...Paul Martin; Akbar Khan; Julian Lewis ABSTRACT Peripheral nerves travel to their targets along precise routes, and it is likely that different cues provide guidance at different stages of the journey. In a develop­ing chick limb, the cutaneous nerve fibres follow at first deep mixed nerve trunks...

...C. P. Cottrill; Paul T. Sharpe; Lewis Wolpert ABSTRACT A technique which identifies cells differing in surface character, aqueous two-phase partition using thin-layer countercurrent distribution (TLCCD), has been used to study differentiation and pattern formation in the developing chick limb bud...

... are discussed in the light of two current models describing the developing chick limb and analysed diagrammatically within the framework of one of these models, the polar coordinate model. In an additional five cases, rotated right quail wing bud tips were grafted onto right chick wing bud stumps. Resulting...

...K. M. Bell; J. C. McLachlan ABSTRACT Two regions of the chick limb bud — the apical ectodermal ridge and the zone of polarizing activity — have been shown to influence cell division and pattern formation during normal development and following surgical manipulation. In this study, using a simple...
