Abstract
An estimate of the time required for positional signalling in the chick wing bud was obtained by grafting irradiated quail polarizing regions to host wing buds and removing them at various times. Such polarizing regions must be present for at least 15 h to induce additional structures in the host wings. This results is discussed in terms of a diffusible morphogen model.
摘要
通过将经辐照的鹌鹑极化区域移植到宿主翅芽上，并在不同时间移除它们，获得了鸡胚翅芽中位置信号传导所需时间的估计值。这种极化区域必须存在至少15小时才能在宿主翅膀中诱导出额外的结构。根据可扩散形态发生素模型对这一结果进行了讨论。
