It is well known that the apical ectodermal ridge (AER) and the zone of polarizing activity (ZPA) play a major role in growth and patterning of the limb. But a mechanism underlying species-specific growth of the limb has not yet been fully elucidated. To investigate the role of AER and ZPA in limb s

Microchemical procedures were employed for the quantitative assay of acetylcholinesterase ( AChE) and choline acetyltransferase (ChAc) activity in the brachial spinal cord of chick embryos from 3.5 to 21 days' incubation. The activity of AChE increased nearly 10-fold during the 60-hour period from s
FGF10 and FGF8, which are reciprocally expressed by the mesoderm and AER of the developing limb bud, have been implicated in limb initiation, outgrowth, and patterning. FGF10 and FGF8 signal through the FGFR2b and FGFR2c alternative splice isoforms, respectively [
