Only 1-3 cell wide coherent migrating neural crest cells connected from dorsal aspect of somite to dorsal aspect of notochord were counted as a stream
Counts were carried out in two somites of each of four or five embryos
Counts were carried out in two somites lacking slow muscle of each of five embryos
Counts were carried out in two somites of each of three embryos and one somite of one embryo in which transplanted adaxial cells were present in the indicated position
Counts were carried out in all somites of five embryos in which transplanted cells were present in the indicated position
Counts were carried out in all somites of eight embryos in which transplanted cells were present in the indicated position
