用一种新的定量分析结果的方法，对早期鸡肢芽顶端外胚层脊的去除效果进行了重新研究。零件放置的近端-远端序列的概念得到了证实，并有证据表明，这是一个连续的过程，在更远的水平上，从一个细胞指定的水平逐渐变化到另一个细胞。然后，根据“进展区”模型对结果进行解释，以表明它们与模型一致，并为其参数之一，即尖端位置值随时间的变化率提供了分析。
The effect of removal of the apical ectodermal ridge from the early chick limb-bud is re-examined using a new quantitative method of analysis of results. The concept of the proximo-distal sequence of laying down of parts is confirmed and evidence is presented thatthis proceeds as a continuous process, there being a gradual change in the level specified from one cell to another at a more distal level. The results are then interpreted in terms of the ‘progress zone’ model to show that they are both consistent with the model and that they provide an assay for one of its parameters, the rate of change of positional value with time at the tip.
