The dependence of the differentiation-pattern of competent amphibian ectoderm on the proportion of inducing and induced material was studied. To do so different masses of LiCl-treated tissue were combined with a constant mass of untreated material. LiCl-treated isolates corresponding in size with the treated portions in the combinations served as controls. The experiments seem to show at least three factors responsible for the differentiation-pattern of the combinations: the number of inducing cells, the number of cells to be induced, and the competence of the ectoderm, which depends on the stage of development.
研究了有能力的两栖类外胚层分化模式对诱导物质与被诱导物质比例的依赖性。为此，将不同质量的经LiCl处理的组织与恒定质量的未处理物质相结合。与组合中经处理部分大小相当的经LiCl处理的分离物用作对照。实验似乎表明，至少有三个因素决定了组合的分化模式：诱导细胞的数量、待诱导细胞的数量以及外胚层的能力，而外胚层的能力取决于发育阶段。
