充质衍生物的发育，并且锌可被归类为动物化物质。考虑到在发育过程中，65锌被胚胎吸收的时间和锌对蛋白质合成，细胞分裂和细胞迁移的可能影响，锌效应的特异性进行了分析。探讨了锌作为一种毒性物质非特异性发挥作用的可能性。锌的动物化特性可能是在植物性半体的结构分化时发育过程中非特异性停滞的结果。
Embryos of the sea urchin Lytechinus pictus were incubated for different periods of time in various concentrations of ZnCl2 in artificial sea water at pH 7.0 and 7.8. In general, zinc treatment restricts the development of endoderm and mesenchyme derivatives and zinc may be classified as an animalizing substance. The specificity of the zinc effects is analyzed considering the time during development that 65Zn is taken up by the embryo and the possible effects of zinc on protein synthesis, cell division and cell migration. The possibility that zinc exerts its effect non-specifically as a toxic substance is explored. The animalizing properties of zinc may be the result of a non-specific arrest in development at the time when the structures derived from the vegetal half are differentiating.
